Moodle <= 1.6dev get record() SQL injection / remote commands execution

Moodle <= 1.6dev is vulnerable to SQL injection and remote command execution. An attacker can exploit this vulnerability by sending malicious input to the vulnerable application. This can allow the attacker to execute arbitrary SQL commands and execute arbitrary commands on the server.

Mitigation:

Input validation should be used to prevent malicious input from entering the application. Additionally, the application should be configured to use the least privilege necessary.
