Description
Endian Firewall version 3.3.25 and prior allow authenticated users to execute arbitrary OS commands via the DATE parameter to /cgi-bin/logs_log.cgi. The DATE parameter value is used to construct a file path that is passed to a Perl open() call, which allows command injection due to an incomplete regular expression validation.
Analysis
Remote code execution in Endian Firewall 3.3.25 and earlier allows authenticated attackers with low-level privileges to execute arbitrary OS commands via command injection in the DATE parameter of /cgi-bin/logs_log.cgi. The vulnerability stems from incomplete regular expression validation in Perl open() file path handling. …

Remediation
Within 24 hours: Identify all Endian Firewall instances running version 3.3.25 or earlier via asset inventory; restrict network access to /cgi-bin/logs_log.cgi to trusted administrative networks only via firewall rules or WAF policies; review authentication logs for suspicious low-privilege account activity. Within 7 days: disable the logs interface entirely if operationally feasible; rotate credentials for all low-privilege accounts with firewall access; implement enhanced monitoring on firewall configuration and command execution logs. …
