VAR-201709-0363
Vulnerability from variot - Updated: 2023-12-18 13:14The AT&T U-verse 9.2.2h0d83 firmware for the Arris NVG589 and NVG599 devices, when IP Passthrough mode is not used, configures ssh-permanent-enable WAN SSH logins to the remotessh account with the 5SaP9I26 password, which allows remote attackers to access a "Terminal shell v1.0" service, and subsequently obtain unrestricted root privileges, by establishing an SSH session and then entering certain shell metacharacters and BusyBox commands. AT&T U-verse The firmware contains a vulnerability related to access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. ArrisNVG589 and NVG599 are router products of Arris Group of the United States. AT&TU-verse is the firmware used in it. A security vulnerability exists in the AT&TU-verse9.2.2h0d83 version of ArrisNVG589 and NVG599. AT&T U-verse Arris Modems are prone to following security vulnerabilities: 1. 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
