DescriptionCVE.org

An OS command injection vulnerability in the OpenVPN module of TP-Link Archer AX53 v1.0 allows an authenticated adjacent attacker to execute system commands when a specially crafted configuration file is processed due to insufficient input validation. Successful exploitation may allow modification of configuration files, disclosure of sensitive information, or further compromise of device integrity.

This issue affects AX53 v1.0: before 1.7.1 Build 20260213.

AnalysisAI

OS command injection in TP-Link Archer AX53 v1.0 OpenVPN module allows authenticated adjacent attackers to execute arbitrary system commands through maliciously crafted configuration files. Exploitation requires high-privilege adjacency access but enables complete device compromise including configuration modification, credential disclosure, and persistent backdoor installation. Affects AX53 v1.0 firmware prior to 1.7.1 Build 20260213. No public exploit identified at time of analysis.

Technical ContextAI

CWE-78 command injection vulnerability stems from insufficient input sanitization in OpenVPN configuration parser. CVSS:4.0 Adjacent Vector (AV:A) with High Privileges Required (PR:H) indicates attacker must possess administrative credentials on local network segment. Unvalidated parameters passed directly to shell execution context enable command chaining via metacharacters in uploaded .ovpn configuration files.

RemediationAI

Vendor-released patch: firmware version 1.7.1 Build 20260213. Immediately upgrade to patched firmware available from TP-Link official support portal at https://www.tp-link.com/en/support/download/archer-ax53/v1/#Firmware. Interim mitigations: disable OpenVPN server functionality if not operationally required, restrict administrative interface access to trusted IP ranges via router ACLs, enforce strong WPA3 authentication on wireless networks to prevent adjacency access, monitor device logs for unauthorized configuration changes. Detailed vendor security advisory available at https://www.tp-link.com/us/support/faq/5055/. Adjacent network positioning requirement limits remote exploitation; prioritize patching in environments with untrusted local network users.
