CWE-798Published: September 3, 2017· Updated: Jun 17, 2026

8.1

CVSS v3.1

Official Description

The 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.

Technical Analysis

CVE-2017-14115 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.1.
