CVE-2023-34447Network attack vector

Reflected XSS via unescaped global search query

Published Oct 25, 2023 · Updated Sep 11, 2024

Cross-site scripting in pages/UI.php in Combodo iTop before 3.0.4 allows remote attackers to execute script via a crafted search URL. DisplayNavigatorGroupTab passes the raw full-text query into search history and the ibo-global-search.sQuery block parameter without HTML escaping. Exploitation requires a victim to open the crafted URL, causing attacker-controlled JavaScript to run in the victim's iTop browser context.
