CVE-2024-33434Public exploitNetwork attack vector

Unauthenticated code execution via unsanitized build filename

Published May 7, 2024 · Updated Apr 3, 2026

OS command injection in CHAOS 5.0.1 allows remote attackers to execute arbitrary code through a crafted filename in a binary-generation request. BuildClient inserts the filename into the buildStr shell command without sanitization, then passes the resulting string to sh -c. The request requires no privileges or user interaction, and successful exploitation runs commands with the CHAOS server process's privileges.
