Buffer Overflow Vulnerability in TP-Link AX53

Assigner: TPLink
Reserved: 05.03.2026 Published: 08.04.2026 Updated: 09.04.2026

A stack-based buffer overflow in the tmpServer module of TP-Link Archer AX53 v1.0 allows an authenticated adjacent attacker to trigger a segmentation fault and potentially execute arbitrary code via a specially crafted configuration file. Successful exploitation may cause a crash and could allow arbitrary code execution, enabling modification of device state, exposure of sensitive data, or further compromise of device integrity.

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