CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-200Exposure of Sensitive Information to an Unauthorized Actor10,204Restricts error message visibility to authorized recipients, directly reducing unauthorized exposure of sensitive information.
CWE-203Observable Discrepancy836Prevents attackers from using observable differences in error responses to infer internal system details or state.
CWE-209Generation of Error Message Containing Sensitive Information642Explicitly requires error messages to avoid including sensitive or exploitable details while still supporting corrective action.
CWE-497Exposure of Sensitive System Information to an Unauthorized Control Sphere314Ensures sensitive system information is not disclosed outside the intended control sphere through error output.
CWE-204Observable Response Discrepancy149Eliminates distinguishable response discrepancies in error conditions that could be exploited for reconnaissance.
