Authenticated command execution via DATE path injection
Published Apr 2, 2026 · Updated Apr 2, 2026
OS command injection in Endian Community Firewall 3.3.25 and earlier allows remote authenticated users to execute arbitrary commands. The logs_log.cgi handler builds a file path from the DATE parameter and passes it to Perl open after an incomplete regular-expression check. Access to the authenticated management endpoint is required, and successful exploitation permits command execution on the firewall host.
