Web Cache Deception

These preconditions can be exploited for the Web Cache Deception attack in the following manner:

  • Step 1: An attacker entices the victim to open a maliciously crafted link: https://www.example.com/my_profile/test.jpg The application ignores the ‘test.jpg’ part of the URL, the victim profile page is loaded. The caching mechanism identifies the resource as an image, caching it.
  • Step 2: The attacker sends a GET request for the cached page: https://www.example.com/my_profile/test.jpg The cached resource, which is in fact the victim profile page is returned to the attacker (and to anyone else requesting it).
