http-trane-info.nse: fix device attribution, 200-for-everything handling, nil crashes Pedro Joaquín (Oct 26)
Hi,

I'm the author of http-trane-info (Nmap 7.70).

PR #3581 fixes three bugs in it: installed equipment was reported with the
previous device's name/family/role from the second device onward, the
script crashed on firmware that omits a field in /evox/about, and the guard
against servers that answer 200 to every path let the "unknown"
identify_404 case through.

Thanks,

New OpenSSH composite key type in version 10. Loganaden Velvindron (Oct 20)
Hi nmap developers,

There has been a new key type released with OpenSSH v10 which is called:

"hybrid post-quantum ssh-mldsa44-ed25519 signature
algorithm."

I've opened a PR and would welcome feedback from nmap developers:
https://github.com/nmap/nmap/pull/3562

Kind regards,

Request for review: Windows MaxUserPort / WSL2 networking fix (PR #3499) 山﨑結友 (Oct 03)
Hi all,

I'd appreciate a review of this PR:
https://github.com/nmap/nmap/pull/3499

Nmap's "Network Performance Improvements" installer option sets
MaxUserPort=65534. On Windows 11, I found that this changes the dynamic
port range from 49152–65535 to 1024–65534. This has been linked to WSL2
mirrored networking failures, with several users tracing the problem
to the Nmap installer:...

Re:New OS fingerprint: China Unicom ONT/ONU (Realtek/Boa) gbfdhenr (Liang Xiangan) (Aug 01)
Hi Nmap developers,

I'd like to submit service fingerprints for a China Unicom GPON ONT (model PT927G) that I found in my home network.
This device runs a Linux-based firmware (kernel 3.18.24) and exposes several services.

**Device Information**:
- Model: PT927G
- Vendor: China Unicom (customized)
- Hardware hint: SMB share comment mentions "Realtek", suggesting a Realtek chipset.

**Service Fingerprints**:
1. **HTTP (port...

Re:Correction: Huawei router misidentified as Netgear switch (fingerprint included) gbfdhenr (Liang Xiangan) (Aug 01)
Hi developers,

I'd like to add a service fingerprint for port 37443/tcp on the Huawei AX3 router.

This port runs SSL/TLS and requires client certificate authentication (mTLS). When connecting with a self-signed client
certificate, the server rejects it with a "unknown ca" alert, indicating that it verifies the client certificate
against a trusted CA.

**Certificate details:**

Subject: CN=Master.ws7100-10, O=Huawei Technologies...

Re:Correction: Huawei router misidentified as Netgear switch (fingerprint included) gbfdhenr (Liang Xiangan) (Aug 01)
Hi Nmap developers,

Following up on my previous submissions (OS fingerprint and NSE script for the Huawei AX3), I've conducted a full port
scan and discovered two additional services that may help refine the service fingerprint database.

**1. Port 37215/tcp – UPnP**
- Service identified as: `Huawei ATP gateway upnpd`
- This seems to be already correctly matched in `nmap-service-probes`. I just wanted to confirm its presence.

**2. Port...

PATCH] New NSE script: huawei-ax3-info.nse

Hi Nmap developers,

Following up on my previous OS fingerprint submission for the Huawei AX3 router (Message-ID:
<335797c9.5fe8.19fb73084b0.Coremail.gbfdhenr () 163 com>), I've developed an NSE script to extract device information
from the router's /api/system/deviceinfo endpoint.

Correction: Huawei router misidentified as Netgear switch (fingerprint included) gbfdhenr (Liang Xiangan) (Jul 31)
Hi Nmap team,

I've encountered a clear OS detection misidentification that I believe should be corrected.

