High severity, CVSS 10.0. EPSS: 5.1% chance of exploitation in the next 30 days.

Meridian Prolog Manager 2007, and 7.5 and earlier, sends all usernames and passwords to the client in a (1) cleartext or (2) weakly encrypted format to support client-side login authentication, which makes it easier for remote attackers to obtain database access by capturing credentials via a man-in-the-middle attack.

Affected products

• Meridian Software Prolog Manager: version 7.0 only; version 7.5 only; version 2007 only
