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-2013-0593 DESCRIPTION: It is possible for an attacker to compromise the olch2x32 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 the TippingPoint Zero Day Initiative (ZDI) and discovered by a third-party researcher, Alexander Gavrun aka rgod, 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/83382 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 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: {92D71E93-25A8-11CF-A640-9986B64D9618} 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.
