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.

AdTran 834-5 HDC17600021F1 (SmartOS 11.1.1.1) devices enable the SSH service by default and have a hidden, undocumented, hard-coded support account whose password is based on the devices MAC address. All of the devices internet interfaces share a similar MAC address that only varies in their final octet. This allows network-adjacent attackers to derive the support user's SSH password by decrementing the final octet of the connected gateway address or via the BSSID. An attacker can then execute arbitrary OS commands with root-level privileges. NOTE: The vendor states that there is no intended functionality allowing an attacker to execute arbitrary OS Commands with root-level privileges. The vendor also states that this issue was fixed in SmartOS 12.5.5.1.

Adtran 834-5 11.1.0.101-202106231430, and fixed as of SmartOS Version 12.6.3.1, devices allow OS Command Injection via shell metacharacters to the Ping or Traceroute utility.

Multiple stored cross-site scripting (XSS) vulnerabilities on AdTran NetVanta 3120 18.01.01.00.E devices allow remote attackers to inject arbitrary JavaScript, as demonstrated by /mainPassword.html, /processIdentity.html, /public.html, /dhcp.html, /private.html, /hostname.html, /connectivity.html, /NetworkMonitor.html, /trafficMonitoringConfig.html, and /wizardMain.html.

Adtran SR400ac ping Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Adtran SR400ac routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the ping command, which is available over JSON-RPC. A crafted host parameter can trigger execution of a system call composed from a user-supplied string. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-20525.

SmartRG SR506n 2.5.15 and SR510n 2.6.13 routers are vulnerable to Remote Code Execution (RCE) via the ping host feature.

AdTran Personal Phone Manager 10.8.1 software is vulnerable to an issue that allows for exfiltration of data over DNS. This could allow for exposed AdTran Personal Phone Manager web servers to be used as DNS redirectors to tunnel arbitrary data over DNS. NOTE: The affected appliances NetVanta 7060 and NetVanta 7100 are considered End of Life and as such this issue will not be patched

The AdTran Personal Phone Manager software is vulnerable to multiple reflected cross-site scripting (XSS) issues. These issues impact at minimum versions 10.8.1 and below but potentially impact later versions as well since they have not previously been disclosed. Only version 10.8.1 was able to be confirmed during primary research. NOTE: The affected appliances NetVanta 7060 and NetVanta 7100 are considered End of Life and as such this issue will not be patched
