Summary

A pre-authentication stack-based buffer overflow vulnerability exists in the http_gdpr_decrypt function of TL-MR100 V3.20 due to insufficient bounds checking of encrypted requests to the /cgi/login endpoint. An adjacent unauthenticated attacker with access to the router's web management interface can trigger memory corruption and potentially achieve arbitrary code execution. Successful exploitation can overwrite saved control-flow data on the httpd process stack prior to authentication, resulting in a service crash or potential arbitrary code execution in the context of the affected process.

Risk Assessment

An attacker could take control of the router or cause it to crash, potentially leading to network security compromise and traffic interception.

Recommendation

Upgrade the TL-MR100 router firmware to the latest patched version. Restrict access to the web management interface and change default passwords.
