CVE-2022-47083Public exploitNetwork attack vector

Authenticated code execution via unsafe object deserialization

Published Jan 10, 2023 · Updated Aug 3, 2024

PHP object injection in Spitfire CMS 1.0.475 allows remote authenticated users to execute arbitrary code via crafted web requests. The cms_backup_values input reaches PHP's unserialize() function, which instantiates attacker-supplied objects without validation. A valid application account is required, and successful exploitation runs code with the web application's privileges.
