VAR-202509-0010

Vulnerability from variot - Updated: 2025-09-10 23:30

A flaw has been found in TOTOLINK A702R 4.0.0-B20211108.1423. Affected by this issue is the function sub_419BE0 of the file /boafrm/formIpQoS. This manipulation of the argument mac causes buffer overflow. The attack can be initiated remotely. The exploit has been published and may 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 parameter mac in the file /boafrm/formIpQoS. This vulnerability could allow an attacker to execute arbitrary code on the system or cause a denial of service
