Description
The application has a form field that is not validated by a corresponding validation form, which can introduce other weaknesses related to insufficient input validation.
Omitting validation for even a single input field may give attackers the leeway they need to compromise the application. 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.
Modes of Introduction:
– Implementation
Related Weaknesses
CWE-1173
CWE-20
Consequences
Integrity: Unexpected State
Integrity: Bypass Protection Mechanism
If unused fields are not validated, shared business logic in an action may allow attackers to bypass the validation checks that are performed for other uses of the form.
Potential Mitigations
Phase: Implementation
Description:
Validate all form fields. If a field is unused, it is still important to constrain it so that it is empty or undefined.
