Background]============================================================

* Versions affected: VTLS Virtua InfoStation.cgi - All Versions under 2014.X
- or 2013.2.X Are Affected
* Release date: 22/08/2014
* Impact: Allows unauthorized disclosure of information; Allows
unauthorized modification; Allows disruption of service

VTLS-Virtua is a full-function library management system, providing
management of circulation, cataloging, serials, acquisitions, course
reserves and more. All functions are fully integrated, allowing any staff
user to access any function at any time according to their library-assigned
permissions [1].

=====[2. Detailed
description]================================================

Due to improper sanitization, InfoStation.cgi is prone to a SQL Injection
vulnerability in its "username" and "password" fields, which could lead an
attacker to take over the server database.

The vulnerability described in this document can be exploited by
manipulating the aforementioned parameters as decribed in the following
example:

http://www.example.com/web_reports/cgi-bin/InfoStation.cgi?mod=login&func=process&database=1&lang_code=en&report_group=Adm&filter=aaa&username=[SQLI]&password=[SQLI]

Currently, the username/password fields on the Infostation login page are
vulnerable to attack through modification of the URL via sql injection.
This is where instead of entering staff/staff or root/root, an actual SQL
statement is sent in its place 'select * from' or 'delete * from' to
modify/query/remove data directly from the database.
We need to verify that the username/password is valid before sending them
to the database to verify status and permissions. This can be achieved
using prepared statements [2].

=====[3. Other contexts &
solutions]==========================================

In 2014.1.1 and 2013.2.4, the InfoStation Log In screen has been improved
so that it is not vulnerable to attack via SQL statement injection.

To have the fix applied, your library would need to update your software to
the most recent 2014.x or 2013.2.x version.
