This module exploits a code execution flaw in Cisco Data Center Network Manager. The
vulnerability exists in processImageSave.jsp, which can be abused through a directory

traversal and a null byte injection to upload arbitrary files. The autodeploy JBoss
application server feature is used to achieve remote code execution. This module has been
tested successfully on Cisco Prime Data Center Network Manager 6.1(2) on Windows 2008 R2
(64 bits).
