SYSTEM code execution via pipe impersonation
Published Oct 28, 2021 · Updated Sep 17, 2024
Privilege escalation in Endpoint Security Tools before 7.2.1.65 and Total Security before 25.0.26 allows local users to gain SYSTEM. The Windows endpoint client permits an untrusted process to impersonate a pipe client, causing its server thread to act under an unintended security context. Low-privileged code execution on the host is required, and successful exploitation executes arbitrary code as NT AUTHORITY\SYSTEM.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
