CVE-2023-34854Public exploitNetwork attack vector

Authenticated code execution via bypassable backup filter

Published Sep 14, 2026 · Updated Sep 14, 2026

Remote code execution in HotelDruid before 3.0.6 allows remote authenticated users to run arbitrary server commands through backup restore. The restore logic in includes/funzioni_backup.php uses an overly specific regular expression that leaves crafted PHP assignments in dati_interconnessioni.php. Valid application credentials and backup-restore access are required; executing the restored file runs commands with the web server's privileges.
