A vulnerability was found in code-projects Online Guitar Store 1.0. Affected is an unknown function of the file /admin/Create_product.php. Performing manipulation of the argument dre_title results in sql injection. The attack is possible to be carried out remotely. The exploit has been made public and could be used.
Online Guitar Store 1.0 is vulnerable to a critical SQL injection flaw, allowing attackers to remotely compromise the database. This vulnerability, located in /admin/Create_product.php, enables unauthorized access to sensitive data and potential system takeover. The exploit is publicly available, posing a significant risk of widespread exploitation.
Step 1: Payload Delivery: An attacker crafts a malicious SQL injection payload designed to be inserted into the dre_title parameter of the /admin/Create_product.php file.
Step 2: Request Submission: The attacker submits a specially crafted HTTP POST request to the vulnerable endpoint, including the malicious payload in the dre_title parameter.
Step 3: Query Execution: The server-side PHP script processes the request and, due to the lack of input validation, directly incorporates the attacker's payload into an SQL query.
Step 4: Database Manipulation: The database server executes the modified SQL query, which now includes the attacker's malicious code. This could lead to data retrieval, modification, or deletion, depending on the payload.
Step 5: Information Disclosure/System Compromise: The attacker leverages the results of the malicious SQL query to gain unauthorized access to sensitive information (e.g., usernames, passwords, product details) or to further compromise the system (e.g., by creating a backdoor user or escalating privileges).
The vulnerability stems from insufficient input validation and sanitization of the dre_title parameter within the /admin/Create_product.php file. The application directly incorporates user-supplied data from the dre_title parameter into an SQL query without proper escaping or filtering. This allows an attacker to inject malicious SQL code, altering the intended query and potentially retrieving, modifying, or deleting data from the database. The root cause is a lack of parameterized queries or prepared statements, which would mitigate the risk of SQL injection. The specific flaw likely resides in the function responsible for processing the product creation form data and constructing the SQL query to insert the new product information into the database. The absence of input validation allows attackers to craft malicious payloads that manipulate the database query.
While no specific APTs are directly linked to this CVE at this time, the public availability of the exploit makes it attractive to a wide range of attackers, including script kiddies and opportunistic attackers. This vulnerability is not yet listed on the CISA KEV catalog, but its potential for widespread impact warrants close monitoring.
Web server logs analysis for unusual POST requests to /admin/Create_product.php with suspicious dre_title values (e.g., containing SQL keywords like SELECT, UNION, DROP, UPDATE, etc.).
Database server logs analysis for unusual queries originating from the web server, particularly those involving unexpected table modifications or data retrieval.
Network traffic analysis for suspicious HTTP POST requests with SQL injection payloads, using tools like Wireshark or Suricata.
File integrity monitoring to detect any unauthorized modifications to /admin/Create_product.php or related files.
Implement a Web Application Firewall (WAF) with SQL injection detection rules.
Implement parameterized queries or prepared statements to prevent SQL injection. This ensures that user-supplied data is treated as data, not as executable code.
Thoroughly validate and sanitize all user inputs, including the dre_title parameter, to remove or escape potentially malicious characters.
Implement a Web Application Firewall (WAF) to filter malicious requests.
Apply the principle of least privilege to database users, restricting their access to only the necessary tables and operations.
Regularly update the Online Guitar Store software to the latest version, which may include patches for this vulnerability.
Conduct regular penetration testing and vulnerability assessments to identify and address security weaknesses.
