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 Oracle Communications Billing and Revenue Management installationLocate the Oracle Communications BRM installation directory and confirm the product is present. Common locations include $ORACLE_HOME or /opt/oracle/brm. Look for billing and revenue management binaries or configuration files.Affected if The product is installed in the environment
-
Determine the installed BRM versionCheck the installed version of Oracle Communications Billing and Revenue Management. This can typically be found in version files, about screens, or by querying the system inventory. Compare your installed version against the affected versions: 12.0.0.4 and 12.0.0.5.Affected if The installed version is exactly 12.0.0.4 or 12.0.0.5
-
Verify Connection Manager component is runningIdentify if the Connection Manager (CM) component is enabled and running. The Connection Manager typically listens on a configurable TCP port. Check for processes related to CM or port listeners associated with BRM.Affected if The Connection Manager is running and listening on a TCP port
-
Check network exposure of the Connection ManagerDetermine if the Connection Manager port is exposed to the network. Identify the port number configured for Connection Manager and verify its listening address. Check firewall rules and network ACLs controlling access to this port.Affected if The Connection Manager port is accessible from untrusted network segments or the internet
A user is affected if they have Oracle Communications Billing and Revenue Management version 12.0.0.4 or 12.0.0.5 with the Connection Manager component exposed to network access.
