CVE-2023-6609Public exploitNetwork attack vector

Browser script execution via unescaped keywords parameter

Published Dec 8, 2023 · Updated Aug 2, 2024

Reflected XSS in osCommerce 4 allows remote authenticated users to run JavaScript in another user's browser via the keywords parameter. The all-products route places the decoded keywords value into page output without neutralizing HTML event-handler markup. An authenticated attacker must persuade another user to open the crafted request; the injected script alters page behavior in that user's browser context.
