CVE-2024-56157Network attack vector

Authenticated XSS via crafted CSV import

Published May 14, 2025 · Updated May 14, 2025

Cross-site scripting in Combodo iTop before 3.1.3 and in 3.2.0 allows remote authenticated users to execute scripts via a crafted CSV import. The CSV import workflow processes attacker-supplied field content without neutralizing it before browser rendering; the exact code locus is undisclosed. The importer must be authenticated and interact with the crafted file, and script execution is confined to that authenticated browser context.
