McAfee Security Center IsOldAppInstalled ActiveX Buffer Overflow

iDefense Security Advisory 05.08.07
May 08, 2007


McAfee Security Center is a centralized configuration GUI utilized to
control and monitor McAfee Security products such as their AntiVirus,
Firewall and AntiSpam products. More information can be found on the
vendor's site at the following URL.


Remote exploitation of a buffer overflow in an ActiveX control
distributed with McAfee Security Center could allow for the execution
of arbitrary code.

When McAfee Security products are installed, they register the following
ActiveX control on the system:

  ProgId: McSubMgr.McSubMgr
  ClassId: 9BE8D7B2-329C-442A-A4AC-ABA9D7572602
  File: MCSUBMGR.DLL, (McAfee Subscription manager module

This control is registered as safe for scripting and contains a buffer
overflow in its IsOldAppInstalled() method.


Exploitation of this vulnerability is trivial and allows for the
execution of arbitrary code as the currently logged in user.

In order to be successful, attackers would need to convince a victim to
go to a malicious web site. Although this attack requires some social
engineering, the level required is considered minimal.

Publicly available COM object fuzzing tools such as COMRaider can find
this vulnerability using default settings.

Note that this vulnerability is similar to "McAfee Subscription Manager
Stack Buffer Overflow" that was published by eEye Digital Security. At
the time of eEye's publishing, iDefense was aware of two additional
vulnerabilities within this control. One, located in the
GetUserRegisteredForBackend method, appears to have been fixed along
with the issue eEye reported. The other is detailed in this advisory.


iDefense confirmed the existence of this vulnerability using McAfee
Virus Scan 10.0.27 running on Windows XP SP2. However, many additional
McAfee products are reported to install this component.

The vulnerable component includes the versions of the McAfee
Subscription manager module listed below.

  Version 6.x prior to
  Version 7.x prior to 7.2.147


The following workarounds are available for this vulnerability:

  Disable Active Scripting
  Unregister the vulnerable control
  Set the killbit for the vulnerable control

While these workarounds may prevent exploitation they may also adversely
affect the operation of the McAfee product and should only be considered
as short-term workarounds.


"Security Center 7.2.147 and 6.0.25 address the risk associated with
this security flaw. These updates were made available for download on
March 22, 2007. Most consumers will receive the updates automatically.

Consumers who have their McAfee products configured to update
automatically should have already received the appropriate update and
therefore will not need to take further action.

Consumers who have configured their McAfee products to update manually
must run an update."

For information regarding the manual update process, refer to McAfee's
Security Bulletin at the following URL.
