CWE-204Observable Response Discrepancy

Abstraction: Base · CVEs in our corpus: 179

The product provides different responses to incoming requests in a way that reveals internal state information to an unauthorized actor outside of the intended control sphere.

Cumulative inbound coverage

How completely the frameworks we cross-walk collectively cover this — the verdict is the strongest single mapping (overlapping partials are not summed); breadth shows the corroboration behind it.

Collective: partial · 5 mapping(s) from 2 framework(s): CAPEC 4 (partial) · ATT&CK 1 (partial)

NIST 800-53 r5 controls that address this weakness (2)AI-assisted

Control Title Family Why it addresses this CWE
SC-30Concealment and MisdirectionSCFake or randomized responses remove distinguishable success/failure signals attackers rely on.
SI-11Error HandlingSIEliminates distinguishable response discrepancies in error conditions that could be exploited for reconnaissance.

MITRE ATT&CK techniques this weakness enables

Our own two-way CWE↔ATT&CK cross-walk — a direct mapping with no public source (the CWE→CAPEC→ATT&CK chain leaves most top weaknesses, incl. XSS and SQLi, mapped to nothing).

Direction: other covers this; this covers other (F/M/P = full / mostly / partial). gov = governs / implements (a mandate, not coverage).
