Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Apache OpenMeetings before 3.3.0 is vulnerable to SQL injection. This allows authenticated users to modify the structure of the existing query and leak the structure of other queries being made by the application in the back-end.
CWE-89 - SQL Injection
Structured Query Language (SQL) injection attacks are one of the most common types of vulnerabilities. They exploit weaknesses in vulnerable applications to gain unauthorized access to backend databases. This often occurs when an attacker enters unexpected SQL syntax in an input field. The resulting SQL statement behaves in the background in an unintended manner, which allows the possibility of unauthorized data retrieval, data modification, execution of database administration operations, and execution of commands on the operating system.
