Deeper analysis

CVE-2022-38841 is an OS command injection vulnerability in the Linksys AX3200 router running firmware version 1.1.00. The flaw, classified under CWE-78, resides in the diagnostics traceroute page where authenticated users can supply shell metacharacters that are passed directly to the underlying operating system. It carries a CVSS 3.1 base score of 8.8, reflecting network-accessible exploitation with low attack complexity and no user interaction required.

An authenticated attacker with network access to the device can leverage the injection to execute arbitrary operating-system commands. Successful exploitation grants the attacker full control over confidentiality, integrity, and availability of the router, enabling actions such as configuration changes, traffic interception, or persistence mechanisms.

Public references consist of exploit code and supporting materials hosted on Packet Storm and Google Drive; no vendor advisory or patch information is included in the available data. The EPSS score stands at 0.1663 with no indicated change since disclosure.
