Exposing system data or debugging information helps an
					adversary learn about the system and form an attack plan.An information exposure occurs when system data or debugging information
						leaves the program through an output stream or logging function that makes
						it accessible to unauthorized parties. An attacker can also cause errors to
						occur by submitting unusual requests to the web application. The response to
						these errors can reveal detailed system information, deny service, cause
						security mechanisms to fail, and crash the server. An attacker can use error
						messages that reveal technologies, operating systems, and product versions
						to tune the attack against known vulnerabilities in these technologies. An
						application may use diagnostic methods that provide significant
						implementation details such as stack traces as part of its error handling
						mechanism.
