Official Description

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.

Technical Analysis

CVE-2023-38120 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

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 8.8.
