Internet Security Systems Security Brief April 11, 2006

Microsoft MDAC Remote Code Execution

Summary:
Microsoft has issued an advisory for a vulnerability in Microsoft Data Access Components. Specifically, the RDS.Dataspace ActiveX control provided with MDAC allows attackers to create malicious web pages and create objects with the security context of the logged in user rather than the Internet Explorer DOM.

Business Impact:

Compromise of the operating system can lead to exposure of confidential information, loss of productivity, and further network compromise. Successful exploitation of this vulnerability could be used to gain unauthorized access to one.s networks and machines.

Description:

It is possible to instantiate the RDS.Dataspace ActiveX control and not have it associated with the Internet Explorer DOM. In doing so, it assumes the security context of the currently logged on user and not the DOM. Under this security context, functionality that is typically limited within the DOM is now fully operational. Attackers may leverage this increased privileged security context to execute commands on the target system.

Exploitation of this vulnerability requires the Internet Explorer user to browse to a malicious page. Attackers may attempt to lure users via phishing emails.
