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 OBR is installedCheck for Micro Focus Operation Bridge Reporter installation on the system. Look for OBR installation directories (commonly under C:\Program Files\Micro Focus\ or /opt/microfocus/ on Unix) or check for OBR-related processes or services running on the host.Affected if Micro Focus Operation Bridge Reporter is present on the system
-
Determine OBR versionLocate and read the OBR version information. Typically found in the product's About section, version file, or registry entries on Windows systems. Common paths include the OBR installation directory or the Windows registry under HKLM\SOFTWARE\Micro Focus\.Affected if The installed version cannot be determined or is 10.40 or earlier
-
Compare version to affected rangeCompare the installed OBR version against the affected range: version 10.40 and earlier. If the version is 10.40 or any version lower than 10.40, the system is within the affected range.Affected if Installed version is 10.40 or lower (for example, 10.30, 10.20, 10.10, etc.)
The environment is affected if Micro Focus Operation Bridge Reporter is installed and the installed version is 10.40 or any earlier version.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a version newer than 10.40 when available from Micro Focus, or apply vendor-supplied patches; prior to patching, restrict local access to trusted personnel only.
