CVE-2023-3542Network attack vector

Page-content injection via unneutralized contact fields

Published Jul 7, 2023 · Updated Oct 23, 2024

Cross-site scripting in Thinu Tech ThinuCMS 1.5 allows remote authenticated users to alter page content through contact.php. The contact.php handler places attacker-controlled name or body values into generated HTML without adequate neutralization. Exploitation requires low-privilege access and user interaction, and the published assessment limits impact to browser-rendered content integrity.
