Technical details

An external configuration control vulnerability (CWE-15/CWE-610) exists in the OpenVPN module of the TP-Link Archer AX53 v1.0 router. The flaw is triggered when the device processes a specially crafted malicious configuration file during a configuration restore or setup process. An authenticated attacker located on the adjacent network (local LAN) can exploit this to perform arbitrary file reads from the underlying filesystem. This could result in the disclosure of sensitive system files or credentials. The issue is resolved in firmware version 1.7.1 Build 20260213 and later.
