Frequently Asked Questions (FAQs)

How do I know if my product is vulnerable or not?
If you are using ATD 4.x or IS 5.2.0 and earlier, your device is vulnerable to this CVE.

What is CVSS?
Common Vulnerability Scoring System (CVSS) 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.
 
When calculating CVSS scores, we have 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 don’t factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored.
