CVE-2025-34082Public exploitNetwork attack vector

Unauthenticated code execution via unsanitized PROXYCMD input

Published Jul 3, 2025 · Updated May 14, 2026

OS command injection in IGEL OS 10 before 10.06.220 and 11 before 11.04.270 allows remote attackers to execute code as root. The Secure Terminal and Secure Shadow TLS connectors pass shell metacharacters from unauthenticated PROXYCMD input into a systemd-run invocation of bash without neutralization. Exploitation requires either service to be enabled and TCP port 30022 or 5900 to be reachable; successful commands run with elevated privileges.
