CVE-2025-4660Public exploitNetwork attack vector

SYSTEM code execution via remotely accessible named pipe

Published May 13, 2025 · Updated Aug 21, 2025

Remote code execution in Forescout SecureConnector 11.1.02.1019 through 11.3.6 allows remote authenticated users to run code as SYSTEM. The Windows agent exposes the _FS_SC_UNINSTALL_PIPE named pipe to Everyone and accepts a redirect command that sets an attacker-controlled server and an all-zero certificate thumbprint. Low-privileged network access is sufficient to bypass certificate pinning, make the agent trust the rogue server, and execute its commands with SYSTEM privileges.
