Exploitation Summary

EIP tracks 1 public exploit for CVE-2026-9789. PoCs published by ugvxb.

AI-analyzed exploit summary The repository contains a functional exploit for CVE-2026-9789, demonstrating arbitrary file deletion via a weakly secured named pipe in Acer NitroSense software. The exploit leverages insufficient ACL restrictions and lack of path validation to delete files with SYSTEM privileges.

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.
