Validating form elements

Alternatively, an attacker can provide very large negative values which will cause an integer overflow (CWE-190) and unexpected behavior will follow depending on how the values are treated in the remainder of the program.Example 3The following example shows a PHP application in which the programmer attempts to display a user's birthday and homepage.Subsequent use of n may result in the use of an uninitialized variable (CWE-457).Example 5The following example takes a user-supplied value to allocate an array of objects and then operates on the array.Depending on the context of the code, CRLF Injection (CWE-93), Argument Injection (CWE-88), or Command Injection (CWE-77) may also be possible.

The user has no control over the price variable, however the code does not prevent a negative value from being specified for quantity.This allows the analyst to focus on areas of the software in which input validation does not appear to be present.Except in the cases described in the previous paragraph, automated static analysis might not be able to recognize when proper input validation is being performed, leading to false positives - i.e., warnings that do not have any security consequences or require any code changes.In some cases its usage can obscure the real underlying weakness or otherwise hide chaining and composite relationships.Some people use "input validation" as a general term that covers many different neutralization techniques for ensuring that input is appropriate, such as filtering, canonicalization, and escaping.
