A fix is available — apply it.

luci-app-openvpn fails to properly validate the instance_name2 parameter during file upload, allowing authenticated users to perform path traversal and write arbitrary files outside the intended directory. Attackers can upload malicious payloads to gain persistent root code execution by placing SSH keys in system directories accessible on reboot.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
