## Technical details

A Cross-Site Request Forgery (CSRF) vulnerability exists in the web management interface of Technostrobe HI-LED-WR120-G2 firmware version 5.5.0.1R6.03.30. The flaw stems from missing authorization checks and a lack of anti-CSRF tokens in an unspecified function. A remote attacker can exploit this by inducing an authenticated user to submit a specially crafted web request. Successful exploitation allows the attacker to perform state-changing operations with the privileges of the victim. A public exploit (PoC) has been released, and the vendor has reportedly not responded to disclosure attempts.
