CVE-2022-39048Network attack vector

Client-side attacks via crafted assessment_redirect URL

Published Apr 10, 2023 · Updated Feb 7, 2025

Cross-site scripting in the assessment_redirect UI page in ServiceNow Now Platform allows remote attackers to run client-side attacks via a crafted URL. The page fails to neutralize attacker-controlled URL input before generating content in the authenticated user's browser. An authenticated user must click the URL; resulting script execution enables phishing, redirection, or theft of CSRF tokens in that user's session.
