A deep-dive into the SolarWinds Serv-U SSH vulnerability

Several weeks ago, Microsoft detected a 0-day remote code execution exploit being used to attack the SolarWinds Serv-U FTP software in limited and targeted attacks. The Microsoft Threat Intelligence Center MSTIC attributed the attack with high confidence to DEV-0322, a group operating out of Chin...

ASB-A-190188264

In RGBtoBGR1portable of SkSwizzleropts.h, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation...

Uninitialized memory exposure in claxon

Affected versions of Claxon made an invalid assumption about the decode buffer size being a multiple of a value read from the bitstream. This could cause parts of the decode buffer to not be overwritten. If the decode buffer was newly allocated and uninitialized, this uninitialized memory could b...

WAF-A-MoLE - A Guided Mutation-Based Fuzzer For ML-based Web Application Firewalls

A guided mutation-based fuzzer for ML-based Web Application Firewalls, inspired by AFL and based on the FuzzingBook by Andreas Zeller et al. Given an input SQL injection query, it tries to produce a semantic invariant query that is able to bypass the target WAF. You can use this tool for assessin...

CVE-2021-23169

A heap-buffer overflow was found in the copyIntoFrameBuffer function of OpenEXR in versions before 3.0.1. An attacker could use this flaw to execute arbitrary code with the permissions of the user running the application compiled against OpenEXR...

Heap-based Buffer Overflow in squell/id3

✍️ Description Archive.org is a worthy cause to support. 👍 During testing of id3 compiled from commit a899ea with Clang 13+ASan on Ubuntu 20.04.2, we discovered a payload which triggers a heap-buffer-overflow in ID3put. This particular bug was found using the AFL fuzzer. 🕵️‍♂️ Proof of Concept echo...
