CVE-2026-34793

moderate-risk
Published 2026-04-02

Endian Firewall version 3.3.25 and prior allow authenticated users to execute arbitrary OS commands via the DATE parameter to /cgi-bin/logs_firewall.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.