**Device in question**:
- A Huawei home router (MAC OUI: 30:A9:98 -> Huawei Device)
- Open ports: 53, 80, 443 (typical router/AP, not a headless switch)
- Running: Linux-based firmware (likely 3.18.24)

**Current incorrect result**:
Nmap 7.99 reports it as: "Netgear GS108Tv3, GS110Tv3, or GS308T switch (Linux 3.18.24)"...

Npcap Version 1.82 Released with VLAN Tagging and More Gordon Fyodor Lyon (Apr 28)
Dear Nmap Community,

In preparation for an imminent Nmap release (hopefully this week!), we have
released Version 1.82 of our Npcap Windows packet capture and transmission
driver. It builds upon the recent 1.81 release to add support for VLAN
tagging. This allows you to select for packets directed to a certain VLAN
or just inspect the VLAN headers on any packets received. It's especially
useful for Wireshark users. You can also now send...

Nmap 7.95 released: OS and service detection signatures galore! Gordon Fyodor Lyon (May 05)
Dear Nmap Community,

I just arrived in San Francisco for the RSA conference and am delighted to
announce our Nmap Version 7.95 release! I'm most excited that we finally
tackled our backlog of OS and service detection fingerprint submissions.
We're not talking about dozens or hundreds of them-we processed more than
6,500 fingerprints!

For OS detection, we added 336 signatures, bringing the new total to 6,036.
Additions include iOS 15...

Apache Struts2 Tiles Plugin <=7.4.0 and >=6.3.0 Preparer Cache Vulnerabilities Daniel Owens via Fulldisclosure (Nov 04)
The Apache Struts2 Tiles plugin version <=7.4.0 (and >=6.3.0) codebase includes a `ViewPreparer` construct, replete
with multiple ViewPreparer factories, that contains several important vulnerabilities including unsynchronised,
unbounded caches. The lack of proper synchronisation means that certain factories will create caches that race,
risking lost cache entries, corrupted internal bucket states under load (this can result in infinite...

unixODBC <=2.3.14 Rude Truncation via Narrowing Conversion Causes Out-of-Bounds `memcpy` Daniel Owens via Fulldisclosure (Nov 04)
unixODBC versions <=2.3.14 contain a rude truncation of a 64-bit `SQLLEN` `buffer_length` to a 32-bit `int` without
verifying that it produces a valid, positive value. The result is later passed to `memcpy`, causing the information
system to crash or, if carefully chosen, enabling attackers to write adjacent memory under certain circumstances (e.g.,
a buffer length that wraps to a small positive integer or triggers an undersized allocation...

unixODBC <=2.3.14 Multiple Races Daniel Owens via Fulldisclosure (Nov 04)
The unixODBC driver manager library contains multiple races of importance / interest, including a set of data races in
the connection-pooling configuration state data that can cause one thread to read a half-written pool-size or timeout
value, which can lead to a variety of harmful effects, as well as a race between teardown and error-handling
functionality that can result in double-frees and use-after-frees. Other races exist within the...

unixODBC <=2.3.14 Multiple Heap Buffer Overflows, Underflows, and Over-Reads Daniel Owens via Fulldisclosure (Nov 04)
unixODBC versions 2.3.14 and below contain multiple heap buffer overflows, underflows, and over-reads. Attackers who
can influence various arguments passed thereto can trigger the heap-based buffer overflows inside of the unixODBC
driver manager itself, potentially corrupting the shared heap state across connections, crash the driver manager
(thereby causing denial of service conditions, multi-tenant data loss, and such related issues,...

Apache Struts2 Core Arbitrary Code Execution via OGNL Sandbox Escape Daniel Owens via Fulldisclosure (Nov 01)
Description
Apache Struts2 Core version 7.4.0 and below attempt to prevent arbitrary code execution via Object-Graph Navigation
Language (OGNL) through several different mechanisms but only in a cursory fashion -- the libraries only guard against
immediate calls evaluated by the OGNL engine via `SecurityMemberAccess`, but an allowed call that, instead, accepts
nested arguments and, itself, invokes reflection internally executes outside of the...

