TP-Link CVE-2023-50224 authentication flaw, EOL devices, and mitigation

Vulnerability Overview Vulnerability ID: CVE-2023-50224 Vulnerability Type: Authentication flaw in the HTTP service. Impact: Allows an attacker in a network-adjacent position to obtain sensitive information. Risk: May lead to credential leakage, potentially resulting in session hijacking. The vulnerability has been observed to be actively exploited in the wild, including attack campaigns involving DNS manipulation. Scope of Impact Affected Products: Multiple legacy TP-Link routers and access points. Status: The affected products have reached End-of-Life (EOL) status and are no longer within TP-Link's standard maintenance scope. Affected Models (partial list): Routers: TL-MR6400, Archer C5, Archer C7, Archer C1900, TL-WDR300, TL-WDR350, TL-WR710N, TL-WR740N, TL-WR741ND, TL-WR742N, TL-WR743N, TL-WR745N, TL-WR841N, TL-WR842N, TL-WR843N, TL-WR845N, TL-WR902AC, TL-WR940N, TL-WR940N Plus, TL-WR941HP, TL-WR941ND, TL-WR945N, TL-MR3020, TL-MR3220, TL-MR420. Access Points: TL-WA701ND, TL-WA901ND, TL-WA901N. Remediation Status: Some legacy products have received technical support for secured versions (status marked as Patched or Partially patched). Due to hardware constraints, outdated platforms, or lack of available technology, not all legacy products can be patched (status marked as Unpatched). Some models support cloud-based or automatic firmware updates, while others require manual installation. Remediation and Recommendations Upgrade: It is strongly recommended to immediately upgrade affected or potentially affected legacy devices to supported TP-Link products that receive regular security updates. Mitigations (if continued use of legacy devices is unavoidable): 1. Install the latest available firmware from the TP-Link official website. 2. Disable remote administration and unnecessary services. 3. Restrict remote access to trusted internal networks. 4. Monitor network activity for abnormal DNS behavior or unauthorized configuration changes. Disclaimer: Affected products are in EOL status; customers are required to assess the risk themselves and take appropriate measures. TP-Link strongly recommends migrating to supported products.
