Common Weakness Enumeration
- CWE-20 - Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
- CWE-88 - Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')The software constructs a string for a command to executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.
