CVE-2021-43978

Database data exposure and modification via embedded credentials

Published Dec 8, 2021 · Updated May 30, 2025

Insufficient credential protection in Allegro Windows 3.3.4152.0 and earlier allows attackers to read and modify data via embedded database credentials. The application's binary files contain reusable software-administrator database credentials rather than keeping them outside distributed executables. Possession of an affected binary exposes credentials that grant direct database access, bounding the impact to database confidentiality and integrity.
