Original NVD Description

Rocket Software UniData versions prior to 8.2.4 build 3003 and UniVerse versions prior to 11.3.5 build 1001 or 12.2.1 build 2002 suffer from an authentication bypass vulnerability, where a special username with a deterministic password can be leveraged to bypass authentication checks and execute OS commands as the root user.
