A vulnerability was found in itsourcecode Inventory Management System 1.0. The impacted element is an unknown function of the file /index.php?q=product. Performing manipulation of the argument PROID results in sql injection. It is possible to initiate the attack remotely. The exploit has been made public and could be used.
Inventory Management System 1.0 is vulnerable to a critical SQL injection flaw, allowing attackers to remotely compromise the system. This vulnerability, located in /index.php?q=product, enables unauthorized access to sensitive data and potential system takeover. The exploit is publicly available, posing an immediate and significant risk.
Step 1: Identify the Vulnerable Endpoint: The attacker identifies the vulnerable URL: /index.php?q=product.
Step 2: Craft the Malicious Payload: The attacker constructs a SQL injection payload designed to extract sensitive information, such as database credentials, user data, or product information. Example: PROID=1' UNION SELECT 1,username,password FROM users--
Step 3: Deliver the Payload: The attacker sends a crafted HTTP GET request to the vulnerable endpoint, including the malicious payload in the PROID parameter.
Step 4: Execute the Malicious Query: The web application receives the request and, due to the lack of input validation, incorporates the attacker's payload directly into a SQL query.
Step 5: Database Interaction: The database server executes the modified SQL query, potentially revealing sensitive information or allowing for unauthorized actions.
Step 6: Data Exfiltration/Exploitation: The attacker receives the results of the malicious query, which may include sensitive data, or uses the vulnerability to further compromise the system (e.g., creating new admin accounts, modifying product prices, or deleting data).
The vulnerability stems from insufficient input validation and sanitization of the PROID parameter within the /index.php?q=product endpoint. The application directly incorporates user-supplied data from PROID into a SQL query without proper escaping or filtering. This allows an attacker to inject malicious SQL code, manipulating the query's logic to retrieve, modify, or delete data from the database. The root cause is a missing or inadequate implementation of parameterized queries or prepared statements, a common security oversight in web application development. The lack of input validation allows for the injection of SQL commands, leading to unauthorized database access and control. The application likely uses string concatenation to build the SQL query, making it directly susceptible to SQL injection attacks. The absence of any form of input validation or output encoding further exacerbates the vulnerability.
