AV:N/AC:L/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions Endian Firewall versions prior to 3.0

Description The issue is related to the lack of input validation in the Endian Firewall. It allows a remote attacker to execute arbitrary commands by passing metacharacters through the NEW PASSWORD 1 or NEW PASSWORD 2 parameters in the "cgi-bin/chpasswd.cgi" endpoint.

Recommendations For Endian Firewall versions prior to 3.0, update to version 3.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the "cgi-bin/chpasswd.cgi" endpoint to minimize the risk of exploitation. Avoid using the parameters NEW PASSWORD 1 and NEW PASSWORD 2 in the affected endpoint until the issue is resolved.
