Web Ofisi E-Ticaret v3 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the 'a' parameter. Attackers can send GET requests to with malicious 'a' parameter values to extract sensitive database information.
Web Ofisi E-Ticaret v3 is vulnerable to a critical SQL injection flaw, allowing unauthenticated attackers to compromise the database. Successful exploitation grants attackers the ability to extract sensitive data, including user credentials and potentially control the entire e-commerce platform, leading to data breaches and financial loss.
The vulnerability stems from insufficient input validation and sanitization of the 'a' parameter within the Web Ofisi E-Ticaret v3 application. The application directly incorporates user-supplied input from the 'a' parameter into SQL queries without proper escaping or filtering. This allows attackers to inject malicious SQL code, manipulating the database's behavior and enabling unauthorized access to sensitive information. The root cause is a failure to implement parameterized queries or other secure coding practices to prevent SQL injection.
While no specific APTs are directly linked in the provided information, SQL injection vulnerabilities are commonly exploited by a wide range of threat actors, from opportunistic attackers to sophisticated groups. This vulnerability is a prime target for initial access and data exfiltration. CISA KEV status is unknown given the limited information, but the severity suggests it could be a candidate.
Web application firewalls (WAFs) configured to detect SQL injection attempts.
Network Intrusion Detection Systems (NIDS) monitoring for suspicious HTTP GET requests containing SQL keywords (e.g., 'SELECT', 'UPDATE', 'UNION', 'WHERE') in the 'a' parameter.
Database activity monitoring (DAM) to identify unusual database queries or access patterns.
Reviewing web server logs for suspicious activity, including unusual HTTP requests and error messages.
Analyzing application logs for SQL errors or unexpected behavior related to the 'a' parameter.
Implement parameterized queries or prepared statements to prevent SQL injection. This separates the SQL code from the user-supplied input.
Thoroughly validate and sanitize all user-supplied input, including the 'a' parameter, before incorporating it into SQL queries. Use allowlists instead of denylists.
Apply the latest security patches provided by the vendor.
Implement a Web Application Firewall (WAF) to filter malicious requests.
Regularly audit the application's code for SQL injection vulnerabilities.
Enforce the principle of least privilege for database users. Limit the permissions of the database user account used by the application.
Consider using a web application security scanner to identify and remediate vulnerabilities.
