itsourcecode Content Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the itsourcecode Content Management System version 1.0. The issue resides in the file '/admin/update_main_topic_img.php' when the 'topic_id' parameter is set to 529. This vulnerability allows remote attackers to inject malicious SQL queries through the 'stopic_id' parameter, exploiting inadequate input validation. The injection can be leveraged to manipulate SQL queries, potentially leading to unauthorized database access, data modification, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, which could be used to access, modify, or delete database information. Additionally, such vulnerabilities can sometimes be exploited to execute administrative operations on the database or, in certain configurations, to execute commands on the server operating system.

Reproduction

The vulnerability can be reproduced by sending a request to the '/admin/update_main_topic_img.php' file with a crafted 'topic_id' parameter that includes SQL injection payloads. This can be done using tools like sqlmap, which automate the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Input validation and filtering should be implemented to ensure user input conforms to expected formats. Additionally, database user permissions should be minimized, granting only the necessary access rights.
