'Name' => 'ManageEngine Multiple Products Authenticated File Upload',
'Description' => %q{
This module exploits a directory traversal vulnerability in ManageEngine ServiceDesk,
AssetExplorer, SupportCenter and IT360 when uploading attachment files. The JSP that accepts
the upload does not handle correctly '../' sequences, which can be abused to write
in the file system. Authentication is needed to exploit this vulnerability, but this module
will attempt to login using the default credentials for the administrator and guest
accounts. Alternatively you can provide a pre-authenticated cookie or a username / password
combo. For IT360 targets enter the RPORT of the ServiceDesk instance (usually 8400). All
versions of ServiceDesk prior v9 build 9031 (including MSP but excluding v4), AssetExplorer,
SupportCenter and IT360 (including MSP) are vulnerable. At the time of release of this
module, only ServiceDesk v9 has been fixed in build 9031 and above. This module has been
been tested successfully in Windows and Linux on several versions.
