Security Bulletin: IBM SPSS SamplePower Vsflex8l ActiveX control vulnerability
(CVE-2012-5945)
Flash (Alert)
Document information
SPSS SamplePower
Software version:
3.0
Operating system(s):
Windows
Reference #:
1635515
Modified date:
2013-04-26
Abstract
There is a security vulnerability with the Vsflex8l ActiveX control shipped by
IBM SPSS SamplePower Version 3. The vulnerability allows remote attackers to
execute arbitrary code on installations of SamplePower when the control is
invoked as ActiveX by Microsoft Internet Explorer.
Content
VULNERABILITY DETAILS:
CVE IDs: CVE-2012-5945
DESCRIPTION: It is possible for an attacker to compromise the Vsflex8l ActiveX
control used within IBM SPSS SamplePower to remotely execute arbitrary code by
instantiating this control from Microsoft Internet Explorer. For a remote
attacker to exploit these vulnerabilities in SamplePower releases, the
following must be accomplished:
The user must have IBM SPSS SamplePower installed on the machine.
Attacker needs to create malicious code that would exploit the ActiveX
control. Buffer overflow occurs when a special malformed string is assigned
to the 'ComboList'(or 'ColComboList') property. The code starting at
10033FD6 looks for a '#' to terminate the string. It then copies the string
into a global buffer in the data section with a static size of 0x64.
It is safe for scripting.
As of April 24, 2013, IBM has not received any reports of customer issues
related to these security vulnerabilities.
These vulnerabilities were reported to IBM by HP's Zero Day Initiative (ZDI)
and discovered by a third-party researcher, Alexander Gavrun, working with ZDI.
CVSS:
Using the Common Vulnerability Scoring System (CVSS) v2, the security ratings
for these issues are:
CVSS Base Score: 9.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/80561 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:C/I:C/A:C)
AFFECTED PLATFORMS:
IBM SPSS SamplePower for Windows V3.0
REMEDIATION:
The recommended solution is to download and install the IBM SamplePower 3.0 FP1.

3.0-IM-S3SAMPC-WIN32-FP001 3.0.0.1 N/A Download 3.0-IM-S3SAMPC-WIN32-FP001
Fix Pack:
In order to remove the old version of the Control, the user should un-install
the current release, download the available Sample Power 3.0.1 Fix Pack 1,
install and re-license with your current Authorization Code.
Download the Fix Pack from IBM Fix Central (3.0-IM-S3SAMPC-WIN32-FP001).
Install the IBM SamplePower 3.0. FP1 on top of your existing installation.
Reboot if necessary.
Mitigation(s):
None known apply the workaround.

Security Bulletin: IBM SPSS SamplePower c1sizer ActiveX control vulnerability
(CVE-2012-5946)
Flash (Alert)
Document information
SPSS SamplePower
Software version:
3.0
Operating system(s):
Windows
Reference #:
1635476
Modified date:
2013-04-26
Abstract
There is a security vulnerability with the c1sizer ActiveX control shipped by
IBM SPSS SamplePower Version 3. The vulnerability allow remote attackers to
execute arbitrary code on installations of SamplePower when the control is
invoked as ActiveX by Microsoft Internet Explorer.
Content
VULNERABILITY DETAILS:
CVE IDs: CVE-2012-5946
DESCRIPTION: It is possible for an attacker to compromise the c1sizer ActiveX
control used within IBM SPSS SamplePower to remotely execute arbitrary code by
instantiating this control from Microsoft Internet Explorer. For a remote
attacker to exploit these vulnerabilities in SamplePower releases, the
following must be accomplished:
The user must have IBM SPSS SamplePower installed on the machine.
Attacker needs to create malicious code that would exploit the ActiveX
control. When handling the TabCaption buffer, C1sizer.ocx does not properly
check the size before running lstrcatA. lpString1 is not large enough to
contain lpString2, and therefore will cause a buffer overflow.
As of April 24 , 2013, IBM has not received any reports of customer issues
related to these security vulnerabilities.
These vulnerabilities were reported to IBM by HP's Zero Day Initiative (ZDI)
and discovered by a third-party researcher, Alexander Gavrun, working with ZDI.

AFFECTED PLATFORMS:

Workaround:
Disable the use of the vulnerable ActiveX control within Internet Explorer.
Note: This solution contains information about modifying the Microsoft
operating system registry. Before making any modifications with the Microsoft
Registry Editor, it is strongly recommended that you make a backup of the
existing registry. For more information about how to back up the registry
refer to Microsoft Knowledge Base article 256986.
The vulnerable ActiveX control can be disabled in Internet Explorer by
manually setting the kill bit. Complete the following steps to set the kill
bit on the machine where SamplePower is installed.
Start the Microsoft Windows Registry Editor (regedit).
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveXCompatibility
Add a new Key:
{24E04EBF-014D-471F-930E-7654B1193BA9}
Select that Key and create a new DWORD value named:
Compatibility Flags
Set the Compatibility Flags value to:
0x00000400
Exit the Registry Editor.
Restart Internet Explorer.
Mitigation(s):
None known apply the workaround.

Security Bulletin: IBM SPSS SamplePower vsflex7l ActiveX control vulnerability
(CVE-2012-5947)
Flash (Alert)
Document information
SPSS SamplePower
Software version:
3.0
Operating system(s):
Windows
Reference #:
1635511
Modified date:
2013-04-26
Abstract
There is a security vulnerability with the vsflex7l ActiveX control shipped by
IBM SPSS SamplePower Version 3. The vulnerability allows remote attackers to
execute arbitrary code on installations of SamplePower when the control is
invoked as ActiveX by Microsoft Internet Explorer.
Content
VULNERABILITY DETAILS:
CVE IDs: CVE-2012-5947
DESCRIPTION: It is possible for an attacker to compromise the vsflex7l ActiveX
control used within IBM SPSS SamplePower to remotely execute arbitrary code by
instantiating this control from Microsoft Internet Explorer. For a remote
attacker to exploit these vulnerabilities in SamplePower releases, the
following must be accomplished:
The user must have IBM SPSS SamplePower installed on the machine.
Important Note: Continuous use of SamplePower is not required; the
vulnerabilities may be exploited against the ActiveX control regardless of
the use of the product.
Attacker needs to create malicious code that would exploit the ActiveX
control. This code could be part of an attachment by means of e-mail or a
Web page.
User must be persuaded to execute the attachment or follow a Web site link
that contains the malicious code via the Microsoft Internet Explorer Web
browser.
If the malicious website is running within Internet Explorer's Internet
Zone, the user must typically authorize the ActiveX pop-up dialog before
it could be used.
As of April 24, 2013, IBM has not received any reports of customer issues
related to these security vulnerabilities.
These vulnerabilities were reported to IBM by HP's Zero Day Initiative (ZDI)
and discovered by a third-party researcher, Alexander Gavrun, working with
