|
This module exploits a code execution flaw in HP AutoPass License Server. It abuses two
|
|
weaknesses in order to get its objective. First, the AutoPass application doesn't enforce
|
|
authentication in the CommunicationServlet component. Second, it's possible to abuse a
|
|
directory traversal when uploading files thorough the same component, allowing to upload
|
|
an arbitrary payload embedded in a JSP. The module has been tested successfully on
|
|
HP AutoPass License Server 8.01 as installed with HP Service Virtualization 3.50.
