Executive brief
Acer Agent Service, a component bundled with gaming and performance software (NitroSense and PredatorSense), contains a flaw in its socket authentication mechanism. An attacker could establish an unauthorized connection and access restricted service functionality without credentials, potentially leading to privilege escalation or system compromise.
Technical details
The vulnerability is an authentication bypass in the socket handshake process of Acer Agent Service. The service fails to properly validate or require authentication credentials before granting access to socket connections, allowing an unauthorized local or network connection to access restricted functionality. An attacker with local network access or code execution on the system could exploit this to interact with the service and perform privileged operations. The attack vector is network or local, and no user interaction is required once a connection is established.
