Web Ofisi Platinum E-Ticaret v5 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the 'q' parameter. Attackers can send POST requests to the ajax/productsFilterSearch endpoint with malicious 'q' values using time-based blind SQL injection techniques to extract sensitive database information.
Web Ofisi Platinum E-Ticaret v5 is vulnerable to a critical SQL injection flaw, allowing unauthenticated attackers to remotely compromise the database. This vulnerability, exploitable via the q parameter in the ajax/productsFilterSearch endpoint, enables attackers to extract sensitive data and potentially achieve full system control.
Step 1: Payload Delivery: The attacker crafts a malicious SQL injection payload designed to exploit the vulnerability in the q parameter of the ajax/productsFilterSearch endpoint. This payload is designed to extract information using time-based techniques.
The vulnerability stems from insufficient input validation and sanitization of the q parameter within the ajax/productsFilterSearch endpoint. The application directly incorporates user-supplied input into SQL queries without proper escaping or filtering. This allows an attacker to inject malicious SQL code, manipulating the query's logic and enabling unauthorized data access. The use of time-based blind SQL injection indicates the application doesn't directly display query results, but the attacker can infer information based on the response time of the server. The root cause is a missing or inadequate implementation of parameterized queries or prepared statements, which would prevent the interpretation of user input as executable SQL code. Specifically, the application likely uses string concatenation to build SQL queries, making it susceptible to injection.
While no specific APT groups are directly linked to this CVE, the nature of SQL injection makes it a common attack vector for various threat actors, including those seeking data theft and initial access. CISA KEV status: Not Listed.
Web application firewall (WAF) logs showing suspicious POST requests to the ajax/productsFilterSearch endpoint with unusual q parameter values (e.g., SQL keywords, time-delay functions).
Network traffic analysis revealing POST requests to the vulnerable endpoint with payloads containing SQL injection attempts (e.g., ' OR '1'='1 or SLEEP(5)).
Database server logs indicating unusual query patterns or unexpected errors related to the ajax/productsFilterSearch endpoint.
Intrusion Detection System (IDS) alerts triggered by SQL injection signatures.
Implement parameterized queries or prepared statements to prevent SQL injection. This ensures that user-supplied input is treated as data, not executable code.
Thoroughly validate and sanitize all user-supplied input, including the q parameter, before incorporating it into SQL queries. Use allowlisting instead of denylisting.
Apply the principle of least privilege to database user accounts. Limit the permissions of the database user account used by the web application to the minimum required for its functionality.
Regularly update the Web Ofisi Platinum E-Ticaret software to the latest version, which may include patches for this vulnerability.
Implement a Web Application Firewall (WAF) to filter malicious requests.
Conduct regular penetration testing and vulnerability assessments to identify and address security weaknesses.
