How the Exploit Works
The vulnerabilities are SQL injections, which occur when a malicious user inputs SQL statements in a web application’s user input fields to manipulate the application’s database. In this scenario, the vulnerabilities lie in createStudents.php, specifically in the Id, firstname, and admissionNumber parameters.
By exploiting these SQL injection vulnerabilities, an attacker can execute arbitrary SQL code in the application’s database. This can lead to unauthorized viewing of data, data manipulation, and in worst-case scenarios, complete system compromise.
Conceptual Example Code
A potential exploitation of this vulnerability might look something like this:
POST /createStudents.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
Id=1' OR '1'='1'; DROP TABLE students; -- &firstname=John&admissionNumber=123456In this example, the attacker attempts to delete the ‘students’ table from the database. The ‘OR ‘1’=’1′ ensures the query always returns true, while the ‘;’ allows for a new command to be started, in this case, to drop the ‘students’ table. The ‘–‘ comments out the rest of the query to avoid syntax errors.
An important note: The above is a conceptual example and should not be executed or utilized for malicious purposes. It’s presented to illustrate the potential danger of the vulnerability.
