CVE-2024-23817Public exploitNetwork attack vector

Browser script execution via unescaped parameter name

Published Jan 25, 2024 · Updated Jun 17, 2025

HTML injection in Dolibarr ERP & CRM 18.0.4 allows remote attackers to alter home-page content through a crafted login POST. The index.php login path reflects an arbitrary body-parameter name into rendered HTML without neutralizing quotes, angle brackets, or comment delimiters. Exploitation requires user interaction, and injected markup can rewrite the response DOM or execute browser script in the affected session.
