Fixes

Solution

The recommended resolution is to upgrade to a fixed VCO release at your earliest convenience. This vulnerability has been fixed in the following releases:   * VCO 5.2.3.14 and later in the 5.2 train * VCO 6.1.3.4 and later in the 6.1 train * VCO 6.4.2.4 and later in the 6.4 train


Workaround

The recommended resolution is to upgrade to a fixed VCO release as soon as it is available. For VCOs which are not on a supported release train, customers can contact TAC to discuss possible upgrade options for your release. Until the fixed software is deployed, operators should apply defense-in-depth controls appropriate for their environment: * Restrict access to the VCO web interface to trusted administrative networks. * Monitor the VCO for accesses from known malicious source IPs. * Monitor for unexpected outbound network activity from the VCO host. * Review recent administrator activity for unexpected changes.
