Attack Chain

1. An unauthenticated attacker identifies a WebOfisi E-Ticaret 4.0 installation.
2. The attacker crafts a malicious URL targeting the vulnerable endpoint with a crafted SQL payload in the urun GET parameter.
3. The web server processes the request without proper sanitization of the 'urun' parameter.
4. The application constructs a SQL query using the attacker-supplied payload.
5. The database executes the malicious SQL query.
6. The attacker leverages boolean-based blind, error-based, or time-based blind techniques to extract sensitive data from the database.
7. The attacker potentially executes stacked queries to modify or delete data within the database.
8. The attacker gains unauthorized access to sensitive information, modifies website content, or disrupts website functionality.

Impact

Successful exploitation of this SQL injection vulnerability can have severe consequences. Attackers can gain unauthorized access to sensitive customer data, including personal information, financial details, and order history. This can lead to identity theft, financial fraud, and reputational damage for the affected organization. Attackers could also modify product pricing, manipulate inventory levels, or even inject malicious code into the website, leading to further compromise and potential harm to users.

Recommendation

• Apply available patches or upgrade to a secure version of WebOfisi E-Ticaret to address CVE-2018-25210.
• Deploy the Sigma rule provided below to detect potential exploitation attempts targeting the 'urun' parameter in web server logs.
• Implement input validation and sanitization measures to prevent SQL injection vulnerabilities.
• Regularly monitor web server logs for suspicious activity related to SQL injection attempts, focusing on the 'urun' parameter.
• Block access to the malicious URLs specified in the IOCs at your network perimeter.
