Microsoft Agent Crafted URL Stack Buffer Overflow

Assurent ID: FSC20070911-11

1. Affected Software

Microsoft Agent, version 2.0.0.3425 (bundled with Windows 2000 Service Pack
4)

Reference: http://www.microsoft.com/msagent/

2. Vulnerability Summary

The Microsoft Agent ActiveX control contains a buffer overflow
vulnerability that allows remote attackers to inject and execute arbitrary
code with the privileges of the currently logged in user.

The affected ActiveX control is registered as below:

File: agentdpv.dll
ProgID: Agent.Control
CLASSID: D45FD31B-5C6E-11D1-9EC1-00C04FD7081F

3. Vulnerability Analysis

The target user is enticed to view a malicious web page. The script in the
web page calls a method of the affected ActiveX control with malicious
arguments. A stack-based buffer will be overrun upon processing the
malicious script.

Assurent has confirmed that code execution is possible. The code in such a
case would execute within the security context of the currently logged in
user.

In an attack case where code injection is not successful, the affected
application will terminate abnormally.

Note that although this vulnerability is exploited through Internet
Explorer, the affected application is the Microsoft Agent application.

4. Vulnerability Detection

Assurent has confirmed the vulnerability in Microsoft Agent shipped with
Windows 2000 SP4. The confirmed vulnerable file version is 2.0.0.3425.
Earlier versions may also be affected.

5. Workaround

Setting the kill bit for the vulnerable ActiveX control's CLSID will
prevent this issue from being exploited via Internet Explorer.

6. Vendor Response

Microsoft has released a bulletin addressing this vulnerability as part of
the September 2007 update cycle.
