Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation of all inputs to the Zoom client, blocking the malicious payloads that enable the XSS/CSRF vector described in CVE-2025-49462.

SC-23 Session Authenticity good match
prevent

Enforces session authenticity mechanisms (e.g., anti-CSRF tokens or equivalent) that would stop an authenticated user from being tricked into actions leading to information disclosure.

SI-15 Information Output Filtering partial match
prevent

Requires filtering/sanitization of all output rendered by the Zoom client, mitigating reflected or stored XSS that could leak information.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require anti-CSRF controls such as tokens or SameSite attributes.

A.8.23 Web filtering partial match
mitigates

By denying access to phishing or malicious sites, the control lowers the likelihood that a user will be tricked into submitting a forged request that performs an unintended action on another site.

A.5.7 Threat intelligence none match
none

Contextual intelligence about emerging CSRF toolkits can be translated into updated anti-CSRF token or same-site policy configurations across applications.
