Vulnerability from fkie_nvd - Published: 2026-05-28 03:16 - Updated: 2026-10-26 12:10

Severity

8.5 (High) - CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Summary

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.

Esto permite a cualquier usuario local autenticado conectarse y enviar comandos. Debido a que el servicio no verifica los privilegios del llamador antes de ejecutar comandos de eliminaci\u00f3n de archivos, un usuario local con pocos privilegios puede explotar esto para eliminar archivos arbitrarios con autoridad de sistema."
