What is CVE-2023-53770?

The MiniDVBLinux 5.4 platform contains a vulnerability that allows unauthorized users to access sensitive system configuration files. This issue arises from an exposed backup download endpoint which can be exploited by sending a GET request with the parameter 'action=getconfig'. Initiating this request enables attackers to retrieve a complete archive of system configurations, including sensitive credentials, thereby posing a significant risk to system integrity and data confidentiality.
