CVE-2020-29493Network attack vector

Unauthenticated data access via Fitness Analyzer SQL injection

Published Jan 14, 2021 · Updated Sep 16, 2024

SQL injection in Dell Avamar Server 19.1 through 19.3 allows remote attackers to read, write, or delete backup data without authentication. Dell identifies Fitness Analyzer as the affected component but has not published the vulnerable endpoint, parameter, or database-query construction. Network access to the component is sufficient; successful exploitation executes SQL against the backend application database.
