Wierd issue: nmap/nping misses (some) icmp replies John Robson via dev (Dec 14)
Hi all,

I'm running into a weird issue that I can't quite get my head around.
As part of monitoring devices we use nmap to issue icmp echo requests
to a list of target devices, and obviously the lack of a reply is
worthy of generating an event/alert/alarm.

I am currently seeing sporadic events from a variety of target
devices, which clear on the next polling cycle (i.e. we miss one
response but get the following one sixty seconds...

Re: nmap to use with sudo (but prevent privilege escalation vectors) Robin Wood (Oct 29)
Hi
What about if you put nmap in a docker container and after each scan
threw the container away and built a new one for the next scan.

That way you could lock down as far as you can, but if the user
manages to read the shadow file or overwrite something important, they
would only destroy their instance and not affect the rest of the
system.

I will add though, my docker skills are very limited, so this is just
a vague idea that may be a load of...

Npcap Celebrates its 10th Anniversary In Space! Gordon Fyodor Lyon (Oct 05)
Dear Nmap community,

Last month we celebrated Nmap's 26th birthday and today I'm happy to share
another big milestone: Our Npcap driver for capturing and sending raw
packets on Windows turned 10 this year! From humble beginnings as a
security and modernization patch for the discontinued WinPcap project,
Npcap has become an indispensable component for both Nmap and Wireshark.
And it's used by hundreds of other software products and...

Nmap 26th Birthday Announcement: Version 7.94 Gordon Fyodor Lyon (Sep 01)
Dear Nmap community,

Today is Nmap’s 26th birthday, which reminded me that I hadn’t yet
announced our Nmap 7.94 release from May. And it’s a great one! The biggest
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
Kulík, Brian Quigley, Sam James, Eli Schwartz, Romain Leonard, Varunram
Ganesh, Pavel Zhukov, Carey Balboa, and Hasan Aliyev for...

I never thought I'd still be at it a quarter of a century later, but that's
because I also didn't anticipate such a wonderful community of users and
contributors spanning those decades. You've helped Nmap blossom from a
fairly simple port scanner to a...

Re: cpio privilege escalation vulnerability via setuid files in cpio archive Harry Sintonen via Fulldisclosure (Jan 14)
Tar does set setuid bit, but tar is not vulnerable. This is not an attack.

The user is responsible for extracting the archives to secure location
and not letting other users access to insecure setuid binaries. See:

https://www.gnu.org/software/tar/manual/html_section/Security.html#Security-rules-of-thumb

These same security considerations also apply to cpio.

Re: cpio privilege escalation vulnerability via setuid files in cpio archive Harry Sintonen via Fulldisclosure (Jan 14)
So does for example tar. The same rules that apply to tar also apply to
cpio:

"Extract from an untrusted archive only into an otherwise-empty directory.
This directory and its parent should be accessible only to trusted users."

This is a user error, not a vulnerability in cpio.

Secure By Default Part 2 Dave Aitel via Dailydave (Jan 19)
So I wrote a little draft essay on Secure By Default and opened it for
comment. I think one thing that we maybe forget in our community is that
some of the more fundamental basises of what we do never make it up to
policy-world. Langsec being the primary example. But also there's a huge
body of work in TAOSSA, Shellcoders, every offensive conference talk, etc.
that never gets put into context anywhere but in our clique.

Hey everybody,

Please note the last sentence on page 3:

Not being a fanboy of CISA, I see that quite a lot of (positive) things
have happened in the last 2 years there.

And publishing a report for that timeframe in January 2024 puts the OIG
in a questionable light regarding agility and speed.

0xC15A: Secure By Design and Secure by Default Dave Aitel via Dailydave (Jan 12)
So I have a ton of thoughts on the CISA Secure by Design and Secure by
Default push that is ongoing, as I am sure many of you do. And the first
thought is: This is not a bad way to go about business as a government
agency in general. I think it's easy to ignore how fast the USG has changed
its business practices, showing an agility that few large organizations can
match. In particular using Secure By Design as a case example.

I think one thing this community does really well, better than almost any
other community I've found, is training. It's amazing, in a way,
because this is a community of professional secret holders. And yet
everywhere you look, a hacker is putting their heart and soul into
iterating on lab exercises for their class in whatever sub-field they are
an expert in.

