Browser script execution via reflected viewname input

Published Aug 29, 2024 · Updated Jul 5, 2026

Reflected XSS in Vtiger CRM 7.4.0 allows remote attackers to execute script in a user's browser through a crafted viewname parameter. The index page returns attacker-controlled viewname input without sufficient output encoding, causing executable markup in a crafted URL to be reflected. No CRM account is required, but a user must follow the crafted link and load the index page for the browser-context code to run.
