Executive Summary

CVE-2025-58455 is a heap-based buffer overflow vulnerability found in the TP-Link Archer AX53 v1.0 router, specifically within the tmpserver module.

This vulnerability occurs when an authenticated adjacent attacker sends a specially crafted network packet with a packet length exceeding the maximum expected limits.

The improper handling of this oversized packet length can cause a segmentation fault, potentially allowing the attacker to execute arbitrary code on the device.

Impact Analysis

This vulnerability can lead to a segmentation fault, which may cause the device to crash or become unstable.

More critically, it potentially allows an attacker to execute arbitrary code on the affected router, which could lead to unauthorized control over the device.

Such control could compromise the confidentiality, integrity, and availability of the network and data passing through the router.

Detection Guidance

This vulnerability involves an authenticated adjacent attacker sending a specially crafted network packet with a length exceeding the maximum expected value to the TP-Link Archer AX53 v1.0 tmpserver module. Detection would involve monitoring for unusual or oversized network packets targeting this device.

However, no specific detection commands or tools are provided in the available resources.

Mitigation Strategies

Users are strongly advised to update the firmware of the TP-Link Archer AX53 v1.0 router to the latest version, specifically to versions beyond V1_260119, as this update addresses the heap-based buffer overflow vulnerability in the tmpserver module.

Compliance Impact

The CVE-2025-58455 vulnerability involves a heap-based buffer overflow that can lead to arbitrary code execution, impacting the confidentiality, integrity, and availability of the affected TP-Link Archer AX53 device.

Such impacts on confidentiality, integrity, and availability could potentially affect compliance with common standards and regulations like GDPR and HIPAA, which require protection of sensitive data and system integrity.

However, the provided information does not explicitly describe how this vulnerability directly affects compliance with these standards or regulations.
