[Full-disclosure] IRM Security Advisory : RedDot CMS SQL injection vulnerability



RedDot CMS SQL injection vulnerability (CVE Number: CVE-2008-1613)



http://www.irmplc.com/index.php/167-Advisory-026





Vulnerability Type/Importance: SQL injection/Critical



Problem Discovered: 12 February 2008

Vendor Contacted: 19 February 2008

Advisory Published: 21 April 2008





Abstract:

The RedDot CMS Product (http://www.reddot.com) is vulnerable to a
pre-authentication SQL injection vulnerability which, when exploited,
allows enumeration of all SQL database content.



Description:

The 'LngId' Parameter passed to IoRD.asp is responsible for assigning
the language context for the CMS application. The vulnerability exists
as a result of inadequate validation of user-supplied input within this
parameter.





Technical Details:

Normal input for the 'LngId' parameter contains a code such as ENG, DEU,
JP, denoting the language type. This parameter is not properly validated
and the injection of SQL statements within it allows attackers
unrestricted access to enumerate information from the database. For
example:



https://vulnerablehost.com:443/cms/ioRD.asp?Action=ShowMessage&LngId=ENG
.DGC0 FROM IO_DGC_ENG UNION SELECT min(name) FROM SYSOBJECTS where
xtype=char(85) and name> '' ORDER BY 1;-- &DisableAutoLogin=1



Proof of Concept:

A Proof of Concept (RDdbenum.py) has been developed to automate
enumeration of entire database content available from
http://www.irmplc.com/Tools/RDdbenum.py





Workaround / Solutions:

There are no known workarounds for this vulnerability

The Vendor has released a patch for this vulnerability, Release
7.5.1.86, available from normal Red Dot customer support contacts.





Tested / Affected Versions:

IRM confirmed the presence of this vulnerability in RedDot CMS version
7.5 Build 7.5.0.48, tested with Microsoft SQL Server 2005 database.

It is believed that this issue exists in RedDot CMS versions 6.5 and
7.0; however this has not been fully verified.
