VAR-202507-2463

Vulnerability from variot - Updated: 2025-08-09 23:12

A vulnerability classified as critical was found in TOTOLINK T6 4.1.5cu.748. This vulnerability affects the function ckeckKeepAlive of the file wireless.so of the component MQTT Packet Handler. The manipulation leads to command injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of t6 The firmware contains injection and command injection vulnerabilities.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK T6 is a wireless dual-band router released by China's Jiong Electronics (TOTOLINK). It supports the MQTT protocol and Telnet service.

The TOTOLINK T6 has a command injection vulnerability caused by the ckeckKeepAlive function in the wireless.so file failing to properly sanitize special characters and commands in constructed commands. No detailed vulnerability details are currently available
