CWE-524: Use of Cache Containing Sensitive Information
The code uses a cache that contains sensitive information, but the cache can be read by an actor outside of the intended control sphere.
How it's found
Use of Cache Containing Sensitive Information is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
Applications may use caches to improve efficiency when communicating with remote entities or performing intensive calculations. A cache maintains a pool of objects, threads, connections, pages, financial data, passwords, or other resources to minimize the time it takes to initialize and access these resources. If the cache is accessible to unauthorized actors, attackers can read the cache and obtain this sensitive information.
Consequences
- Read Application Data
Mitigations
- Architecture and Design: Protect information stored in cache.
- Architecture and Design: Do not store unnecessarily sensitive information in the cache.
- Architecture and Design: Consider using encryption in the cache.
