Finding zero-day is great and all, but I really love finding bugs that were silently patched. Less disclosure work and often just as much impact.
PS. Using Ruckus Wireless APs? _Definitely_ apply the latest firmware (5.2.1 or newer).

I mean, that's one way to drive FOMO. Thanks vendor!

The #golang `gorilla/sessions` directory traversal and file (over)write is now being tracked as GO-2024-2730: https://go-review.googlesource.com/c/vulndb/+/579655
This issue was (co)-discovered as part of watchTowr's analysis of the Palo Alto Networks RCE (#CVE_2024_3400), but is entirely separate, and affects a wide range of Go-based web services.
https://github.com/golang/vulndb/issues/2730
If you use gorilla/sessions with the FilesystemStore, please switch to the CookieStore instead until a patch is available.
Huh. So the Gorilla project went into archive-only mode in 2022. The gorilla/sessions project opened an issue asking for a new maintainer, this issue was closed as "stale", and a final comment was added indicating that the project is archived: https://github.com/gorilla/sessions/issues/250
The Gorilla project website, however, states that as of July 2023, a new maintainer has been identified, and the gorilla/mux project is seeing recent commits, so hopefully the same maintainers are also managing gorilla/sessions. The gorilla/sessions CI automation is failing with a bad credential and it looks like the sessions project specifically hasn't seen much love lately. #golang #vulnerability
Looks like quite a few projects are using session.FilesystemStore: https://github.com/search?q=sessions.NewFilesystemStore+language%3Ago+&type=code
The watchTowr folks published an in-depth article today covering the Palo Alto Networks unauthenticated RCE at: https://labs.watchtowr.com/palo-alto-putting-the-protecc-in-globalprotect-cve-2024-3400/
Even more impressive is they also disclosed a zero-day directory traversal vulnerability in the #golang gorilla/sessions package (used far and wide). The gorilla vulnerability only applies to code using the FilesystemStore, but it is still likely to impact a huge range of products and services. A pull request to fix this is open at https://github.com/gorilla/sessions/pull/274
Huge thanks to @alizthehax0r and the watchTowr team as well as @moloch of Bishop Fox for co-discovery (and providing a fix for) of the gorilla/sessions bug.
Thank you @CypherCon! What an amazing event and a great community! Opening slides from my keynote today:
