CVE-2023-39530Network attack vector

Authenticated file deletion via unchecked attachment path

Published Aug 7, 2023 · Updated Oct 8, 2024

Improper input validation in PrestaShop before 8.1.1 allows remote authenticated users to delete server files via the CustomerMessage API. CustomerMessage::delete appends file_name to the upload directory and passes the unchecked path to unlink, permitting traversal beyond that directory. High-privilege back-office access is required; successful exploitation can remove server files reachable through the crafted path.
