SecLists.Org Security Mailing List Archive
Any hacker will tell you that the latest news and exploits are not found on any web site—not even Insecure.Org. No, the cutting edge in security research is and will continue to be the full disclosure mailing lists such as Bugtraq. Here we provide web archives and RSS feeds (now including message extracts), updated in real-time, for many of our favorite lists.

NSConnection Probe Harrison Neal (Oct 11)
Good day,
It appears that nmap doesn't currently recognize TCP-bound NSConnection (
https://developer.apple.com/documentation/foundation/nsconnection ).
Example server code:
NSConnection *a = [NSConnection connectionWithReceivePort:[[NSSocketPort
alloc] init] sendPort:nil];
[a setRootObject:[[NSObject alloc] init]];
[a runInNewThread];
[NSThread sleepForTimeInterval:300.0f];

NSE scripts for SNMPv3? Johan Kuuse (Oct 03)
Hi, my first mail to this list,
I have used (and modified) quite a few NSE scripts for SNMP.
Anyhow, AFAIK, all SNMP scripts (except "snmp-info") are limited to SNMPv1
and SNMPv2c:
nmap --script-help=snmp* | grep -B3 -A1 -i v3

NPCAP 1.60 high CPU usage with pcap filter that does not pass anything (Win10) Vladimir Soldatov (Sep 17)
Hi guys,
I've a setup (Win10, Intel X520, NPCAP 1.60) with relatively high traffic
around 700 Mbit/s and I am trying to test the following cases:
1. Capture everything with empty pcap filter and just print stats with some
period calculating captured data size
2. Capture nothing with an intentionally created filter that does not match
the received traffic at all.
3. Capture some subset of traffic like 10%.
In all the cases, CPU usage...

How to make a minimal HTTPS request with ncat --ssl with explicit HTTP content? Ciro Santilli OurBigBook via dev (Sep 17)
Hello, I was trying for fun to make an HTTPS request with explicit hand-written HTTP content.
Something analogous to:
printf 'GET / HTTP/1.1\r\nHost: example.com\r\n\r\n' | ncat example.com 80
but for HTTPS. After Googling one of the tools that I found that seemed it might do the job was ncat from the nmap

Automatic protocol selection? Roy Sigurd Karlsbakk (Jul 06)
Hi all
Sometimes I use nmap in my scripts and since I'm in a mixed environment, where most of the hosts are dual protocol, not
all are, and some are only on IPv4 or IPv6, depending on the type of equipment and their function. Most other software,
will just default to a single protocol, typically IPv6, and then fall back to the other if the first fails. At first I
thought using the -6 flag would do so (as it says 'Enable IPv6...
Fix ndiff.bat issue on Windows georges.zwing (Jul 04)
Hi,
I created this PR <https://github.com/nmap/nmap/pull/2865> to fix this

Windows. It also removes the requirement to have Python installed separately
from Zenmap.

look somewhere else?

Dear Nmap community,
Today is Nmap’s 26th birthday, which reminded me that I hadn’t yet

improvement was the Zenmap and Ndiff upgrades from the obsolete Python 2
language to Python 3 on all platforms. Big thanks to Daniel Miller, Jakub

Other Excellent Security Lists
Bugtraq — The premier general security mailing list. Vulnerabilities are often announced here first, so check frequently!
Security Basics — A high-volume list which permits people to ask "stupid questions" without being derided as "n00bs". I recommend this list to network security newbies, but be sure to read Bugtraq and other lists as well.
Penetration Testing — While this list is intended for "professionals", participants frequenly disclose techniques and strategies that would be useful to anyone with a practical interest in security and network auditing.
Info Security News — Carries news items (generally from mainstream sources) that relate to security.
IDS Focus — Technical discussion about Intrusion Detection Systems. You can also read the archives of a previous IDS list
Web App Security — Provides insights on the unique challenges which make web applications notoriously hard to secure, as well as attack methods including SQL injection, cross-site scripting (XSS), cross-site request forgery, and more.
Daily Dave — This technical discussion list covers vulnerability research, exploit development, and security events/gossip. It was started by ImmunitySec founder Dave Aitel and many security luminaries participate. Many posts simply advertise Immunity products, but you can't really fault Dave for being self-promotional on a list named DailyDave.

