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_ids.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 command execution in Endian Firewall 3.3.25 and earlier allows authenticated attackers to execute arbitrary OS commands with firewall appliance privileges via command injection in the DATE parameter of /cgi-bin/logs_ids.cgi. The vulnerability stems from incomplete regular expression validation before passing user input to Perl's open() function. …
