Decide on a small number of weaknesses to work with initial, and see the Comprehensive CWE Descriptions To find out more about the weakness, which includes code examples and precise mitigations.
Think all enter is destructive. Use an "acknowledge known fantastic" enter validation system, i.e., make use of a whitelist of suitable inputs that strictly conform to requirements. Reject any enter that doesn't strictly conform to requirements, or completely transform it into something which does. Tend not to rely solely on trying to find malicious or malformed inputs (i.e., will not rely upon a blacklist). On the other hand, blacklists might be beneficial for detecting opportunity attacks or pinpointing which inputs are so malformed that they should be turned down outright. When doing input validation, take into account all likely appropriate Homes, which includes duration, style of input, the entire array of suitable values, missing or further inputs, syntax, regularity throughout similar fields, and conformance to business enterprise principles. For instance of organization rule logic, "boat" these details could possibly be syntactically legitimate since it only is made up of alphanumeric characters, but It's not at all valid in the event you expect colors like "pink" or "blue." When developing OS command strings, use stringent whitelists that limit the character established dependant on the anticipated price of the parameter inside the request. This tends to indirectly Restrict the scope of the attack, but This system is less important than correct output encoding and escaping. Take note that suitable output encoding, escaping, and quoting is the simplest Resolution for preventing OS command injection, Despite the fact that enter validation may possibly supply some defense-in-depth.
