Description
If a form bean does not extend an ActionForm subclass of the Validator framework, it can expose the application to other weaknesses related to insufficient input validation.
Common Consequences
- Scope:
- Other
- Impact:
- Other
- Notes:
- Bypassing the validation framework for a form exposes the application to numerous types of attacks. Unchecked input is an important component of vulnerabilities like cross-site scripting, process control, and SQL injection.
- Scope:
- Confidentiality, Integrity, Availability, Other
- Impact:
- Other
