Technical details
The vulnerability is an unauthenticated OS command injection in the /www/cgi-bin/network_tools CGI script, where user-supplied QUERY_STRING input is passed directly to eval() before authentication checks occur. The vulnerable code path parses URL parameters using eval without proper sanitization, as the urldecode() sanitization function is commented out. An attacker can send a crafted GET request to execute arbitrary shell commands with root privileges on the device.
