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.
