Advisory ID: KUSTODIAN-2011-011

Date published: Jan 13, 2011

*Vulnerability Information*

Class: Directory Traversal

Remotely Exploitable: Yes

Locally Exploitable: Yes

*Software Description*

Provides end-to-end FlexPod management and automation across physical,
virtual, compute, storage and network resources.

Create internal private clouds rapidly with internal standards and
procedures to maximize the infrastructure investments.



Provides comprehensive physical and virtual infrastructure management and

*Vulnerability Description*

jQuery File Tree is a configurable, AJAX file browser plugin for the jQuery
javascript library utilised within the Cloupia application framework.

Unauthenticated access to this module allows a remote attacker to browse
the entire file system of the host server, beyond the realm of the web
service itself.

Cloupia are aware of this flaw and are releasing a patch to mitigate
access. End users are urged to update immediately by contacting the vendor.
