Key facts

Description

Snipe-IT before 8.7.0 streams the SQL entry from an uploaded backup archive directly into the MySQL/MariaDB command-line client (`mysql`) without the --binary-mode flag, so the client interprets lines beginning with backslash commands such as `\!` as local shell commands. An authenticated superadministrator who uploads a crafted ZIP backup (POST /admin/backups/upload) and triggers a restore (POST /admin/backups/restore/{filename}) without the optional `clean` sanitizer parameter — which is not applied by default because DB_SANITIZE_BY_DEFAULT is false — can execute arbitrary OS commands as the web application's operating-system user, exposing application secrets (including database credentials and APP_KEY) and allowing modification of application-writable files and data. Version 8.7.0 adds the --binary-mode flag to the client invocation.
