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_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.
Analysis
Remote code execution in Endian Firewall versions ≤3.3.25 allows authenticated users with low privileges to execute arbitrary operating system commands through command injection in the logs_openvpn.cgi DATE parameter. The vulnerability stems from inadequate input validation in a Perl open() call, enabling attackers to break out of intended file path operations. …

Remediation
Within 24 hours: Inventory all Endian Firewall deployments and identify instances running version 3.3.25 or earlier; restrict network access to the logs_openvpn.cgi endpoint to trusted administrative networks only. Within 7 days: Contact Endian support for patch availability and timeline; implement role-based access controls to limit low-privilege user access to sensitive CGI interfaces; audit logs for suspicious DATE parameter submissions to logs_openvpn.cgi. …
