Remediation
To remediate this issue, go to the Product Downloads site, and download the latest version. See the Frequently Asked Questions (FAQs) section for the path to upgrade from older versions to this version.
Download and Installation Instructions
For instructions to download product updates and hotfixes, see KB56057 - How to download Enterprise product updates and documentation. Review the Release Notes and Installation Guide for instructions on how to install these updates. All documentation is available at our Product Documentation site.
Migration
See the Migration Guide for instructions to get to a protected version.
IMPORTANT: When upgrading to the appropriate ATD version with the fix, you must use the migration package. Failure to use the correct migration package causes installation failures and requires a reimage of the appliance.
Frequently Asked Questions (FAQs)
How do I know if my product is vulnerable?
For Appliances:
Use the following instructions for Appliance-based products:
ATD 4.10.0 is applicable to all ATD models - both physical and virtual.

NOTES:
What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council's effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website at: https://www.first.org/cvss/.
When calculating CVSS scores, we've adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored.

Where can I find a list of all Security Bulletins?
All Security Bulletins are published on our Knowledge Center. Security Bulletins are retired (removed) once a product is both End of Sale and End of Support (End of Life).
How do I report a product vulnerability to you?
If you have information about a security issue or vulnerability with a product, follow the instructions provided in KB95563 - Report a vulnerability.
How do you respond to this and any other reported security flaws?
Our key priority is the security of our customers. If a vulnerability is found within any of our software or services, we work closely with the relevant security software development team to ensure the rapid and effective development of a fix and communication plan.
We only publish Security Bulletins if they include something actionable such as a workaround, mitigation, version update, or hotfix. Otherwise, we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. For products that are updated automatically, a non-actionable Security Bulletin might be published to acknowledge the discoverer.

NOTES:
- See Supported Upgrade Paths.
- If you are running ATD version 3.8.x or earlier, we strongly recommend a reimage of the ATD appliance directly to version 4.10 to minimize the number of upgrade steps and avoid potential upgrade failures. See the Migration Criteria.
- Installation could take a minimum of 30 minutes and up to two hours. The time depends on the number of virtual machines and the database size in the deployment.
