This affects the function system of the file /bin/ioos of the component WireGuard CLI Group Handler. Such manipulation of the argument group_name leads to os command injection. The attack may be performed from remote. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure.","cvssScore":10,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-77","CWE-78"],"vendors":[],"products":[],"references":[{"url":"https://github.com/senxitoyshuyi-ui/HACKALL/blob/main/WAVLINK_WN551X3-A%20Router/WAVLINK_WN551X3-A_wireguard_cli_group_command_injection.md","tags":[]},{"url":"https://vuldb.com/cve/CVE-2026-120344","tags":[]},{"url":"https://vuldb.com/submit/919551","tags":[]},{"url":"https://vuldb.com/vuln/429669","tags":[]},{"url":"https://vuldb.com/vuln/429669/cti","tags":[]}],"exploitRefs":[{"url":"https://github.com/senxitoyshuyi-ui/HACKALL/blob/main/WAVLINK_WN551X3-A%20Router/WAVLINK_WN551X3-A_wireguard_cli_group_command_injection.md","tags":[]}],"hasPoc":true,"ai":{"summary":"The WAVLINK WN551X3-A device's WireGuard CLI handler in /bin/ioos allows remote OS command injection via manipulation of the 'group_name' argument to the 'system' function, enabling full system compromise.","exploitability":"Exploitation is straightforward and requires only network access; no authentication or user interaction is needed.","blast_radius":"Successful exploitation grants attackers full remote control of the device, potentially enabling lateral movement, data exfiltration, or use as a pivot point in broader attacks.","remediation":"Upgrade to firmware version M51X3_V251020-WO-182e965-patched or later if available; otherwise, disable the WireGuard CLI functionality and restrict network access to the management interface until a patch is applied.","detection":"Look for unexpected calls to /bin/ioos with suspicious 'group_name' parameters containing shell metacharacters (e.g., ';', '|', '$(', backticks) in system logs or debug output from the device; also monitor for outbound connections to non-standard ports or unusual DNS requests originating from the device after such log entries.","tags":["rce","command-injection","wireguard","embedded-device","iot","os-command-injection"],"model":"garnet-coder","analyzedAt":"2026-11-02T09:46:52.665Z"}}
