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.

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. Identify installed OpenScape 4000 product
    Locate and inspect the installed Atos Unify OpenScape 4000 software on the system. Check for either OpenScape 4000 Assistant or OpenScape 4000 Manager installations.
    Affected if Neither product is installed
  2. Verify product version is exactly 10
    Use the product's built-in version check mechanism, about dialog, or system information panel to determine the installed version number.
    Affected if Version is not exactly 10
  3. Confirm AShbr component is enabled
    Inspect the product configuration or component list to determine whether the AShbr component is present and enabled.
    Affected if AShbr component is not present or not enabled
  4. Check network accessibility of management interface
    Review firewall rules and network configuration to determine if the management interface is exposed to network access.
    Affected if Management interface is not network-accessible (only local access)

The environment is affected if OpenScape 4000 Assistant or Manager version 10 is installed with the AShbr component enabled and the management interface is network-accessible.
