|-----------------------------|-----------|--------------------------------------------------------------------|
| Insecure configuration for ASP.NET requestValidationMode (`cs/insecure-request-validation-mode`) | security, external/cwe/cwe-016 | Finds where this attribute has been set to a value less than 4.5, which turns off some validation features and makes the application less secure. |
| Page request validation is disabled (`cs/web/request-validation-disabled`) | security, frameworks/asp.net, external/cwe/cwe-016 | Finds where ASP.NET page request validation has been disabled, which could makes the application less secure. |