Apache Struts2 Core TokenHelper Token Cryptographic Timing Side-Channel Daniel Owens via Fulldisclosure (Nov 01)
Description
The Apache Struts2 Core 7.4.0 and below performs session token comparisons cryptographically insecure early-exit
comparison functions (e.g., `!=`, `memcmp`, byte-by-byte loops with `break`) that return as soon as the first
mismatched byte is encountered. The execution time of the comparison is therefore proportional to the number of
leading bytes that match, creating a measurable timing side-channel. Importantly, this...

Apache Struts2 Spring Plugin Uses a Previously Closed Resource Daniel Owens via Fulldisclosure (Nov 01)
Description
The Apache Struts2 Spring Plugin opens a Spring `ApplicationContex` via a try-with-resources block and, outside of said
block, then continues to use the closed resource, resulting in an uncaught `IllegalStateException`. This particular
issue prevents proper functionality and indicates poor code quality and code review standards and processes, while not
being, itself, otherwise excessively meaningful for a production environment...

Apache Struts2 Core Integer Overflow Daniel Owens via Fulldisclosure (Nov 01)
Description
Apache Struts2 Core version 7.4.0 and below fails to properly prevent integer overflows, causing wrap-arounds and other
issues on a downstream forced casting into types smaller than `BigInteger`. Importantly, this finding underscores why
all applications using Struts and other such platforms should perform their own input validation checks and not blindly
assume that the upstream Struts2 code has done as such, but the finding also...

Apache Struts2 Core Cross-Origin Protection Exemption Miskeyed to a Deployment-Wide Path Daniel Owens via Fulldisclosure (Nov 01)
Description
Apache Struts2 Core version 7.4.0 and below's `FetchMetadataInterceptor`, `CoepInterceptor`, and `CoopInterceptor` each
compare their `exemptedPaths` configuration -- a per-interceptor-reference, administrator-supplied set of paths
intended to exempt specific actions from the corresponding cross-origin protection -- against
`HttpServletRequest.getContextPath()`. `getContextPath()` is fixed for the entire deployed web...

Apache Struts2 REST Plugin Fails to Properly Parse Chunked Requests Daniel Owens via Fulldisclosure (Nov 01)
Description
The Apache Struts2 REST Plugin's (version 7.4.0 and below) `ContentTypeInterceptor.intercept(ActionInvocation)` only
deserialises a request body and enforces the `struts.rest.content.maxLength` bound when
`HttpServletRequest#getContentLength()` returns a positive value. `getContentLength()` returns `-1` whenever the
`Content-Length` header is absent, which normal and appropriate for any Hypertext Transfer Protocol (HTTP)...

Apache Struts2 REST Plugin Untrimmed `Accept` Header Tokens Break Content Negation Fallback Daniel Owens via Fulldisclosure (Nov 01)
Description
The Apache Struts2 REST Plugin's `DefaultContentTypeHandlerManager.getHandlerForResponse(HttpServletRequest,
HttpServletResponse)` splits the `Accept` header on commas and passes each resulting token directly to
`findHandler(String)` without trimming leading or trailing whitespace. `findHandler(String)` only retries a trimmed
lookup when a token contains a semicolon (`;`), so a token that merely carries a leading space has no...

Apache Struts2 JSON Plugin Insecure Deserialisation -- Object Deserialisation Element-Count Limit Bypass Daniel Owens via Fulldisclosure (Nov 01)
As of the current versions of the Apache Struts2 JSON Plugin (e.g., version 7.4.0 and the 7.5.0 snapshot dated 28
October 2026), attackers can bypass the element-count limit purported to protect Object deserialisation added to said
code as part of the WW-5618 and S2-072 "hardening controls". Please note that this vulnerability and the attack string
is different than the previously reported bypass against the JSON array...

