The Website https://torproject.org have a Vulnerability of Directory Listing Which may Loss Some Certain DATA and the Data may Loss to the Attacker. Directory Listing is not Much Vulnerable But Information may Be loss and if the Attacker Try to Tunnel Some Directory so that Information May Leak to which is Critical.
