Local socket reachable by any unprivileged local user (AV:L/PR:N/UI:N); missing auth grants control functionality yielding limited disclosure but high integrity/availability impact on system state.

Lifecycle Timeline
2DescriptionCVE.org
A vulnerability has been identified in the Acer Agent Service component included with NitroSense and PredatorSense. The socket handshake process does not properly require authentication before granting access to the service. Under certain circumstances, an unauthorized connection may be established, potentially allowing access to functionality that should be restricted.
AnalysisAI
Local unauthenticated access to the Acer Agent Service - the background component shipped with Acer's NitroSense and PredatorSense utilities on Nitro and Predator Windows laptops - allows any user or piece of malware already running on the host to open a connection to the service socket and reach functionality that should be restricted, because the socket handshake never verifies the caller's identity (CWE-306). Rated CVSS 4.9 (CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:H) and scored by our assessment as CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H, the flaw is not remotely reachable and requires the Acer software to be installed, with the vendor description noting the unauthenticated handshake path succeeds only 'under certain circumstances.' No public exploit has been identified at time of analysis, and the practical exposure is a local privilege/functionality boundary bypass rather than an internet-facing emergency.
