CVE-2026-120238Network attack vector

Command execution via ovpn_file file_id injection

Published Nov 1, 2026 · Updated Nov 1, 2026

Command injection in Wavlink Technology Ltd. HALO AIR 260403_2.0.0 allows remote attackers to execute commands via file_id. The ovpn_file handler's sub_4162A8 function in /bin/ioos processes the attacker-controlled argument unsafely; the exact command construction is not available in the retrieved disclosure. Exploitation requires network reachability to the handler, but authentication requirements and execution privileges remain unspecified.
