Update on CVE-2015-2081 : Multiple Vulnerabilities in Datto Siris and Alto

Interesting post on the DATTO vulnerabilities we had discovered in February (and some additional items that were not covered in our post):
Our investigation turned up a vulnerable webserver as well. As part of that, we investigated some of the pages and services available. We decided to keep these findings private with the vendor and publishing as a CVE at the time and we did so. As another security researcher has posted some of these findings as well and rooted the box publicly, we're releasing this as it's useful for remediation of additional issues that are present on the device.
The below pages and information were available from the webserver embedded, without authentication.

Potentially Dangerous Information Leakage:
 All of these help determine what is running the webserver and versioning behind it.

Session Expired when visited. This suggests the request is processed and the server may be vulnerable to cookie stealing or session hijacking 

Access is Forbidden. Not a internal message or error, suggests the same finding as above. 

Significant amount of PHP scripts for launching just about any function on the device, unauthenticated. Extremely critical to fix. Can be used to establish a reverse shell, a foothold in the server or any number of attacks against the device and data.

Processes, blank page.

Temp directory, reveals sensitive information. For example, the desktop screenshot gives username, system name, OS version, internal directory structure and software information

Internal 500 error. Useful if structure can be determined.

Useful for determining what software and attack surfaces are available. For example, Ajax is vulnerable and it can be determined with this directory that it's installed and available.

Can view/download JavaScript code, extremely useful for any number of attacks.

Reveals a lot of private information about the box. May be by design.

/about (and its subdirectories)
Significant amount of useful information for determining software loads, versioning

Empty. Available to view

internal structure, software loads and setup scripting.

All of the css sheets. Very useful for a number of attacks. 

The vendor was made aware of these issues in February and stated they were working on remediation.
