CVE-2024-9085: Restaurant Reservation System SQLi Flaw

CVE-2024-9085 Overview

A SQL injection vulnerability has been identified in code-projects Restaurant Reservation System version 1.0. This vulnerability exists in the index.php file and can be exploited through manipulation of the date parameter. The flaw allows remote attackers to inject malicious SQL statements, potentially compromising the underlying database and exposing sensitive information. The initial researcher advisory incorrectly identified sid as the affected parameter, but subsequent analysis confirmed that the date parameter is the actual attack vector.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data from the database, modify or delete records, and potentially gain unauthorized access to the entire reservation system.

Technical Details for CVE-2024-9085

Vulnerability Analysis

This vulnerability is classified as CWE-89: Improper Neutralization of Special Elements used in an SQL Command (SQL Injection). The application fails to properly sanitize user-supplied input in the date parameter before incorporating it into SQL queries executed against the backend database.

SQL injection vulnerabilities in reservation systems are particularly concerning because these applications typically store customer personal information, contact details, and potentially payment data. An attacker exploiting this vulnerability could extract the entire customer database, modify reservation records, or use the compromised database server as a pivot point for further attacks on the network infrastructure.

The vulnerability is exploitable remotely without authentication, making it accessible to any attacker who can reach the application over the network. The publicly disclosed nature of this exploit increases the risk of opportunistic attacks against unpatched systems.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries or prepared statements in the index.php file. When user input from the date parameter is directly concatenated into SQL query strings without proper sanitization or escaping, it allows attackers to manipulate the query logic by injecting SQL metacharacters and commands.

Attack Vector

The attack can be initiated remotely over the network by sending crafted HTTP requests to the index.php endpoint with malicious payloads in the date parameter. The exploitation requires no authentication or special privileges, making it accessible to any remote attacker.

An attacker would typically craft requests containing SQL injection payloads such as single quotes, UNION statements, or time-based blind injection techniques to extract data or manipulate the database. The exploit has been publicly disclosed, providing attackers with ready-made attack techniques.

Detection Methods for CVE-2024-9085

Indicators of Compromise

• Unusual SQL error messages appearing in application logs or web responses containing database-specific syntax errors
• HTTP request logs showing suspicious payloads in the date parameter, including SQL keywords like UNION, SELECT, OR 1=1, or single quote characters
• Unexpected database queries or access patterns in database audit logs
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the date parameter
• Implement application-level logging to capture all requests to index.php with parameter values for forensic analysis
• Configure database activity monitoring to alert on unusual query patterns or bulk data extraction attempts
• Use intrusion detection systems (IDS) with SQL injection signature detection capabilities

Monitoring Recommendations

• Enable verbose logging for the Restaurant Reservation System application and review logs regularly
• Monitor database server logs for failed login attempts, unusual queries, or privilege escalation attempts
• Set up alerts for any access attempts to sensitive database tables containing customer information
• Implement network traffic analysis to detect SQL injection attack patterns in HTTP traffic

How to Mitigate CVE-2024-9085

Immediate Actions Required

• Take the affected Restaurant Reservation System offline or restrict access until a patch can be applied
• Implement a Web Application Firewall (WAF) with SQL injection blocking rules as an interim protective measure
• Review application and database logs for any evidence of exploitation attempts
• Audit the database for unauthorized changes or data exfiltration indicators

Patch Information

No official patch information has been released by the vendor at this time. Organizations should monitor the Code Projects Resource Hub for updates. Additional technical details about this vulnerability can be found in the GitHub Issue Discussion and VulDB #278261.

Workarounds

• Implement input validation on the date parameter to accept only properly formatted date values
• Modify the application code to use parameterized queries or prepared statements instead of string concatenation
• Deploy a reverse proxy or WAF in front of the application to filter malicious requests
• Restrict network access to the application to trusted IP ranges only until a proper fix is available
• Consider migrating to a more actively maintained reservation system with better security practices
