Unauthenticated code execution via unrestricted PHP callbacks
Published Jan 16, 2023 · Updated Apr 4, 2025
Remote code execution in ODude Network User Post Gallery - UPG 2.19 and earlier allows remote attackers to run code via a public AJAX action. The upg_datatable nopriv AJAX handler accepts attacker-controlled field entries as callback names and arguments without an allowlist, enabling invocation of PHP functions such as exec. No authentication or user interaction is required, and successful exploitation permits arbitrary shell commands and persistent site compromise through uploaded web shells.
