Update: Vendor acknowledges this issue and has stated that the versions in use are being addressed in a future release.

3. Multiple Web Virtual Directories leak sensitive information about data,  software versions, virtual machines running on the devices and configuration information via unauthenticated access to the installed webserver.

4. Remote Code Execution can be accomplished by executing PHP scripts available to an unauthenticated user accessing the vulnerable webserver.


Update: Working with vendor on this issue.

5. Device/VM restore mount points allow unauthenticated access to them by default, allowing a remote attacker to access sensitive information and data.


Update: Vendor acknowledges this issue and has stated that the end users can (and should) apply an ACL to the folders created inside of the administration console.
