How the Exploit Works
This SQL Injection vulnerability stems from the improper neutralization of special elements used in an SQL command within the Message Filter for Contact Form 7. An attacker can send specially crafted data through the contact form, which the application includes in an SQL query without proper sanitization. This allows the attacker to manipulate the query to extract, alter, or delete data from the database or potentially gain administrative access.
Conceptual Example Code
Consider the following conceptual example of how the vulnerability might be exploited. Let’s assume the attacker sends the following data through the contact form:
POST /contact/form HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
name=John&email=john@example.com&message=hello'; DROP TABLE users; --In this example, the attacker attempts to inject `’hello’; DROP TABLE users; –` as the message, which if processed improperly, could lead to the execution of the SQL command `DROP TABLE users`, leading to the deletion of the ‘users’ table from the database.
