CVE-2022-0848Public exploitNetwork attack vector

Unauthenticated code execution via unsafe file upload

Published Mar 4, 2022 · Updated Aug 2, 2024

OS command injection in Part-DB before 0.5.11 allows remote attackers to execute arbitrary server commands via a crafted label logo upload. The show_part_label.php logo_file handler passes an uploaded filename to uploadFile, whose legacy denylist rejects only names containing .php and accepts executable .phtml files into data/media/labels. No authentication or user interaction is required, and successful exploitation runs attacker-supplied PHP with the web server process's access.
