Remote code execution via uploadimage.php
Published Jan 9, 2020 · Updated Aug 5, 2024
Employee Records System 1.0 unrestricted file upload allows remote authenticated users to execute arbitrary PHP code via uploadimage.php. The endpoint relies on client-side extension validation, so altering global.js permits a .php file upload that the server stores and executes. The attacker needs the high privileges reflected in the published scoring, and successful execution can compromise confidentiality, integrity, and availability.
