CVE-2022-3193Network attack vector

Reflected XSS via unsanitized error_description parameter

Published Sep 28, 2022 · Updated May 20, 2025

Reflected XSS in oVirt Engine 4.3 allows remote attackers to execute script in a user's browser through error_description. The Windows Service Accounts home page inserts the error_description parameter into generated HTML without neutralizing executable markup. An unauthenticated remote attacker must persuade a user to follow a crafted request; execution is limited to that user's browser context.
