CVE-2025-1127Network attack vector

Code execution via path traversal and symlink race

Published Feb 13, 2025 · Updated Feb 13, 2025

Path traversal and a race condition in Lexmark printer firmware allow attackers to execute code and modify filesystem data. The embedded web server uses an unvalidated PATH_TRANSLATED value in basic_auth.cgi file operations, while httpd follows an attacker-created symbolic link to create an arbitrary file. Network-adjacent access requires no authentication for the traversal path, while the symlink path requires low-privileged code execution and can execute code as root.
