Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data within the java.sql.ResultRow.refreshRow() method when processing column names. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database using the statement terminator, e.g." ;".

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
