dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify IBM Tivoli Provisioning Manager Express for Software Distribution is installedCheck your system for the presence of IBM Tivoli Provisioning Manager Express for Software Distribution 4.1.1. Look in Add/Remove Programs or check common installation directories for this specific version.Affected if The software version installed is exactly 4.1.1
-
Confirm the Isig.isigCtl.1 ActiveX control is registeredCheck the Windows registry for the Isig.isigCtl.1 CLSID under HKEY_CLASSES_ROOT. You can search for 'Isig.isigCtl.1' in the registry using regedit or a command-line search tool.Affected if The Isig.isigCtl.1 ActiveX control is present in the Windows registry
-
Check if the ActiveX control is enabled in Internet ExplorerOpen Internet Explorer, go to Tools > Internet Options > Security > Custom Level, and look for the setting related to 'Isig.isigCtl.1' or ActiveX controls for the relevant security zones. Alternatively, check the registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Ext\PreApproved for the control's CLSID.Affected if The ActiveX control is allowed to run in any Internet Explorer security zone (particularly Internet or Intranet zones)
-
Identify any custom Asset Information files being processedReview any Asset Information files loaded by the software, particularly those from external or untrusted sources. Check the software's logs or file access patterns for recent .isig or Asset Information file operations.Affected if The software is loading or processing Asset Information files, especially from untrusted sources
You are affected if IBM Tivoli Provisioning Manager Express for Software Distribution 4.1.1 is installed AND the Isig.isigCtl.1 ActiveX control is registered and enabled in Internet Explorer.
