Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly counters improper neutralization of special elements in query input by enforcing validation before processing.
Requires timely patching of the identified flaw in Db2 query logic that enables authenticated DoS.
Limits privileges of authenticated users so that successful exploitation of query logic yields reduced DoS impact.

Security testing in development can detect missing quantity validation but does not itself implement the control.
Secure development lifecycle mandates input validation for quantity fields, directly preventing CWE-1284.
Application security requirements explicitly call for validation of size/length inputs, mitigating CWE-1284.
Secure architecture principles encourage robust input handling but do not specifically address quantity validation.
Secure coding standards require explicit checks on numeric quantity inputs, fully addressing CWE-1284.
