** DISPUTED ** Open Dental 16.1 and earlier has a hardcoded MySQL root password, which allows remote attackers to obtain administrative access by leveraging access to intranet TCP port 3306. NOTE: the vendor disputes this issue, stating that the "vulnerability note … is factually false … there is indeed a default blank password, but it can be changed … We recommend that users change it, each customer receives direction."
