CVE-2024-47139Network attack vector

Administrator-level JavaScript execution via stored XSS

Published Oct 16, 2024 · Updated Oct 16, 2024

Stored XSS in F5 BIG-IQ 8.0 through 8.2.0 allows remote authenticated users with the Administrator role to run JavaScript. An undisclosed Configuration utility page stores attacker-controlled input without neutralizing script-related HTML tags. Administrator privileges are required to plant the payload, and execution occurs when a logged-in user loads the affected page, exposing that user's session context.
