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:


    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:


    The cached resource, which is in fact the victim profile page is returned to the attacker (and to anyone else requesting it).
