CVE-2023-43981Network attack vector

Unauthenticated code execution via unsafe PHP deserialization

Published Oct 5, 2023 · Updated Sep 19, 2024

Deserialization in Presto Changeo Test Site Creator 1.1.1 and earlier allows remote attackers to execute code via crafted HTTP input. delete_excluded_folder.php and verify_excluded_folder.php pass the tsc_excluded_folders request value directly to PHP unserialize() without disabling object instantiation. No authentication or user interaction is required, and successful exploitation grants administrative access and permits theft or removal of associated PrestaShop data.