And giving training is hard. It's hard in the way consulting is hard,...

Re: Re: darkhttpd: timing attack and local leak of HTTP basic auth credentials Anton Luka Šijanec (Jan 24)
Hello,

I can see UID numbers in /proc/net/tcp6 as a non-root user even though my procfs is mounted with hidepid=invisible (ps
aux only shows my processes). My system is Gentoo Linux with kernel 6.1.69. Peeking at the source, it looks like
oidentd indeed reads from /proc/net/tcp6. I run oidentd on a system with hidepid=invisible and oidentd runs as a
separate oidentd user and does work (tested by trying to connect to an IrcNet server)....

Re: darkhttpd: timing attack and local leak of HTTP basic auth credentials nightmare . yeah27 (Jan 24)
Do not the various implementations of the *ident* protocol (example: oidentd)
rely on this interface? They are often, or always, intentionally configured
to run as nobody or a dedicated UID.

CVE-2023-50944: Apache Airflow: Bypass permission verification to read code of other dags Ephraim Anierobi (Jan 24)
Severity: low

Affected versions:

- Apache Airflow before 2.8.1

Description:

Apache Airflow, versions before 2.8.1, have a vulnerability that allows an authenticated user to access the source code
of a DAG to which they don't have access. This vulnerability is considered low since it requires an authenticated user
to exploit it. Users are recommended to upgrade to version 2.8.1, which fixes this issue.

metadata without any encryption. Additionally, if used with an...

Re: darkhttpd: timing attack and local leak of HTTP basic auth credentials Johannes Segitz (Jan 24)
I agree with you. Unfortunately this is next to impossible based on my
experience. We can get something like this into "hardened" configurations,
but enabling this in the default configuration will not work as there are
always (important) customers that will not accept it.

I believe we'll have to live with these issues for a long time :(

Johannes

Re: darkhttpd: timing attack and local leak of HTTP basic auth credentials Hanno Böck (Jan 23)
I'd like to comment on that.
While "on Linux" *in most distros default settings* this is true, the
Linux Kernel actually has a mitigation for this since quite a while.

This is a feature that I believe was initially introduced by
grsecurity, but was lated ported as an option to the mainline kernel.
/proc can be mounted with the hidepid option (ideally set to hidepid=2)
[1], with it enabled users cannot see processes of other users....

My first experience with Postfix was installing and running it on Red Hat 5 (or maybe it was 6) in 1998 or 1999; it

It looks like not much has changed in the intervening... wow, 25 years.

Re: Networks ignoring prepends? Chris Adams (Jan 24)
The basic disconnect here is that you seem to think that BGP is to be
used to dictate policy to other networks on how to reach your network.
That is not and has never been the case.

When I learned BGP back in the 1990s, it was explicitly said that you
control your outbound traffic with your BGP policy, but that all you can
do is try to influence the decisions of other networks for your inbound
traffic (using a combination of prepends,...

Re: Networks ignoring prepends? James Jun (Jan 24)
Nope. Your allegation that Lumen (Centurylink)'s "process" is out-out like a spammer is factually and historically
incorrect. However, Lumen's practice is complaint with best common practices and experiences as documented on RFC 4277
and provided by RFC 4271.

Lumen/Centurylink's alleged "opt-out spamming" practice predates their very existence and was established during the
NSFNET, with an operational need...

Re: One Can't Have It Both Ways Re: Streamline the CG-NAT Re: EzIP Re: IPv4 address block Abraham Y. Chen via NANOG (Jan 24)
Hi, Owen:

0)    I am glad that you do not object to the notion that two premises
on an RAN can establish end-to-end connectivity via L2 routing.

Re: Networks ignoring prepends? William Herrin (Jan 24)
What you're calling context, I call deceptive.

For one thing, Centurylink's process is, like a spammer, opt-out
rather than opt-in. 3356 enables the local pref unless told through a
BGP community not to. There's no evidence that 47787 even knows that
Centurylink is preferring them despite shorter AS paths elsewhere, let
alone desires that behavior. Indeed, given the prepends that 47787
added, it's quite possible they desire...

Re: Networks ignoring prepends? James Jun (Jan 24)
Again you omit context.

