Executive Summary

This vulnerability occurs in the TP-Link Archer BE230 v1.2 router where an authenticated user with high privileges can cause a denial-of-service (DoS) condition. This happens by restoring a specially crafted configuration file that contains an excessively long parameter. When this file is restored, the device becomes unresponsive and requires a reboot to return to normal operation.

Impact Analysis

The impact of this vulnerability is that an attacker with high privileges can make the TP-Link Archer BE230 device unresponsive by restoring a malicious configuration file. This denial-of-service condition disrupts normal device operation and requires a manual reboot to recover, potentially causing downtime and loss of network availability.

Mitigation Strategies

To mitigate this vulnerability, ensure that your TP-Link Archer BE230 device is updated to version 1.2.4 Build 20251218 rel.70420 or later.

Avoid restoring configuration files that are not verified or that may contain excessively long parameters, as this can trigger a denial-of-service condition.

If the device becomes unresponsive due to this issue, a reboot is required to restore normal operation.
