CVE-2020-5276Network attack vector

Authenticated script execution via uncast cartBox identifier

Published Apr 20, 2020 · Updated Aug 4, 2024

Reflected XSS in PrestaShop 1.7.1.0 through 1.7.6.4 allows remote authenticated users to execute script via the AdminCarts cartBox parameter. AdminController::processBulkDelete passes each uncast cartBox identifier into an error translation, allowing supplied markup to be rendered when deletion fails. Exploitation requires back-office access and a victim to interact with the crafted request; resulting script runs in that victim's browser context.
