Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Arbitrary code execution vulnerability on Micro Focus Operation Bridge Reporter, affecting version 10.40 and earlier. The vulnerability could allow remote attackers to execute arbitrary code on affected installations of OBR.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Arbitrary code execution vulnerability in Micro Focus Operation Bridge Reporter (OBR) version 10.40 and earlier allows remote attackers to execute arbitrary code on affected installations. The specific attack vector and vulnerable component are not detailed in the available description.

MitigationUpgrade Micro Focus Operation Bridge Reporter to a version beyond 10.40 that includes the security patch. If immediate patching is not possible, restrict network access to OBR management interfaces and monitor for suspicious activity.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify OBR installation exists
    Check for Micro Focus Operation Bridge Reporter installation directory (commonly at C:\Program Files\Micro Focus\Operation Bridge Reporter or /opt/microfocus/obr) or look for the 'OBR' service running on the system
    Affected if OBR software is found installed on the system
  2. Determine installed OBR version
    Locate the OBR version information - typically in the product's about dialog, in installation logs, or by checking version files in the installation directory. Compare the installed version against the affected range (10.40 and earlier)
    Affected if Installed version is 10.40 or any earlier version number
  3. Identify OBR management interface exposure
    Check which network ports OBR is listening on (common ports include 8080, 8443, or custom ports configured during setup) using netstat or similar network tools. Determine if these ports are bound to external network interfaces rather than localhost only
    Affected if OBR management ports are listening on external/network-facing IP addresses (0.0.0.0) rather than localhost (127.0.0.1)
  4. Check for unauthorized processes or code execution
    Review running processes on the OBR server for unexpected or suspicious executables, especially those spawned by the OBR service account or running from temp directories
    Affected if Unexpected processes are running, particularly those associated with the OBR service account

The environment is affected if Micro Focus Operation Bridge Reporter version 10.40 or earlier is installed AND the OBR management interface is accessible from the network (not restricted to localhost only).

Upgrade available Upgrade to a release after 10.40
Interim mitigation

Upgrade Micro Focus Operation Bridge Reporter to a version beyond 10.40 that includes the security patch. If immediate patching is not possible, restrict network access to OBR management interfaces and monitor for suspicious activity.

Recommended fix Moderate confidence

Micro Focus Operation Bridge Reporter version 10.40 or later (contact Software Support for exact fixed release)

  1. 1. Identify the current installed version of Micro Focus Operation Bridge Reporter
  2. 2. Back up all OBR configuration data and databases before proceeding with any upgrade
  3. 3. Obtain the latest version of Micro Focus Operation Bridge Reporter from Software Support (softwaresupport.softwaregrp.com)
  4. 4. Follow Micro Focus official upgrade documentation to install the fixed release
  5. 5. Verify the upgrade was successful by checking the OBR version and confirming the service is running
  6. 6. Validate that the previously vulnerable endpoint now requires proper authentication
Caveat Review Micro Focus release notes for any deprecated features or configuration changes between your current version and the target version
