Unauthenticated code execution via upgrade_info buffer overflow
Published Mar 9, 2022 · Updated Aug 4, 2024
Buffer overflow in TP-Link WR-886N 20190826 2.3.8 allows remote attackers to execute arbitrary code via a crafted upgrade_info POST request. The /cloud_config/router_post/upgrade_info handler copies attacker-controlled request data without adequate bounds checking. No authentication or user interaction is required, and successful exploitation permits code execution on the router.
