CVE-2023-28503 is a critical authentication bypass vulnerability affecting 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. An unauthenticated attacker can leverage a special username with a deterministic password to bypass authentication and execute OS commands as the root user. With a CVSS score of 9.8, this vulnerability poses a severe risk due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. While not on the KEV catalog, a Metasploit module exists, and there is community discussion, indicating potential for active exploitation.
