Abstract
Use the Struts Validator to prevent vulnerabilities that result from unchecked input.
Description
Unchecked input is the leading cause of vulnerabilities in J2EE applications. Unchecked input leads to cross-site scripting, process control, and SQL injection vulnerabilities, among others. 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.
To prevent such attacks, use the Struts Validator to check all program input before it is processed by the application.
Example uses of the validator include checking to ensure that:
- Phone number fields contain only valid characters in phone numbers
- Boolean values are only "T" or "F"
- Free-form strings are of a reasonable length and composition
