In dotCMS 5.x-22.06, TempFileAPI allows a user to create a temporary file based on a passed in URL, while attempting to block any SSRF access to local IP addresses or private subnets. In resolving this URL, the TempFileAPI follows any 302 redirects that the remote URL returns. Because there is no re-validation of the redirect URL, the TempFileAPI can be used to return data from those local/private hosts that should not be accessible remotely.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
