Admin account takeover via unsanitized company field

Published Oct 20, 2023 · Updated Sep 12, 2024

Stored XSS in Small CRM 3.0 allows remote authenticated users to take over an administrator account through a submitted quote. The application stores the Request a Quote Company value without neutralizing script content and renders it when an administrator opens the quote's View page. Exploitation requires a registered user to submit the payload and an administrator to view that quote; the injected JavaScript then runs in the administrator's browser session.