RE//verse, DistrictCon, an Anole Friend Dave Aitel via Dailydave (Feb 02)
Last month was DistrictCon, a great conference that I did not attend
because the sky decided to dump snow on Washington, DC. Anyone who has
spent more than ten minutes in that city knows this is how you cancel every
flight out of DCA and turn the roads into skating rinks filled with deeply
furious government contractors. Life is short, so I remained in Miami where
it was 80 degrees and everyone was pretending winter is a myth.

feeling the air Dave Aitel via Dailydave (Jan 05)
For reasons I still don’t fully understand, Miami Beach has enormous
colonies of turkey vultures. You’ll see them circling over the city and the
interstates, perched like huge awkward toddlers on lampposts, or standing
motionless as a shadow in the strip of grass between the road and the blue
water of the bay. If you look up at almost any moment, there’s a column of
them somewhere overhead, wings spread wide, fingers splayed, feeling the...

Re: Defense ? Dean Pierce via Dailydave (Nov 16)
I like the idea of having a software supply chain that people can pay into
that basically funds a universal bug bounty system for anything that
matters.

You can put systems in place that utilize zero knowledge exploitability
proofs to automate bounty triage, so it doesn't even need to be run by a
central trusted entity. As the bounty markets stabilize, what you're left
with is a software ecosystem where anyone can build what they need...

Re: Defense ? Chris Anley via Dailydave (Nov 16)
(gingerly raises head above parapet)

Historically, “we’ve” moved the bar in defense.

- Everything is now in the cloud, accessible 24/7 via APIs whose keys are stored in plaintext alongside code, or via
preauthenticated sessions
- Everything has ~40 dependencies, each of which has ~40 dependencies, etc, which, combined with a published CVE rate
of 1 per 15 minutes (calendar year 2024), means that patching an enterprise before an...

Re: Defense ? Alfonso De Gregorio via Dailydave (Nov 16)
Imbalances in the skills and workforce are real. The gap remains hard
to bridge also in the presence of greater degrees of automation that
AI buys us, because, at this stage, we want humans to be in the loop –
and for good reasons – and, also, cause we are not going to grow the
skillset faster than the attack surface, I am afraid.

I hate to sound like a broken record, but I will take a bite
regardless: those imbalances are a byproduct of the...

Re: Defense ? Conan Dooley via Dailydave (Nov 16)
Reduce complexity, duplication, and scope in your infrastructure. Your
developers and infrastructure staff would need to agree on standardized
libraries, frameworks, etc, and you'd need skilled technical staff to
validate when people said doing something wasn't possible within that
scope, and make them accountable for making sure adding that level of
complexity led to business value that was greater than that overhead (vs,
say, just...

Re: Defense ? etojake--- via Dailydave (Nov 16)
The content of this message was lost. It was probably cross-posted to
multiple lists and previously handled on another list.

Defense ? Dave Aitel via Dailydave (Nov 15)
How would one actually move the actual bar in defense? A big part of me
thinks that you're just not going to patch your way out of the problem. But
the number of organizations that you can rely on to actually make a
difference seems pretty small? Like even converting every Linux binary to
rust would only make sense if you could find a team that could actually
maintain and support that code base, which I don't know that you could.

CVE-2026-113508: Apache Airflow: Logout token revocation fails open; errors silently swallowed Rahul Vats (Nov 08)
Severity: low

Affected versions:

- Apache Airflow before 3.4.0

Description:

Apache Airflow's logout endpoint attempted to revoke the presented token on the server, but any failure during
revocation was silently ignored and logout still reported success. When the auth manager redirects logout to an
external logout URL (for example the FAB or Keycloak auth managers), server-side revocation is the only thing that
invalidates the Airflow...

CVE-2026-113504: Apache Airflow: Secrets masker: pattern-based masking bounded at depth 5 returns deeply-nested registered secrets in cleartext Rahul Vats (Nov 08)
Severity: moderate

Affected versions:

- Apache Airflow before 3.4.0

Description:

Apache Airflow's secrets masker stopped descending into nested structures after five levels, so a secret registered
with the masker — for example a Connection password or a Variable value — that appeared more than five containers deep
under non-sensitive keys was shown in cleartext in task logs and rendered template fields. A user who can read task...

