CVE-2024-5094 Overview
A SQL Injection vulnerability has been identified in SourceCodester Best House Rental Management System version 1.0. This vulnerability exists within the view_payment.php file, where improper handling of the id parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or complete database compromise.
Critical Impact
Unauthenticated remote attackers can exploit this SQL injection flaw to extract sensitive data, modify database records, or potentially gain further access to the underlying system through database manipulation techniques.

Technical Details for CVE-2024-5094
Vulnerability Analysis
This vulnerability is a classic SQL Injection (CWE-89) flaw that arises from improper neutralization of special elements used in SQL commands. The view_payment.php file accepts user-controlled input through the id parameter without adequate sanitization or parameterized queries. When a user submits a request to view payment details, the application directly concatenates the id parameter value into a SQL query string, allowing attackers to manipulate the query logic.
The exploit has been publicly disclosed and documentation is available, increasing the risk of active exploitation. Attackers can leverage this vulnerability to perform various SQL injection attacks including UNION-based attacks to extract data from other tables, boolean-based blind injection to enumerate database contents, or time-based blind injection for data exfiltration when direct output is not available.
Root Cause
The root cause of this vulnerability is the failure to properly sanitize user-supplied input before incorporating it into SQL queries. The view_payment.php script directly uses the id parameter value in database queries without implementing prepared statements, parameterized queries, or input validation. This allows special SQL characters and commands to be interpreted as part of the query structure rather than as literal data values.
Attack Vector
The attack can be initiated remotely over the network without requiring any authentication or special privileges. An attacker simply needs to craft a malicious HTTP request to the view_payment.php endpoint with a specially crafted id parameter containing SQL injection payloads.
The vulnerability is exploited by manipulating the id parameter in requests to view_payment.php. An attacker can append SQL syntax to the parameter value to alter the query's behavior. For example, injecting a single quote followed by SQL commands can allow data extraction from other database tables or bypass application logic. Detailed proof-of-concept information is available in the GitHub PoC Repository.
Detection Methods for CVE-2024-5094
Indicators of Compromise
- Unusual or malformed requests to view_payment.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
- Database error messages appearing in application logs or HTTP responses indicating SQL syntax errors
- Unexpected database queries in database audit logs, especially those accessing multiple tables or using UNION statements
- Anomalous traffic patterns to the vulnerable endpoint with varying id parameter values
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the id parameter
- Enable database query logging and monitor for suspicious queries originating from the web application
- Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
- Conduct regular security scans of web application endpoints for injection vulnerabilities
Monitoring Recommendations
- Monitor HTTP access logs for requests to view_payment.php with anomalous id parameter values
- Set up alerts for database errors that may indicate injection attempts
- Review application and web server logs for patterns consistent with automated scanning or exploitation tools
- Track database query execution times for anomalies that may indicate time-based blind SQL injection attempts
How to Mitigate CVE-2024-5094
Immediate Actions Required
- Restrict access to the vulnerable view_payment.php endpoint until a fix can be applied
- Implement Web Application Firewall rules to filter malicious SQL injection payloads targeting the id parameter
- Review application code and implement input validation and parameterized queries
- Audit database access logs for signs of prior exploitation
Patch Information
No official vendor patch has been publicly announced for this vulnerability. Users of the SourceCodester Best House Rental Management System should contact the vendor or check for updates. Additional vulnerability information is available at VulDB #265073.
Workarounds
- Implement prepared statements or parameterized queries in the view_payment.php file to prevent SQL injection
- Apply strict input validation to ensure the id parameter only accepts expected integer values
- Deploy a WAF in front of the application to filter malicious requests
- Consider network-level restrictions to limit access to the application to trusted IP addresses only
# Example: Restricting access to vulnerable endpoint via .htaccess
<Files "view_payment.php">
Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24
