Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation and neutralization of untrusted input before it is used in web page generation, addressing the root cause of the reflected XSS flaw.

SI-15 Information Output Filtering good match
prevent

Requires filtering or encoding of information on output to browsers, preventing injected scripts from executing in reflected XSS responses.

SI-3 Malicious Code Protection partial match
preventdetect

Provides mechanisms to detect and block malicious code (scripts) delivered via web requests or responses, mitigating exploitation of the unsanitized input.
