DELL EMC Avamar Server, versions 19.1, 19.2, 19.3, contain a SQL Injection Vulnerability in Fitness Analyzer. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to the execution of certain SQL commands on the application's backend database, causing unauthorized read and write access to application data. Exploitation may lead to leakage or deletion of sensitive backup data; hence the severity is Critical. Dell EMC recommends customers to upgrade at the earliest opportunity.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
