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. Confirm Oracle Communications Billing and Revenue Management is installed
    Locate the BRM installation directory and identify the installed product binaries. Common locations include $ORACLE_HOME/brm or /opt/oracle/brm. Check for the presence of Connection Manager executables (cm) in the bin directory.
    Affected if The product is present on the system and includes the Connection Manager component.
  2. Identify the installed BRM version
    Run the version check command for your BRM installation. Common methods include: checking the installer logs, running 'cm -version' if available, or inspecting version files in the installation directory under config or version subdirectories.
    Affected if The installed version is exactly 12.0.0.3.0 or 12.0.0.4.0.
  3. Verify Connection Manager HTTP accessibility
    Check the Connection Manager configuration files (typically cm.cfg or cm.xml in the config directory) for HTTP listener configuration. Confirm whether the CM HTTP port is enabled and bound to a network interface.
    Affected if The Connection Manager is configured to listen on an HTTP port and is accessible over the network.
  4. Assess network exposure of the Connection Manager
    Review firewall rules, network configuration, or reverse proxy settings to determine if the CM HTTP port is exposed to untrusted networks. Use 'netstat -an | grep <cm_port>' or 'ss -tlnp | grep <cm_port>' to identify listening ports.
    Affected if The CM HTTP port is listening on a non-localhost address or is accessible from outside the local network.

A system is affected if it runs Oracle Communications Billing and Revenue Management version 12.0.0.3.0 or 12.0.0.4.0 with the Connection Manager HTTP interface enabled and accessible over the network.
