Trying to talk a customer out of buying firewalls for their MPLS transport network. They'd do better to invest the time in hardening, monitoring but apparently that's too hard.

Worth noting that after that paper's release I did further work and found examples that would yield code execution and LPE.

Coding with LLMs and agents is a generational opportunity to throw the last decade's hard won lessons on secure coding and appsec out of the window. Definitely something that trust and safety teams, threat actors and possibly even your parents are seizing on with glee when they bypass all of your policies and procedures around installing new software, data governance, validated designs, code reviews, principles of least privilege and regular security assessments. Best of luck.

RE: https://infosec.exchange/@timb_machine/116068550511596363
If there's anyone on here that works at GitHub, do you think you could remind your support team to check their emails.
For reasons unknown you decided to suspend my account a week ago and I'm yet to even get a response that a ticket has been opened to investigate. I'm sure there's a reason (although I suspect it's debatable) but it would at least be nice to hear from you that it's being looked at.

*sigh*, a reminder that there are definite pros to self hosting. Waiting for someone to respond to a support ticket.

Seen an interesting trend in UK FSI over the last months, with multiple requests for specific support in hampering network-centric aspects of discovery, lateral movement, C2 and exfiltration. I wonder what it's attributed to.

Activity spinning up on GitHub for people playing with the bug, but also at least a few possibly vulnerable code bases:
https://github.com/search?q=%3Cparam-name%3Ereadonly%3C%2Fparam-name%3E+%3Cparam-value%3Efalse%3C%2Fparam-value%3E++&type=code
The author of the blog post mentioned in my previous post initially predicted KEV but then reconsidered. I suspect they're right but it will it will depend on if any big commercial J2EE is vulnerable as deployed on TomCat. To that end, the following from the VMware folks looked interesting:

Pretty sure this customer doesn't own unregistereddomain.tld. Probably not the best FQDN for their OT hosts to be authenticating against.

A bug so hard to fix that it took almost 10 years to make a decision.

Looking at legacy NeXT source:
https://github.com/johnsonjh/NeXTSrc/blob/ff846608a76ab2fbbb86e8a14c52ac85332f9786/libc-34.1/libc/gen/execvp.c#L34
Quoting from the OS X man page for execvp():
"Historically, the default path for the execlp() and execvp() functions was ``:/bin:/usr/bin''. This was changed to place the current directory last to enhance system security."

Samba can also expose your CUPS configured printers too so it's not just 631/tcp to be watchful of.

That's not typically the default but we're talking about something that is fundamentally designed to be a server & queue manager for others on the network. By default, cupsd (the actual server & queue manager) may well be bound to localhost, with browsing set to no and various IPP API endpoints restricted with location ACLs but all of these can and are changed for various reasons (witness 631/tcp being open).

The *victim needs to print* narrative would be fine if we're targetting an end user. Thing is, we're not - we're targetting the print server.

2024-09-28 07:42:07 UTC

Casual observation. *Someone* needs to print something. What happens if the adversary can?

Rumours look to have been accurate, it looks like it's CUPS:

Add in, runs as root and likely listens on the network (by default).

If you wanted to speculate on the upcoming CVE in Linux distros, correlating Popcon with those that have listening ports and CVE data might be one way to make a prediction:

PSA: Wild speculation is the best speculation.