It's likely this is going to happen anyway, the new Mistral just dropped
and seems to perform roughly on par with llama3 and gpt4o, so the next wave
of fine tuned versions like dolphin are almost certainly coming soon.
OpenAI also has announced free fine tuning of gpt4o mini until late
September (up to 2m tokens/day) so it may be possible to fine tune around
some of its guardrails for a reasonable cost.

while OpenSSL rates this issue as "low severity", SuSE assesses it as

Re: CVE-2024-47191: Local root exploit in the PAM module pam_oath.so Solar Designer (Oct 17)
Looks good to me.
There's a subtle issue here - another user's (or root's) temporary file
may be hard-linked and st_nlink may be back to 1 after the file is
unlinked by its original creator/user. For example, tmpfile(3) unlinks
the file right away, yet the calling program is expected to proceed to
use it. In that case, an attacker winning the race could manipulate
content of another user's temporary file, which that...

Hi,
Exactly. The privilege-drop is only an extra hardening. The patch
first attempts to securely determine the ownership of the
oath-usersfile, then drops privileges to the owner of the file for
further processing.
The privilege-drop in our path is defense-in-depth. The file operations
used should be robust on their own already. Dealing with file system
APIs securely is such contexts is quite a complex task as can be seen in

Re: CVE-2024-47191: Local root exploit in the PAM module pam_oath.so Solar Designer (Oct 15)
As I understand, the SUSE patch already does that.
The detail here may be different. And importantly, the final path
component must be owned strictly by the target user (not by root, unless
the target user is root).
Both the SUSE and the upstream patch try to do two things at once: drop
privileges and access files safer. Maybe I missed, but I think neither
of you specified whether these two things are intended as required
complementary parts...
Re: CVE-2024-47191: Local root exploit in the PAM module pam_oath.so Demi Marie Obenour (Oct 15)
What about opening the path one portion at a time using openat() with
O_NOFOLLOW (and, as applicable, O_DIRECTORY), ensuring that each portion
is not "." or "..", does not contain "/", and is owned by either the
target user or root? This solves all race conditions and does not
require spawning another process.

RE: IEEE MACsec Bertilsson , Björn via NANOG (Oct 23)
The biggest pitfall for telecom with MACSEC, is that PTP/SyncE and MACSEC on the same physical interface simultaneously
is mostly not supported. Many claims that you can do both, but they don’t mention that it can’t be done at the same
time. There are some newer models of Juniper ACX coming with that, one model of Cisco NCS (but not officially

Re: IEEE MACsec Dave Cohen (Oct 22)
I would caution anyone running MACsec on a link leveraging a provider
circuit between them to quadruple check that the provider link supports
customer use of MACsec. In theory MACsec will operate just fine over a
Layer 2 link but carriers tend to not like unanticipated bits get appended
or inserted into frame headers. In my carrier days, $dayjob's L2 products
tended to be highly interoperable relative to the industry norm, and we

Re: IEEE MACsec Stephen Stuart (Oct 22)
If you are going to deploy MACSEC, my advice is test, test, and test,
especially (but not only) if you have different vendors'
implementations of MACSEC on either end of the link.
Test that MACSEC comes up.
Test that it recovers from link flaps.
Test key rotation.
Test recovery from link flaps during key rotation.
Test all permutations of recovery from admin down/up on both sides.
Test everything you can think of, then think of more...
Re: IEEE MACsec Tarko Tikan (Oct 22)
hey,
What we are seeing now is MACsec getting integrated into latest NPUs
directly. So far it has been mostly implemented by separate chips or in
PHYs (or combination). This has, in some cases, limited you to what
ports you can use MACsec on. It also had challenges with sync/PTP,
per-vlan MACsec etc.
So while it is proven technology and works well we are still seeing
innovation/improvements.
Re: IEEE MACsec Brandon Martin (Oct 22)
MACsec is also really useful where you need point-to-point protection of
traffic that isn't easily manipulated at L3 or may not even run over IP
but that may transit publicly accessible infrastructure. Utility SCADA
traffic is an example, and MACsec can be very useful on those networks
as they often transition from wireless to fiber.
Re: IEEE MACsec Crist Clark (Oct 21)
It is definitely deployed out there. I wouldn't worry too much about
reading the specs. All of the implementations I've dealt with are only
partial implementations. They almost all are limited to "point to point"
functionality.
As for comparing to IPsec, IPsec came out of a different time. It is more
of framework with a zillion knobs, and lots of room for customization and
future changes. The keying isn't even a part of...
Re: IEEE MACsec Tom Beecher (Oct 21)
There's certainly a penalty paid for the extra time encrypting and
decrypting , which of course can aggregate over a large number of protected
links.
But unless you're trying to manage latency budgets in the microseconds
range it's not likely to be an issue.
Re: IEEE MACsec John Schiel (Oct 21)
Thanks.
I threw this out there not knowing how fast someone would respond.
I only heard about this recently and am surprised it as as old as it is.
Regarding speed, the first few pages I hit made a comment that it was
slower because of packet overhead. I'm reading more and that is less of
a concern.

