CWE-202: Exposure of Sensitive Information Through Data Queries
When trying to keep information confidential, an attacker can often infer some of the information by using statistics.
How it's found
Exposure of Sensitive Information Through Data Queries 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.
In situations where data should not be tied to individual users, but a large number of users should be able to make queries that "scrub" the identity of users, it may be possible to get information about a user -- e.g., by specifying search terms that are known to be unique to that user.
Consequences
- Read Files or Directories, Read Application Data: Sensitive information may possibly be leaked through data queries accidentally.
Mitigations
- Architecture and Design: This is a complex topic. See the [REF-1492] for a good discussion of best practices.
