Remote command injection in DD-WRT httpd management GUI (cgi-bin/ URI)
DD-WRT’s embedded web server (httpd) used by the management GUI contains an OS command injection flaw in versions 24 sp1 and other releases prior to build 12533. The vulnerable request handling for cgi-bin/ URIs fails to properly sanitize user-supplied input, allowing shell metacharacters to be interpreted by the underlying system shell. A remote attacker can send a crafted HTTP request to a cgi-bin/ endpoint and inject arbitrary commands for execution on the device.
