Due to the seriousness of these vulnerabilities, customers are highly encouraged to update to the latest build as soon as possible.

Mitigating Factors

Exploiting these type of vulnerabilities generally require that an attacker has access (physical or remote) to a vulnerable machine. In addition to timely application of patches and updated solutions, customers are also advised to review remote access to critical systems and ensure policies and perimeter security is up-to-date.

These vulnerabilities require authentication on the IWSVA web console.
