Description
The issue is related to a mechanism that uses AppCache to hijack a URL in a domain. This is achieved by serving files from a sub-path on the domain using fallback. The problem stems from weaknesses in the Application Cache mechanism, which can be exploited by a remote attacker to substitute a domain using the FALLBACK section of the manifest files of isolated sources.
