AI-suggested

Since the vulnerability requires code execution as LOCAL SERVICE, restricting or monitoring processes running under this account may reduce risk. Until then, limit LOCAL SERVICE privileges where possible and avoid running untrusted code with these privileges.

Description

CVE-2026-114031 is a local privilege escalation vulnerability in the Illumio VEN for Windows. It arises from incorrect permission assignments in the VEN installer, which grants the LOCAL SERVICE account full access to critical VEN data and installation folders. This allows an attacker with code execution as LOCAL SERVICE to modify VEN configuration files that are trusted by a SYSTEM-privileged component, enabling execution of arbitrary commands with SYSTEM privileges.
