TIL how easy it is to ask curl to dump TLS session keys to disk 🛠️ Simply set the environment variable `SSLKEYLOGFILE=/path/to/file` 😅 Note: it also works for Firefox and Chrome Extremely useful when combined with Wireshark 👍

S2-067 is a fantastic bypass of the patch for S2-066. It uses ONGL to re-write the upload filename property in order to bypass the filename path traversal checks. PoC: if the target bean is called "UploadFile" the your target parameter is "top.UploadFileFileName". 🤯

I wrote a fun, little blog post. Remote pre-auth file deletion in SolarWinds ARM allowed to achieve LPE on AD machines 🙃

In his latest blog, @chudypb.bsky.social covers a pre-auth Arbitrary File Deletion bug he discovered in the SolarWinds Access Rights Manager (ARM). It may not sound exciting, but it can lead to an LPE on domain-joined Windows machines. Read the details at www.zerodayinitiative.com/blog/2024/12...

My latest blog post is live 🔥 Read it to learn what SafeMarshal is and *two* very different ways to escape and get RCE! Read it to find out why Date is *not* a safe class in Ruby or how to leverage serialized strings being constructed with string concatenation! nastystereo.com/security/rub...

Oh, I never posted my gotofail story on here. Early 2014, someone came to me about a catastrophic vulnerability in Apple's TLS implementation. I shit you not, they'd overheard someone at a bar drunkenly bragging about how they were going to sell it to a FVEY intelligence agency for six figures.
