SQL Injection Vulnerability in Simple Food Order System 1.0

A SQL injection vulnerability has been identified in the code-projects Simple Food Order System version 1.0. The vulnerability resides within the register-router.php file, specifically affecting the handling of the ‘Name’ argument. An attacker can remotely exploit this weakness by manipulating the ‘Name’ parameter, leading to arbitrary SQL execution. Given the public availability of exploit code, the risk of active exploitation is elevated. This vulnerability is particularly concerning as it could allow attackers to compromise the application’s database, potentially leading to data theft, modification, or complete system takeover. Successful exploitation allows an unauthenticated attacker to execute arbitrary SQL queries against the backend database.

Attack Chain

1. An attacker identifies a vulnerable Simple Food Order System 1.0 instance exposed to the internet.
2. The attacker crafts a malicious HTTP request targeting the register-router.php endpoint.
3. Within the request, the attacker injects SQL code into the Name parameter.
4. The application fails to properly sanitize the injected SQL code, passing it directly to the database.
5. The database executes the malicious SQL query, potentially allowing the attacker to bypass authentication or access sensitive data.
6. The attacker retrieves sensitive information from the database, such as user credentials or order details.
7. Using the stolen credentials, the attacker gains unauthorized access to the application’s administrative panel.
8. The attacker modifies data within the database, disrupting services or exfiltrating sensitive information.

Impact

Successful exploitation of this SQL injection vulnerability can have significant consequences. Attackers could gain unauthorized access to sensitive customer data, including personal information and financial details. This data could be used for identity theft, fraud, or sold on the dark web. The compromise of the database could also lead to data corruption, service disruption, or complete system takeover. Given the ease of exploitation, a large number of installations are potentially at risk.

Recommendation

• Apply appropriate input validation and sanitization to the Name parameter in register-router.php to prevent SQL injection attacks.
• Deploy the Sigma rule Detect Suspicious SQL Injection Attempts to monitor for exploitation attempts targeting this vulnerability.
• Monitor web server logs for suspicious requests containing SQL syntax targeting the register-router.php endpoint (webserver log source).
• Review and harden database server configurations to prevent unauthorized access.
• Consider implementing a web application firewall (WAF) to filter out malicious requests.
