In more detail

Web sites and other document repositories may apply an indexing routine against a group of private documents to facilitate search. If the index's results are available to parties who do not have access to the documents being indexed, then attackers could obtain portions of the documents by conducting targeted searches and reading the results. The risk is especially dangerous if search results include surrounding text that was not part of the search query. This issue can appear in search engines that are not configured (or implemented) to ignore critical files that should remain hidden; even without permissions to download these files directly, the remote user could read them.

What an attacker can do

  • Read Application Data (Confidentiality)
