A vulnerability was determined in code-projects Online Guitar Store 1.0. Affected by this vulnerability is an unknown functionality of the file /admin/Delete_product.php. Executing manipulation of the argument del_pro can lead to sql injection. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized.
Online Guitar Store 1.0 suffers from a critical SQL injection vulnerability in /admin/Delete_product.php, allowing attackers to remotely execute arbitrary SQL commands. Successful exploitation grants attackers unauthorized access to the application's database, potentially leading to data breaches and complete system compromise. This vulnerability is publicly known and easily exploitable.
Step 1: Reconnaissance: The attacker identifies the target application, Online Guitar Store 1.0, and confirms the existence of the /admin/Delete_product.php file.
Step 2: Payload Delivery: The attacker crafts a malicious SQL injection payload, targeting the del_pro parameter. This payload is designed to execute arbitrary SQL commands.
Step 3: Request Submission: The attacker sends a specially crafted HTTP request to /admin/Delete_product.php, including the malicious payload in the del_pro parameter.
Step 4: Server-Side Processing: The vulnerable PHP script receives the request and incorporates the attacker's input directly into an SQL query without proper sanitization.
Step 5: SQL Execution: The database server executes the injected SQL code, allowing the attacker to manipulate the database.
Step 6: Data Exfiltration/Manipulation: Based on the injected SQL, the attacker can then retrieve sensitive data (e.g., user credentials, product information), modify existing data, or potentially gain complete control over the database server.
The vulnerability stems from a lack of proper input validation and sanitization of the del_pro parameter within the /admin/Delete_product.php script. The script likely directly incorporates this user-supplied input into an SQL query without escaping special characters or validating the data type. This allows an attacker to inject malicious SQL code, such as adding, deleting, or modifying data within the database. The root cause is a failure to implement prepared statements or other secure coding practices to prevent SQL injection. The absence of any form of input validation or output encoding further exacerbates the risk.
While no specific APTs are directly linked to this CVE, the ease of exploitation and public availability of the PoC make it attractive to a wide range of attackers, including script kiddies and financially motivated cybercriminals. This vulnerability could be leveraged in conjunction with other vulnerabilities to achieve a broader compromise. CISA KEV: Not Applicable (as of this report's generation, no KEV entry exists, but this could change rapidly).
Web application firewall (WAF) logs showing suspicious SQL injection attempts, such as the use of common SQL injection keywords (e.g., 'SELECT', 'UNION', 'OR', 'AND', '--').
Database server logs revealing unusual query patterns or unexpected database activity, such as unauthorized data access or modification.
Network traffic analysis identifying unusual HTTP requests to /admin/Delete_product.php with suspicious parameters.
File integrity monitoring (FIM) detecting unauthorized changes to /admin/Delete_product.php or related files.
Intrusion Detection System (IDS) alerts triggered by known SQL injection signatures.
Implement input validation and sanitization for all user-supplied data, especially the del_pro parameter. This includes validating data types and escaping special characters.
Use prepared statements or parameterized queries to prevent SQL injection. This separates the SQL code from the user-supplied data, preventing malicious code from being executed.
Apply the principle of least privilege. The database user used by the application should have only the necessary permissions to perform its tasks.
Regularly update the Online Guitar Store 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 scanning to identify and address security weaknesses.
Review and harden the web server configuration, including disabling unnecessary features and services.
Monitor application and database logs for suspicious activity.
