Technical details

An unauthenticated arbitrary file upload vulnerability exists in the Technostrobe HI-LED-WR120-G2 firmware version 5.5.0.1R6.03.30. The flaw is located in the '/fs' file system handler, where the 'cwd' argument can be manipulated to specify upload paths. Because the application fails to validate user authorization or restrict file types/locations, a remote attacker can upload malicious scripts or binaries to the web root. This can lead to Remote Code Execution (RCE) and full system compromise. A public exploit (PoC) is available, and the vendor has reportedly not responded to disclosure attempts.
