However, the parameter 'table' is vulnerable to post-auth SQL Injection. Authenticated users can easily dump all databases, tables and contents including the MySQL database schema. Manually testing the panel I identified an SQL error probing the following URL /AgentTeslaBuilder/server_side/scripts/server_processing.php?table=%27HELL%20OR%201=1 which gave me "An SQL error occurred: SQLSTATE[42S02] Base table or view not found 1146 Table 'agenttesla.'hell or 1=1' doesn't exist" Then switched to use Sqlmap to do the heavy lifting.
