Weaknesses this control addresses (3)AI
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-200 | Exposure of Sensitive Information to an Unauthorized Actor | 10,204 | Obscuring authentication feedback prevents exposure of sensitive information such as valid usernames or failure reasons to unauthorized actors. |
CWE-209 | Generation of Error Message Containing Sensitive Information | 642 | The control directly mitigates generation of error messages containing sensitive authentication details by requiring obscured feedback instead of verbose responses. |
CWE-549 | Missing Password Field Masking | 15 | Obscuring feedback includes masking password input (e.g., asterisks), which addresses the weakness of missing password field masking. |
