PowerShell script to see if a website is affected by the 'React2Shell' vulnerability.
This script uses a specially crafted HTTP POST request and looks for a specific response which indicates whether the vulnerability is present. The script was built based on this research by Searchlight Cyber.
I've provided the script "as is" and assume no liability for any data loss, service disruption or any other detrimental impacts that arise from its usage.
