Rule Definition
The software accesses to a library using externally-influenced input from an upstream component. This could allow attackers to execute unexpected, dangerous commands directly on the operating system. This weakness can lead to a vulnerability in environments in which the attacker does not have direct access to the operating system, such as in web applications.

Remediation
Assume all input is malicious. Avoid using inputs. If it is not possible, use an "accept known good" input validation strategy, i.e., use stringent white-lists that limit the character set based on the expected value of the parameter in the request. This will indirectly limit the scope of an attack.

Violation Code Sample
