Kingdom: Environment

This section includes everything that is outside of the source code but is still critical to the security of the product that is being created. Because the issues covered by this kingdom are not directly related to source code, we separated it from the rest of the kingdoms.

Cache Management: Unspecified Criteria

Universal

Abstract

Insecure cache management policies could lead to information exposure.

Explanation

An HTTP response containing a Vary header indicates that server-driven negotiation was done to determine which content should be delivered. A "*" can be used as the field value, which means that it cannot be determined from the HTTP headers what criteria was used to select content. An attacker can use this behavior to gain valuable insight into the application's business logic and use it to orchestrate targeted attacks.
