Attack Chain

1. An attacker identifies a KLiK SocialMediaWebsite instance running version 1.0.1 or earlier.
2. The attacker crafts a malicious HTTP request targeting the /includes/get_message_ajax.php endpoint.
3. The attacker injects a SQL payload into the c_id parameter of the HTTP request.
4. The web server processes the request and passes the malicious SQL query to the database.
5. The database executes the injected SQL query without proper sanitization, leading to unintended data retrieval or modification.
6. The attacker retrieves sensitive information from the database, such as user credentials or private messages.
7. The attacker may use the stolen credentials to gain unauthorized access to user accounts.

Impact

Successful exploitation of this SQL injection vulnerability can lead to unauthorized access to sensitive data stored in the KLiK SocialMediaWebsite database. This could include user credentials, private messages, and other personal information. An attacker could potentially gain complete control over the application’s data, leading to data breaches, identity theft, and other malicious activities. Given the wide use of social media platforms, a successful attack could affect a large number of users.

Recommendation

• Apply any available patches or updates for KLiK SocialMediaWebsite to address CVE-2026-7002.
• Implement proper input validation and sanitization techniques to prevent SQL injection attacks.
• Deploy the Sigma rule to detect attempts to exploit this SQL injection vulnerability by monitoring web server logs for suspicious requests targeting /includes/get_message_ajax.php with potentially malicious SQL payloads in the c_id parameter.
• Monitor web server logs for HTTP requests to /includes/get_message_ajax.php containing SQL keywords (e.g., SELECT, UNION, UPDATE, INSERT, DELETE) in the c_id parameter.
