Enclose the input parameters with a ReplaceURLDomain() function from HttpRequestHandler to avoid open redirect vulnerabilities.
- The input parameter mentioned in the warning has a value that comes from the end-user input and that is susceptible to contain a malicious URL.
Do one of the following:
- Use the ReplaceURLDomain() function from the HTTPRequestHandler extension module to enclose the value of the parameter;
- Replace the 'External Site' element with a well-known page in your application;
- Replace the 'External Site' element with another 'External Site' element that does not receive a URL as an input and that redirects to a static URL instead.
