CVE-2022-30580

Arbitrary code execution via empty executable path

Published Aug 9, 2022 · Updated Mar 6, 2026

Code injection in Go standard library os/exec before 1.17.11 and 1.18.0-0 before 1.18.3 allows local users to execute binaries on Windows. Cmd.Start proceeds with an empty Cmd.Path instead of rejecting it, causing Windows to launch a working-directory file named ..com or ..exe. Exploitation requires local control of that specially named file and execution of Run, Start, Output, or CombinedOutput with Path unset.
