Exploitation Summary
EIP tracks 1 public exploit for CVE-2009-2669. PoCs published by Marco Ivaldi.
AI-analyzed exploit summary This exploit leverages improper handling of the _LIB_INIT_DBG and _LIB_INIT_DBG_FILE environment variables in IBM AIX to create an arbitrary root-owned file with world-writable permissions via a setuid-root program linked to libC.a or libc.a. It demonstrates a local privilege escalation by overwriting sensitive files.
Description
A certain debugging component in IBM AIX 5.3 and 6.1 does not properly handle the (1) _LIB_INIT_DBG and (2) _LIB_INIT_DBG_FILE environment variables, which allows local users to gain privileges by leveraging a setuid-root program to create an arbitrary root-owned file with world-writable permissions, related to libC.a (aka the XL C++ runtime library) in AIX 5.3 and libc.a in AIX 6.1.
