CVE-2026-120280 Details
Description
A vulnerability has been found in WAVLINK WN536AX6-A V260507. The impacted element is the function wireguard_cli_group handler of the file /protocol.csp of the component WireGuard. The manipulation of the argument group_id/group_name leads to os command injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure.
A command injection vulnerability has been identified in the WAVLINK WN536AX6-A router, specifically in the WireGuard component. This vulnerability exists in firmware version V260507, within the 'wireguard_cli_group' handler of the 'protocol.csp' file. The issue arises because the 'group_id' and 'group_name' parameters are not properly sanitized before being used in a shell command, allowing for arbitrary command execution. Exploitation can be done remotely, and although authentication is required, it can be easily bypassed as the device defaults to passwordless login.
