VAR-202507-2447

Vulnerability from variot - Updated: 2025-08-06 23:12

A vulnerability, which was classified as critical, has been found in TOTOLINK T6 4.1.5cu.748_B20211015. This issue affects the function recvSlaveUpgstatus of the component MQTT Service. The manipulation of the argument s leads to buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of t6 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 T6 is a wireless dual-band router released by China's TOTOLINK Electronics. It supports the MQTT protocol and Telnet service, and is primarily designed for home and small business networking. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service
