Believe all input is malicious. Use an "acknowledge identified excellent" enter validation strategy, i.e., utilize a whitelist of satisfactory inputs that strictly conform to requirements. Reject any input that doesn't strictly conform to specifications, or completely transform it into something that does. Don't count completely on in search of destructive or malformed inputs (i.e., tend not to rely on a blacklist). However, blacklists could be helpful for detecting prospective attacks or identifying which inputs are so malformed that they must be rejected outright. When accomplishing input validation, contemplate all probably pertinent Houses, which includes length, variety of input, the total variety of suitable values, missing or further inputs, syntax, consistency across related fields, and conformance to business enterprise procedures. As an example of business enterprise rule logic, "boat" could possibly be syntactically legitimate mainly because it only contains alphanumeric characters, but It's not necessarily legitimate in case you predict shades for example "crimson" or "blue." When setting up OS command strings, use stringent whitelists that limit the character established depending on the expected price of the parameter in the request. This tends to indirectly Restrict the scope of the attack, but this technique is less significant than appropriate output encoding and escaping. Notice that appropriate output encoding, escaping, and quoting is the most effective Resolution for avoiding OS command injection, Though input validation may perhaps present some protection-in-depth.
This will likely pressure you to definitely carry out validation actions that remove the taint, Despite the fact that it's essential to watch out to properly validate your inputs so you usually do not accidentally mark risky inputs as untainted (see CWE-183 and CWE-184).

For virtually any stability checks that are performed within the consumer side, ensure that these checks are duplicated over the server side, to be able to stay clear of CWE-602.
