Fixes

Solution

The recommended resolution is to upgrade to a remediated VCO software version at your earliest convenience. These vulnerabilities have been fixed in the following releases: - VCO 5.2.3.16 and later in the 5.2.3 train - VCO 6.4.2.8 and later in the 6.4.2 train Releases in other release trains that fix this will be added over time. For VCOs not on a supported release train, customers can contact TAC to discuss possible upgrade options.


Workaround

Until 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. - Consider blocking outbound ports not needed for normal activities. - Monitor for backdoor daemons and webshells. - Review recent administrator activity for unexpected changes.