Re: IEEE MACsec Saku Ytti (Oct 21)
I guess it depends on wireless technology, but 802.11xyzzy comes with
an encryption solution already so isn't really a target of interest.
Not really, implementation detail.
Definitely not supported on all devices, you tend to pay extra, but
getting an increasingly small premium to pay. May become essentially
free, depending on demand.
Speed doesn't have anything to do with layer2 or layer3, you may be
assuming that ipsec is software...
IEEE MACsec John Schiel (Oct 21)
I know this is a NANOG forum but curious how widespread usage of MACsec
might be. (https://1.ieee802.org/security/802-1ae/).Currently reading
the spec but wanted to pose some questions.
I'm seeing some pitfalls:
1) May not work over wireless LAN devices?
2) Needs a centralized key server.
3) May not be supportable on all devices?
Purported to be faster on the LAN than IPsec because MACsec is on layer 2.
Thoughts?

Questions about IPS-Policy Bestell_E-Mail via Snort-sigs (Oct 22)
Hello.
First of all, please excuse me if this question is asked a lot.
I am a beginner and currently using the IPS Policy with the Business License.
I am not sure if Personal or Business License is right for me. Are the IPS policies different in any way for these two
licenses?
Best regards

Re: Hi all! (and a snort sig question) Al Lewis (allewi) via Snort-sigs (Oct 10)
Wouldnt it be easier to just use the IP variable?
i.e replace the EXTERNAL_NET and use a variable or IP?

Re: Hi all! (and a snort sig question) Rob Vandenbrink via Snort-sigs (Oct 10)
Ah, makes sense
I’ll count bytes, but I don’t think the ordering of extensions is dictated…
Playing with this tomorrow hopefully
Hi Rob
At this point of inspection, the payload is handled by the SSL inspector, and not by the HTTP inspector. So, we cannot
use the HTTP buffers.
So, is it possible for you to match on the relevant bytes using content matches without using buffers?
This is my understanding. I could be wrong :/

Snort capturing traffic from the entire network instead of just the IP Assigned NTWIGA MURITHI via Snort-sigs (Oct 10)
Goodmorning,
I downloaded the registered rules. And configured snort.lua IP using the
following
HOME_NET = '10.2.60.134'
EXTERNAL_NET = '!$HOME_NET'
The problem is snort is capturing all the traffic from other IPs when i run
this command
sudo snort -c /usr/local/etc/snort/snort.lua -i eth0 -A alert_fast
--plugin-path "/usr/local/etc/so_rules/"

Re: Hi all! (and a snort sig question) Rob Vandenbrink via Snort-sigs (Oct 10)
Cool, will do
If I browse to an IP address, there is never an SNI (since there’s no “server name” to put there). Confirmed this with
a PCAP.
So my thought was to write a sig that looks for an null SNI value, my current best gues would be this one, which should
look for an FQDN in the SNI field, and if there’s no dot (which there should be) then trigger the alert.

Re: Hi all! (and a snort sig question) Rob Vandenbrink via Snort-sigs (Oct 10)
Ah, I thought that since the Hello packets are unencrypted that snort would still inspect at least those
I do not have decrypt turned on (given historic Cisco Firepower+Snort issues), but I think I can convince one of my
clients to give it a try now that they have new hardware and new code.
Do either of those two latest signatures that I’m trying look OK though?

Re: Hi all! (and a snort sig question) Snort User via Snort-sigs (Oct 09)
I don't think so. I would definitely use *ssl_state:client_hello; *and then
look to match the SNI portion of the SSL client hello packet and then try
matching the dotted quad pattern.
But as you are doing, the best way is to try out your sig against a pcap
