I'm glad to announce that - probably as a result of careful shitposting yesterday - Nicole, the Fediverse Chick noticed me!

Ivanti CVE-2025-22457 is being exploited ITW.
https://forums.ivanti.com/s/article/April-Security-Advisory-Ivanti-Connect-Secure-Policy-Secure-ZTA-Gateways-CVE-2025-22457

Per Mandiant:

We assess it is likely the threat actor studied the patch for the vulnerability in ICS 22.7R2.6 and uncovered through a complicated process, it was possible to exploit 22.7R2.5 and earlier to achieve remote code execution.

Gee, who could have imagined that attackers are looking at patches? 🤔

1) This apparently was silently fixed for ICS in 22.7R2.6, as the fix for this was released in February. Per Ivanti, the buffer overflow was considered a "product bug" at that time, as opposed to a vulnerability. Ivanti Policy Secure and ZTA gateways are expected to receive a patch in late April.

2) The advisory still conveys the magical thinking if if your device shows signs of compromise, then you should perform a "factory reset." This is magical in that the ICT won't catch a compromise nor will the "factory reset" reset to factory condition if the attacker is bothering to try.

While Mandiant also parrots the magical thinking of running the ICT tool, which I guess is the best advice if you're not going to throw the device in the trash since there isn't an official integrity checking tool that is sound, they do throw out a tidbit of:

... and conduct anomaly detection of client TLS certificates presented to the appliance.

Bets on whether CVE-2025-22457 is an overflow in the handling of a field in a client-provided certificate? 😂

"Our belief is that it's highly impractical to exploit on 64-bit systems
where xz was built with PIE (=> ASLR), but that on 32-bit systems,
especially without PIE, it may be doable."

#NoCVE

I'm sad to say that we're following the lead of many others and putting in proof-of-work proxies into place to protect ourselves against "AI" crawler bots. Yes, I hate this as much as you, but all other options are currently worse (such as locking us into specific vendors).

We'll be rolling it out on lore.kernel.org and git.kernel.org in the next week or so.

Another day, another bug...

In 2020, I solved a gnarly reverse engineering challenge in PlaidCTF. Only 9 teams solved.

It's a huge pile of Typescript. Everything is named after a fish.

The catch? There's no code, only types. How do they perform computation using just the type system?

LLM use case: as "github syntax highlighter" doesn't give very good results when I try to find out what GitHub specifically uses, I turned to FastGPT.

Its answer ("Tree-sitter grammars are used for syntax highlighting") was wrong, while pointed to the correct SO answer (pointing to Linguist) as a reference:
