Official description

MiniDVBLinux 5.4 contains an unauthenticated configuration download vulnerability that allows remote attackers to access sensitive system configuration files through a direct object reference. Attackers can exploit the backup download endpoint by sending a GET request with 'action=getconfig' to retrieve a complete system configuration archive containing sensitive credentials.

The underlying weakness: Password in Configuration File

The product stores a password in a configuration file that might be accessible to actors who do not know the password.

How developers prevent this class of flaw

  • Avoid storing passwords in easily accessible locations.
  • Consider storing cryptographic hashes of passwords as an alternative to storing in plaintext.
