Introduction:

You can easily manage all of your documents with Omnistar Document Management Software. Perform multiple uploads
of large files and deliver them without using attachments. Never worry about which employees have and don t have
accounts with unlimited users. Setup user groups to manage thousands of users and set own permissions.

Abstract:

The Vulnerability Laboratory Research Team discovered multiple critical Web Vulnerabilities in Omnistardrives Omnistar Document Manager v8.0.

Report-Timeline:

2012-10-03: Public or Non-Public Disclosure

Status:

Published

Affected Products:

Omnistar Interactive
Product: Document Manager v8.0

Exploitation-Technique:

Remote

Severity:

Critical

Details:

1.1
Multiple SQL Injection Vulnerabilities are detected in Omnistardrives Omnistar Document Manager v8.0 web application.
The sql injection vulnerability allows an remote attacker to inject own sql commands/statements on the affected application dbms.
The vulnerabilities are detected in the user portal and admin section of the application. The sql vulnerabilities can be exploitation
by remote attackers without privileged application user or admin account. The sql bugs are located index.php file with the bound
vulnerable report_id, delete_id, add_id, return_to, interface, page & sort_order parameter requests. Successful exploitation of the
vulnerabilities results in application dbms compromise & dbms manipulation via sql injection.

Vulnerable Section(s):
[+] /user
[+] /admin

Vulnerable Module(s):
[+] index.php

Vulnerable Parameter(s):
[+] report&id=
[+] sort_order
[+] delete&id=
[+] page=
[+] interface=

1.2
A local file include vulnerability is detected in Omnistardrives Omnistar Document Manager v8.0 web application.
The vulnerability allows a local privileged user account to include and load local system files. The vulnerability
is located in the index module with the bound vulnerable area parameter request. Successful exploitation of the
vulnerability results in a web server compromise via file load or information disclosure via local system file include.

Vulnerable Section(s):
[+] /user
[+] /admin

Vulnerable Module(s):
[+] index.php
[+] class.inc.php

Vulnerable Parameter(s):
[+] area=

1.3
Multiple non persistent cross site scripting vulnerabilities are detected in Omnistardrives Omnistar Document Manager v8.0 web application.
The vulnerabilities allow remote attackers to hijack administrator/moderator/customer sessions via persistent malicious script code inject
on application side. The vulnerabilities are located in the interface exception-handling module of the application with the client side
bound vulnerable interface, act, name & alert_msg parameter requests.

Vulnerable Section(s):
[+] /user
[+] /admin

Vulnerable Module(s):
[+] index.php

Vulnerable Parameter(s):
[+] interface
[+] act
[+] name
[+] alert_msg

Proof of Concept:

1.1
The sql injection vulnerabilities can be exploited by remote attackers without required user inter action and without privileged application
user account. For demonstration or reproduce …

Risk:

1.1
The security risk of the remote sql injection vulnerabilities are estimated as critical.

1.2
The security risk of the local file include vulnerability is etimated as high(-).
