SYSTEM code execution via unquoted service path
Published Dec 11, 2025 · Updated Dec 11, 2025
Unquoted service path handling in AnyDesk 7.0.15 and 9.0.1 allows local users to execute code with SYSTEM privileges on Windows. Windows service configuration leaves the space-containing AnyDesk executable path unquoted, so path resolution can select an attacker-planted executable before the intended binary. Exploitation requires local access and permission to write an executable into an earlier path segment; service startup then runs that file as 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.
