Technical details

A cross-site request forgery (CWE-352) vulnerability exists in multiple Contec products including the PC-HELPER series and CONPROSYS series. The vulnerability allows an attacker to craft a malicious webpage that, when viewed by a user already logged into an affected Contec product, will cause the victim's browser to send authenticated requests on the attacker's behalf. The attack requires user interaction (visiting a malicious page while authenticated) but no special privileges. An attacker can perform any action that the logged-in user is authorized to perform, potentially including system configuration changes, data manipulation, or network topology modifications.
