SourceCodester Online Class Record System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in SourceCodester Online Class Record System version 1.0. The issue arises in the file '/admin/message/search.php', where insufficient input validation of the 'term' parameter allows remote attackers to inject malicious SQL queries. This vulnerability could lead to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized access to the database, modification or deletion of data, and exposure of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a GET request to '/admin/message/search.php' with a crafted 'term' parameter that includes malicious SQL payloads. This can be done using a web browser or a tool like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate this vulnerability.
