VAR-202506-0952

Vulnerability from variot - Updated: 2025-07-04 23:42

A vulnerability, which was classified as problematic, has been found in TOTOLINK T10 4.1.8cu.5207. Affected by this issue is some unknown functionality of the file /etc/shadow.sample. The manipulation leads to use of hard-coded password. The attack can only be initiated within the local network. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. TOTOLINK of t10 The firmware contains vulnerabilities related to certificate and password management, as well as vulnerabilities related to the use of hard-coded passwords.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK T10 is a wireless network system router from China's Jiweng Electronics (TOTOLINK) company.

TOTOLINK T10 has a trust management issue vulnerability, which stems from the use of hard-coded passwords in the file /etc/shadow.sample. Attackers can exploit this vulnerability to affect confidentiality, integrity, and availability
