VAR-201709-0364
Vulnerability from variot - Updated: 2025-04-20 20:32The AT&T U-verse 9.2.2h0d83 firmware for the Arris NVG599 device, when IP Passthrough mode is not used, configures WAN access to a caserver https service with the tech account and an empty password, which allows remote attackers to obtain root privileges by establishing a session on port 49955 and then installing new software, such as BusyBox with "nc -l" support. AT&T U-verse The firmware contains a vulnerability involving the use of hard-coded credentials.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. AT&T U-verse Arris Modems are prone to following security vulnerabilities: 1. An Hardcoded Credential Security Bypass vulnerability. 2. An information-disclosure vulnerability 3. A command injection vulnerability 4. A security-bypass vulnerability Attackers can exploit these issues to obtain sensitive information, execute arbitrary code and perform unauthorized actions., which may aid in further attacks. Failed exploit attempts may result in a denial-of-service condition. Arris NVG599 is a router product of American Arris Group Company. AT&T U-verse is the firmware used in it
