A vulnerability has been found in code-projects Online Guitar Store 1.0. This impacts an unknown function of the file /admin/Create_category.php. Such manipulation of the argument dre_Ctitle leads to sql injection. The attack can be executed remotely. The exploit has been disclosed to the public and may be used.
Online Guitar Store 1.0 is vulnerable to a critical SQL injection flaw, allowing attackers to remotely inject malicious code into the application's database. This vulnerability, located in /admin/Create_category.php, could lead to complete system compromise, including data theft and server control.
Step 1: Payload Delivery: An attacker crafts a malicious SQL payload designed to exploit the vulnerability.
Step 2: Request Construction: The attacker constructs an HTTP POST request to /admin/Create_category.php. The malicious SQL payload is injected into the dre_Ctitle parameter of the POST request.
Step 3: Server-Side Processing: The vulnerable PHP script receives the request and processes the dre_Ctitle parameter.
Step 4: Query Execution: The script incorporates the attacker-controlled dre_Ctitle value directly into an SQL query without proper sanitization.
Step 5: Database Manipulation: The database server executes the malicious SQL query, allowing the attacker to perform actions such as retrieving sensitive data, modifying existing data, or creating new administrative accounts.
Step 6: Result Retrieval (Optional): Depending on the payload, the attacker may retrieve the results of their query, confirming successful exploitation and potentially exfiltrating data.
The vulnerability stems from insufficient input validation and sanitization of the dre_Ctitle parameter within the /admin/Create_category.php file. The application likely directly incorporates user-supplied input into an SQL query without proper escaping or filtering. This allows an attacker to craft a malicious SQL payload that, when executed, can manipulate the database, potentially leading to unauthorized access, data modification, or complete server takeover. The root cause is a failure to implement proper input validation and parameterized queries, leading to a classic SQL injection vulnerability.
While no specific APTs are directly linked to this CVE at this time, the ease of exploitation makes it attractive to a wide range of threat actors, including those seeking to steal data or establish a foothold within the target network. The vulnerability's potential for remote code execution and data exfiltration makes it a high-priority target. CISA KEV status: Not yet listed, but likely to be added soon given the public disclosure and potential impact.
Web Application Firewall (WAF) logs showing suspicious SQL injection attempts, such as the use of single quotes, double quotes, or SQL keywords like 'SELECT', 'UNION', 'DROP', or 'UPDATE' in the dre_Ctitle parameter.
Network traffic analysis revealing unusual POST requests to /admin/Create_category.php with potentially malicious payloads in the dre_Ctitle parameter.
Database server logs indicating unexpected queries or errors related to the Create_category.php script.
File integrity monitoring (FIM) detecting unauthorized modifications to the /admin/Create_category.php file or related database files.
Security Information and Event Management (SIEM) systems configured to alert on SQL injection attempts based on signature-based or behavior-based detection rules.
Implement input validation and sanitization on the dre_Ctitle parameter to ensure that only expected data is accepted. This includes filtering out special characters and validating the data type.
Use parameterized queries or prepared statements to prevent SQL injection. This approach separates the SQL code from the user-supplied data, preventing malicious code from being interpreted as part of the query.
Apply the latest security patches provided by the vendor. This is the most direct way to address the vulnerability.
Implement a Web Application Firewall (WAF) to filter malicious requests before they reach the vulnerable application.
Regularly scan the application for vulnerabilities using automated tools.
Review and harden the database server configuration, including access controls and auditing.
Implement the principle of least privilege for database users, granting only the necessary permissions.
Conduct regular security audits and penetration testing to identify and address vulnerabilities.
