What to do

AI-suggested

Organizations should verify the firmware version of their AdTran SRG 834-5 devices and ensure they are running SmartOS version 12.1.3.1 or later, where this vulnerability is fixed. During device setup, restrict SSH access to trusted management networks only, ideally disabling WAN access entirely until the device is fully configured. Change default credentials immediately upon initial access and enforce strong password policies. Implement network segmentation to isolate management interfaces from general user networks and the Internet. Monitor device logs for unauthorized access attempts during the setup phase. If possible, disable SSH during setup or use out-of-band management methods to reduce exposure. Maintain an inventory of affected devices and apply vendor advisories promptly. Engage with AdTran support to confirm device configurations and receive updates on official patches or mitigations.

Description

AdTran SRG 834-5 HDC17600021F1 devices (with SmartOS 11.1.1.1 and fixed in Version 12.1.3.1) have SSH enabled by default, accessible both over the LAN and the Internet. During a window of time when the device is being set up, it uses a default username and password combination of admin/admin with root-level privileges. An attacker can exploit this window to gain unauthorized root access by either modifying the existing admin account or creating a new account with equivalent privileges. This vulnerability allows attackers to execute arbitrary commands. NOTE: The vendor has disputed this, finding the report not applicable. According to AdTran, SSH has never been accessible (from WAN) on SmartOS official builds. Furthermore, the vendor adds that test build 11.1.0.101-202106231430 was never released to end users.
