CWE-612: Improper Authorization of Index Containing Sensitive Information

Weakness ID: 612
Abstraction: Base
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
The product creates a search index of private or sensitive documents, but it does not properly limit index access to actors who are authorized to see the original information.
+ Extended Description
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.
+ Relationships

The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.