CVE-2026-111455: Apache Airflow: Connections API: async connection test authorizes create at enqueue but overwrites a later-created connection at commit Rahul Vats (Nov 08)
Severity: low

Affected versions:

- Apache Airflow 3.3.0 before 3.4.0

Description:

Apache Airflow's asynchronous connection test checked permissions when the test was queued — only create permission
when the connection ID did not exist yet — but, when the test completed with `commit_on_success`, wrote the tested
connection under that ID. A user allowed to create but not edit connections could overwrite a connection someone else...

CVE-2026-111454: Apache Airflow: API: asset endpoints return scheduled/producing/consuming Dag IDs the caller cannot read Rahul Vats (Nov 08)
Severity: low

Affected versions:

- Apache Airflow before 3.4.0

Description:

Apache Airflow's asset API endpoints returned the IDs of Dags that are scheduled on, produce, or consume an asset
without checking whether the caller may read those Dags. An authenticated user with asset read access could learn the
IDs of Dags they are not authorized to see. Users are advised to upgrade to apache-airflow 3.4.0 or later.

CVE-2026-111453: Apache Airflow: API: asset queuedEvents DELETE checks Dag edit on a ?dag_id query value but deletes rows for every readable Dag Rahul Vats (Nov 08)
Severity: low

Affected versions:

- Apache Airflow 3.3.2 before 3.4.0

Description:

Apache Airflow's API endpoint for deleting an asset's queued events checked Dag edit permission against the `dag_id`
query parameter, but deleted the queued events of every Dag the caller could read. An authenticated user with edit
permission on one Dag and read access to others could suppress asset-triggered runs of Dags they cannot edit. This is...

CVE-2026-111452: Apache Airflow: Secrets masker: camelCase key names (privateKey, connectionString, webhookUrl) not matched against the sensitive-field list Rahul Vats (Nov 08)
Severity: low

Affected versions:

- Apache Airflow before 3.4.0

Description:

Apache Airflow's secrets masker matched sensitive key names only in their snake_case form, so values stored under
camelCase keys such as `privateKey`, `connectionString`, `webhookUrl` or `accessKey` — for example in a Connection's
extra or a Variable — were not redacted in task logs, rendered template fields or API responses. A user who can read

CVE-2026-111421: Apache Airflow: Execution API: set_xcom skips the reserved-key check, so task-written XComs instantiate airflow.* classes on the API server Rahul Vats (Nov 08)
Severity: moderate

Affected versions:

- Apache Airflow 3.0.0 before 3.4.0

Description:

Apache Airflow's Task Execution API stored XCom values written by a task without the reserved-key check applied
elsewhere, so a Dag author's task could write an XCom that, when a user later viewed it through the API with
deserialization enabled, made the API server instantiate classes from the `airflow.*` namespace with arguments the Dag...

CVE-2026-111395: Apache Airflow: Reserved serialization keys in Dag run conf crash the scheduler or are rebuilt as objects in the Triggerer via deadline callbacks Rahul Vats (Nov 08)
Severity: moderate

Affected versions:

- Apache Airflow 3.2.0 before 3.4.0

Description:

Apache Airflow did not reject reserved serialization keys inside a Dag run's `conf`. A user allowed to trigger a Dag
that uses a deadline alert with an asynchronous callback could pass a `conf` that, once the deadline was missed, either
crashed the scheduler repeatedly or was rebuilt into objects inside the Triggerer. Users are advised to upgrade to...

