CVE-2024-52000Network attack vector

Script execution via unescaped language-selection errors

Published Nov 8, 2024 · Updated Nov 12, 2024

Reflected XSS in preferred-language handling in Combodo iTop before 3.2.0 allows remote authenticated users to execute JavaScript. Preferred-language request payloads are incorporated into rendered error messages without systematic output escaping, reflecting attacker-controlled markup into the page. Low-privileged access is required, and successful exploitation runs script in the browser context that processes the crafted response.
