Technical details

The port_forward function in /cgi-bin/wapi.cgi performs insufficient input validation on the name parameter, allowing shell metacharacters like pipes and redirects to bypass a blacklist filter. The unsanitized input is concatenated into a shell command executed via popen(), enabling OS command injection. Authentication and valid session cookies are required to trigger the vulnerability.