CVE-2026-107474: Apache Airflow: Connections API: apprise connection "config" extra returned in cleartext Rahul Vats (Nov 08)
Severity: important

Affected versions:

- Apache Airflow before 3.4.0

Description:

The Apache Airflow connections API did not mask the apprise provider's `config` connection extra, which can embed
notification-service credentials. A user with permission to read connections could retrieve it in cleartext, although
Airflow 3 treats connection credentials as write-only.

Users are advised to upgrade to apache-airflow 3.4.0 or later....

CVE-2026-101031: Apache Airflow: Shell command injection in the example_dag_decorator example Dag via an IPv6 zone identifier Rahul Vats (Nov 08)
Severity: low

Affected versions:

- Apache Airflow 3.0.5 before 3.4.0

Description:

The `example_dag_decorator` example Dag shipped with Apache Airflow validated an IP address fetched over HTTP with
Python's `ipaddress` module and then placed it into a shell command. `ipaddress` accepts IPv6 zone identifiers

CVE-2026-96285: Apache Airflow: Scheduler: next_kwargs deserialized before the dict check, so resume data still invokes constructors Rahul Vats (Nov 08)
Severity: moderate

Affected versions:

- Apache Airflow 3.3.0 before 3.4.0

Description:

Apache Airflow 3.3.1 shipped a fix for CVE-2026-67260 that checks the scheduler's decoded `next_kwargs` value is a
dictionary, but performs that check only after deserializing the whole stored payload. Deserialization reconstructs
nested objects of classes permitted by the deserialization allow-list — which by default includes Airflow's own...

CVE-2026-86829: Apache Airflow: Deserialization of task-controlled XCom values in the Scheduler during dependency evaluation Rahul Vats (Nov 08)
Severity: important

Affected versions:

- Apache Airflow before 3.4.0

Description:

Apache Airflow's scheduler fully deserializes XCom values written by task code while evaluating task dependencies. A
Dag author, who controls what a task writes to XCom, therefore controls data that is deserialized inside the scheduler
process - a context the Airflow security model reserves for code installed by the Deployment Manager, above the...

CVE-2026-86468: Apache Airflow: CLI argv masking misses Variable values and --conn-extra, persisting secrets in audit logs Rahul Vats (Nov 08)
Severity: low

Affected versions:

- Apache Airflow before 3.4.0

Description:

Apache Airflow's CLI records its arguments in the audit log but masks secrets by argument position, so some supported
command shapes leave secrets in cleartext, for example a trailing `--description` on Variable commands, `--conn-extra`,
and the inline `--password` of `airflow keycloak-auth-manager` commands. A user who can read audit events but is denied...

CVE-2026-82337: Apache Airflow: DeadlineAlert fields bypass plugin-registration gate for scheduler-side deserialization Rahul Vats (Nov 08)
Severity: moderate

Affected versions:

- Apache Airflow before 3.4.0

Description:

Apache Airflow rebuilt deadline alert fields through generic deserialization, which imports and instantiates the class
named in the serialized Dag, in the scheduler and API server. A Dag author could cause classes within Airflow's
deserialization allow list to be constructed in those processes with arguments they control. Deployments whose Dags use...

CVE-2026-76185: Apache Airflow Task SDK: Task SDK SecretCache: non-injective team cache key enables cross-team secret disclosure in multi-team mode Rahul Vats (Nov 08)
Severity: important

Affected versions:

- Apache Airflow Task SDK 1.2.0 before 1.4.0

Description:

Apache Airflow's Task SDK secret cache built its keys from the team name and secret id with unescaped `_` delimiters,
so different (team, secret id) pairs could collide. In multi-team deployments a Dag author could read another team's
Variable or Connection value by crafting a colliding secret id. Only deployments with both...

Re: DAZN content - CDN Joel Jaeggli via NANOG (Nov 08)
The long tail of content owners that deliver via CDN would be hard to
address individually.  The CDNs that from them are however highly
amiable to delivering  over peering. You'll probably get them even via
MLPE via the exchange's route servers, but a bilateral peering with many
/ most of them is possible.
