Unauthenticated command execution via crafted fax filename
Published May 23, 2025 · Updated May 23, 2025
OS command injection in Fujian Kelixun 1.0 allows remote attackers to execute arbitrary system commands through a crafted fax filename. The /app/fax/fax_view.php endpoint places the attacker-controlled fax_file filename into a system command without validation or neutralization. No authentication is required, and successful exploitation grants command execution in the server application's context.
