Unauthenticated credential disclosure via backup archive download

Published Dec 9, 2025 · Updated Jul 28, 2026

Information disclosure in MiniDVBLinux Distribution 5.4 and earlier allows remote attackers to download sensitive configuration files. The 51_download_backup.sh script accepts action=getconfig without authentication, exports the complete configuration, and returns the archive over HTTP. Network access to the web interface is sufficient to obtain stored password data and other system configuration.
