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.

Fix* 				VRMF 		APAR 	How to acquire fix
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.

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 apply the workaround as soon as possible or 
download and install the IBM SamplePower 3.0 FP1.

Fix* 				VRMF 		APAR 	How to acquire fix
3.0-IM-S3SAMPC-WIN32-FP001 	3.0.0.1 	N/A 	Download 3.0-IM-S3SAMPC-WIN32-FP001

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 
ZDI.
