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 inputs before they are stored and later rendered in web pages, blocking the stored XSS payload insertion.

SI-15 Information Output Filtering good match
prevent

Requires filtering or encoding of information outputs so that stored malicious scripts cannot execute in users' browsers when pages are generated.

SI-3 Malicious Code Protection partial match
preventdetect

Provides malicious-code detection and blocking mechanisms that can identify and stop execution of injected scripts from stored XSS.
