CVE-2022-3721Public exploitNetwork attack vector

Stored XSS via unvalidated customer fields

Published Nov 4, 2022 · Updated May 2, 2025

Stored cross-site scripting in Froxlor before 0.10.39 allows remote authenticated users to run script in another user's browser. Admins.php and Customers.php accept name, first-name, company, street, and city values without the descriptive-text validation added by the fix, allowing markup to persist. An attacker needs an account path that can add or edit a customer or administrator record, and a victim must view the stored value for browser-side code to execute.
