Summary
Endian Firewall version 3.3.25 and earlier allows authenticated users to execute arbitrary OS commands via the DATE parameter in /cgi-bin/logs_openvpn.cgi. The parameter value is used to build a file path passed to Perl's open() function, enabling command injection due to incomplete regex validation.
Risk Assessment
An authenticated attacker could gain full control of the firewall server by executing arbitrary commands, leading to complete system compromise.
Recommendation
Upgrade Endian Firewall to a version later than 3.3.25 that includes proper validation of the DATE parameter.

Original NVD description (English source)
Endian Firewall version 3.3.25 and prior allow authenticated users to execute arbitrary OS commands via the DATE parameter to /cgi-bin/logs_openvpn.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.
