CVE-2024-25626Network attack vector

Unauthenticated shell command execution via crafted requests

Published Feb 19, 2024 · Updated Aug 28, 2024

OS command injection in BitBake Toaster before 2.6.2 allows remote attackers to execute shell commands via crafted HTTP requests. The Toaster server fails to validate HTTP request data before it reaches a server shell command; the parameter, handler, and command construction are undisclosed. Exposure requires the optional Toaster web interface to be running, ordinary BitBake command-line builds do not start it, and no authentication is required.