We've already established as per the RFC, that calculation of degree of preference takes precedence over and overrides
AS_PATH (Phase 1 decision).

Therefore, let's rephrase what you've just said above:

You're buying IP transit from 3 providers, two of which are configured with the following known constraints:

- 20473 who buys from 1299, who has lower degree of preference into 3356, as 1299 and...

Re: Networks ignoring prepends? William Herrin (Jan 24)
Sophistry. I buy IP transit from 3 providers, one of which has a 3 AS
path to 3356.

-Bill

Re: Networks ignoring prepends? James Jun (Jan 24)
[ snip ]

This cuts both ways Bill. First, 3356 is making an intended route selection, their customer who interconnects directly
into 3356 demands this. That customer who connects into 3356 probably had no idea that you (AS11875) would someday
decide to take IP transit from a downstream AS of them, and your situation was likely never in their minds of
consideration in their network planning.

_You_ want better connectivity from 3356 to 11875...

Re: Networks ignoring prepends? William Herrin (Jan 24)
Phase 1 is local pref. That's what 9.1.1 says. As implied by the word
"local," it's set locally by the local operator, not by the origin,
though many providers offer haphazard mechanisms that sometimes have
some impact if the origin doesn't mind playing whack-a-mole with BGP
communities.

Unless locally configured to selectively change the local pref off the
default, all routes have the same local pref. So it moves to...

Re: Networks ignoring prepends? Owen DeLong via NANOG (Jan 24)
Better is in the eye of the beholder. From your perspective, better is the lowest latency. From almost any ISPs
perspective, better is the revenue positive path, followed by the revenue neutral path, with last choice being the
revenue negative path.

From 3356 perspective, they ARE choosing the best route… the route that pays them.

Owen

Re: Networks ignoring prepends? William Herrin (Jan 24)
To be clear, I don't really care whether you're "breaking the rules."
Moreover, if my words suggested that I thought using BGP's local pref
capability was "breaking the rules," then either you misunderstood me
or I chose my words poorly. What I did say, and stand behind, was that
applying local prefs moves BGP's route selection off the _defaults_,
and if Centurylink was routing to me based instead on the...

What we really need is a way to detect invasive containers and BSDjails and have them part of appID. Some containers
are sitting and data marshaling the Network cards. I saw one a year ago that when I got access to the container and
could see it the thing self deleted.

Yeah you can check this out… pf can do os detect and it can spot a docker container with bleeding edge Kali running
inside of it.

AppID is open source, detection can be written for it.

Re: snort_ddos.rules and snort_dos.rules Joel Esler via Snort-sigs (Jan 19)
Not sure that’s something you could detect with a network product?

Re: snort_ddos.rules and snort_dos.rules Joel Esler via Snort-sigs (Jan 18)
Yes. In fact, I depreciated them when I was still at Sourcefire (before we were purchased by Cisco!). There hasn't
been anything in those categories for years. If you want DDOS/DOS rules, you need to look at the classification in the
rules for denial-of-service.

Are these two rules deprecated ? I see them as options if Snort/PFSense but when enabled no rules are displayed (active
or disabled). I also checked the snortrules-snapshot-31470.tar.gz and could not find these rules either.

Thank you

Custom Rule for blocking and NOT KILLING a specific GID:SID while KILLing all others matthew wayne oliver via Snort-sigs (Jan 08)
Hi, I would like to create a custom rule for my WAN and/or LAN to do the following: block BPFdoor magic packets,
without killing them - while having kill states enable for all other blocked rules.

The reason is it kills my World of Warcraft game if i use kill states for BPFdoor rules, which led me to FORCE DISABLE
them so as to get the alerts that might otherwise be suppresed. thank you. matthew ~

Re: Signatures detecting PHP backdoor traffic Todor P. via Snort-sigs (Jan 08)
The function vksXJAdk is defined to perform a simple XOR decoding of a
given string using a provided key.

The variable $i contains an encoded string, and the function vksXJAdk is
used to decode it using the key $eByjoghUea. The result is stored in the
variable $k.

Another encoded string is stored in the variable $j, and it is also decoded
using the same vksXJAdk function with the key $eByjoghUea. The result is
stored in the variable $f.
