CVE-2022-2147

Privilege escalation via unquoted service path

Published Jun 23, 2022 · Updated Aug 3, 2024

Privilege escalation in Cloudflare WARP for Windows allows local users to execute arbitrary code through an unquoted service path. A Windows service registration stores its executable path without surrounding quotation marks, allowing path parsing to select an attacker-planted executable. Exploitation requires write access to a probed parent path and execution occurs when the privileged service starts.
