Weakness Name

Struts: Form Bean Does Not Extend Validation Class

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

Notes: Although J2EE applications are not generally susceptible to memory corruption attacks, if a J2EE application interfaces with native code that does not perform array bounds checking, an attacker may be able to use an input validation mistake in the J2EE application to launch a buffer overflow attack.
