CVE-2026-120280: WAVLINK WN536AX6 OS command injection in WireGuard handler

CVE-2026-120280 · Severity: critical · CVSS 10 · Published 2026-11-02

The WAVLINK WN536AX6 router contains an OS command injection vulnerability in its WireGuard configuration interface that allows attackers to execute arbitrary commands with root privileges. The vulnerability is exploitable remotely because the device ships with passwordless login enabled by default, enabling an attacker to obtain authentication and then inject malicious commands through improperly sanitized parameters. Successful exploitation results in complete compromise of the router, exposing the corporate network it protects to takeover and data exfiltration.

Vendors: Wavlink.

Technical details

The wireguard_cli_group handler in /protocol.csp fails to sanitize the group_id and group_name parameters before passing them to a shell command executed via system(). An attacker can bypass authentication trivially via the FirstLogin=1 default setting (passwordless login) to obtain a session token, then inject shell metacharacters (e.g., '; arbitrary command #) to achieve remote code execution as root. The vulnerability requires only an unauthenticated login request followed by a crafted request to the vulnerable endpoint.
