Product Description:

Here we introduce the A-AST Bulk DNS TTL changer v1.0 for cPanel/WHM. With this interface, you get to lower TTL values for multiple domains all at once, and make sure that the DNS information that you change will take effect in a shorter interval of time. What’s more? Once your migration is complete, you can use this same tool to raise the DNS TTL values of multiple domains and thus make life a little easier on name servers.

Vulnerability Description:

Due to insecure file permissions when the plugin is installed, it is possible under certain circumstances for a user to modify the files which could lead to a root compromise.
