Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if SAP CrystalReports or BusinessObjects is installedCheck installed programs or running services for SAP CrystalReports WebForm Viewer, SAP BusinessObjects BI Platform, or Crystal Reports for Visual Studio 2010Affected if The software is present on the system
-
Determine the installed versionUse the system installer, program properties, or version information from the SAP/BusinessObjects installation directory to confirm version 4.1, 4.2, or the 2010 version of Crystal Reports for Visual StudioAffected if The installed version matches 4.1, 4.2, or 2010
-
Check if WebForm Viewer component is enabledInspect the SAP BusinessObjects or Crystal Reports configuration files (such as web.xml or viewer configuration) to verify whether the WebForm Viewer is deployed and accessibleAffected if The WebForm Viewer component is deployed and enabled in the configuration
-
Verify network accessibility of the viewerReview firewall rules, IIS/Server configuration, or network ACLs to determine if the WebForm Viewer endpoint (typically under /CrystalReports/viewr) is exposed to network usersAffected if The WebForm Viewer is reachable over the network without additional authentication beyond basic authorization
A user is affected if they have SAP BusinessObjects BI Platform versions 4.1 or 4.2, or Crystal Reports for Visual Studio 2010, with the WebForm Viewer component enabled and accessible.
