Cross-Site Scripting (XSS) vulnerabilities exist in ServiceNow records allowing an authenticated attacker to inject arbitrary scripts.

A XSS vulnerability was identified in the ServiceNow UI page assessment_redirect. To exploit this vulnerability, an attacker would need to persuade an authenticated user to click a maliciously crafted URL. Successful exploitation potentially could be used to conduct various client-side attacks, including, but not limited to, phishing, redirection, theft of CSRF tokens, and use of an authenticated user's browser or session to attack other systems.

There exists a reflected XSS within the logout functionality of ServiceNow versions lower than Quebec Patch 10 Hotfix 11b, Rome Patch 10 Hotfix 3b, San Diego Patch 9, Tokyo Patch 4, and Utah GA. This enables an unauthenticated remote attacker to execute arbitrary JavaScript code in the browser-based web console.
