Technical details

A stack-based buffer overflow (CWE-121) exists in the 'tdpServer' module of TP-Link Archer AX53 v1, AX55 v4, and AX55 v4.6 routers. The flaw is caused by insufficient input sanitization within the device's probe handling logic when processing unvalidated parameters. A remote, unauthenticated attacker can exploit this by sending specially crafted packets to trigger the overflow. Successful exploitation can lead to a service crash (Denial of Service) or, through complex heap-spray techniques, remote code execution. Firmware updates are available to address this issue.
