Technical details

An OS command injection vulnerability exists in the OpenVPN module of the TP-Link Archer AX53 v1.0 router. The flaw is caused by insufficient input validation when processing OpenVPN configuration files during a configuration restore process. Specifically, parameters such as 'client_connect', 'script_security', 'client_disconnect', and 'route_up' can be manipulated to execute arbitrary system commands. An attacker must be authenticated and located on the adjacent network to exploit this vulnerability. Successful exploitation allows for full system compromise, including the ability to modify configuration files and disclose sensitive information. The issue is resolved in firmware version 1.7.1 Build 20260213.
