NitroSense V3: Security Vulnerability Information

State: Published
Severity: 8.5 High
Published: May 28, 2026
Updated: May 28, 2026
Reserved: May 28, 2026

Description

A Local Privilege Escalation (LPE) vulnerability affects Acer NitroSense software versions prior to 3.01.3052. The vulnerability stems from the the PSAdminAgent service, which creates a Named Pipe with a weak Access Control List (ACL). This allows any authenticated local user to connect and send commands. Because the service does not check the caller's privileges before running file deletion commands, a low-privileged local user can exploit this to delete arbitrary files with system authority.
