CWE-108: Struts: Unvalidated Action Form
Every Action Form must have a corresponding validation form.
Overview
If a Struts Action Form Mapping specifies a form, it must have a validation form defined under the Struts Validator.
Common consequences
What can happen when CWE-108 is exploited.
Other
Affects: Other
If an action form mapping does not have a validation form defined, it may be vulnerable to a number of attacks that rely on unchecked input. Unchecked input is the root cause of some of today's worst and most common software security problems. Cross-site scripting, SQL injection, and process control vulnerabilities all stem from incomplete or absent input validation.
Other
Affects: Confidentiality, Integrity, Availability, Other
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.
