I found that a website is using a version of telerik web ui that may be vulnerable to cve-2017-9248.
However when i use the python script with command
python script.py -k https://www.website.com/Telerik.Web.UI.DialogHandler.aspx 48 hex 9
The script starts but it's not moving from the first key. It keeps trying to retrieve the first key
`to find key of length  with accuracy threshold  using key charset [01234567890ABCDEF]
Key position 01: (E) [A]`
Does that mean that the website is not vulnerable or the version of Telerik is no more vulnerable?
The version should be:
