Select username, description from users where username='"+name+"' In case you didn’t spot it right away, the input we received from the user was included in the query, as illustrated: Be careful with the code, as it contains a rather severe vulnerability. Now you can access the application you deployed from the following address: The code should work just fine after this process. This code simply provides some information about the user, by including the username from the GET method in the query.Īn easy way to test our vulnerable application is to deploy the docker container using these commands: Result = ("select username, description from users where username='"+ name+"'") Therefore, when user input is placed in any part of the query, malicious queries can be executed and vulnerabilities can be exploited by the attacker. Unfortunately, it does not use a mechanism like Prepared Statement. The official Python library was published by Facebook. Osquery Injection is a vulnerability caused by a misuse of the library, just like SQL Injection or Memcache Injection. SELECT DISTINCT processes.name, listening_ports.port, processes.pid FROM listening_ports JOIN processes USING (pid) This would usually involve a system command, but now you can simply use the query below: Get The Process Name, Port, and PID for All Processes You can list most of the information in /etc/passwd using this simple query: Get the process name, port and PID for all processes.Some of the data below could not be retrieved without the tedious parsing of system files or, even worse, without employing dangerous system commands: Here are some examples of what you can do with osquery and why it’s such a useful utility. You can access the list of predefined tables here. SELECT address FROM etc_hosts WHERE hostnames = 'localhost'
