Assigner: TPLink

Description
Heap-based Buffer Overflow vulnerability in TP-Link Archer AX53 v1.0 (tmpserver modules) allows authenticated adjacent attackers to cause a segmentation fault or potentially execute arbitrary code. The vulnerability arises from improper validation of a packet field whose offset is used to determine the write location in memory. By crafting a packet with a manipulated field offset, an attacker can redirect writes to arbitrary memory locations.This issue affects Archer AX53 v1.0: through 1.3.1 Build 20241120.

Executive Summary

This vulnerability is a heap-based buffer overflow found in the TP-Link Archer AX53 v1.0, specifically in the tmpserver modules. It allows an authenticated attacker on an adjacent network to cause a segmentation fault or potentially execute arbitrary code. The issue occurs because the device improperly validates a packet field that determines where data is written in memory. By crafting a packet with a manipulated field offset, the attacker can redirect memory writes to arbitrary locations.

Impact Analysis

This vulnerability can lead to a segmentation fault, causing the device to crash or become unstable. More seriously, it could allow an attacker to execute arbitrary code on the device, potentially gaining control over it. This could result in unauthorized access, disruption of network services, or further exploitation of the device within the network.
