Netartmedia Vlog System SQL Injection Vulnerability

The Netartmedia Vlog System is susceptible to SQL injection (CVE-2019-25641). An unauthenticated attacker can exploit this vulnerability by injecting malicious SQL code through the email parameter in the forgotten_password module. The attacker sends crafted POST requests to index.php to manipulate database queries and extract sensitive information. This vulnerability exists due to improper neutralization of special elements used in an SQL command. This vulnerability was reported in March 2026. Successful exploitation allows attackers to potentially access sensitive data, modify database contents, or even gain unauthorized access to the system.

Attack Chain

1. The attacker identifies a Netartmedia Vlog System instance.
2. The attacker crafts a malicious POST request targeting the index.php endpoint.
3. The POST request includes the forgotten_password module.
4. The attacker injects SQL code into the email parameter within the POST data.
5. The vulnerable application processes the crafted POST request without proper sanitization.
6. The injected SQL code is executed against the database.
7. Sensitive data, such as user credentials or configuration details, is extracted.
8. The attacker uses the extracted information for further malicious activities.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2019-25641) can lead to unauthorized access to sensitive data within the Netartmedia Vlog System database. Attackers can potentially steal user credentials, modify system settings, or even gain complete control over the application. The number of affected installations is currently unknown, but any system running a vulnerable version of Netartmedia Vlog System is at risk.

Recommendation

• Inspect web server logs for POST requests to index.php with the forgotten_password module and suspicious characters in the email parameter to detect potential exploitation attempts (webserver logs).
• Apply appropriate input validation and sanitization techniques to the email parameter in the forgotten_password module of the Netartmedia Vlog System to prevent SQL injection attacks.
• Deploy the Sigma rule provided below to detect attempts to exploit this vulnerability.
