VAR-202509-0188

Vulnerability from variot - Updated: 2025-09-27 23:37

A vulnerability was found in TOTOLINK A702R 4.0.0-B20211108.1423. This vulnerability affects the function sub_4466F8 of the file /boafrm/formOneKeyAccessButton. Performing manipulation of the argument submit-url results in buffer overflow. The attack may be initiated remotely. The exploit has been made public and could be used. TOTOLINK of A702R The firmware contains a buffer error vulnerability and a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK A702R is a wireless router manufactured by China's TOTOLINK Electronics, primarily used for home network connectivity and signal coverage.

The TOTOLINK A702R suffers from a buffer overflow vulnerability caused by a failure to properly validate the length of input data in the submit-url parameter in the file /boafrm/formOneKeyAccessButton. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service
