CVE-2024-6042 Overview
A SQL injection vulnerability has been identified in itsourcecode Real Estate Management System version 1.0. This vulnerability exists within the property-detail.php file, where improper sanitization of the id parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, or complete database compromise.
Critical Impact
Unauthenticated remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially escalate to full system compromise through the exposed property-detail.php endpoint.

Technical Details for CVE-2024-6042
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) affects the property-detail.php file in the Real Estate Management System. The vulnerability arises from the application's failure to properly validate and sanitize user-supplied input through the id parameter before incorporating it into SQL queries. Since the application accepts arbitrary input and directly concatenates it into database queries, an attacker can manipulate the query logic to perform unauthorized operations.
The vulnerability is particularly concerning because it can be exploited remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious requests to extract sensitive property listings, customer information, financial data, or administrative credentials stored in the database.
Root Cause
The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries or prepared statements in the property-detail.php file. When the id parameter is received from user input, it is likely concatenated directly into SQL query strings without proper escaping or type validation. This classic SQL injection pattern allows attackers to break out of the intended query structure and execute arbitrary SQL commands.
Attack Vector
The attack can be launched remotely by sending crafted HTTP requests to the vulnerable property-detail.php endpoint. An attacker would manipulate the id parameter in the URL or POST request body to inject SQL syntax. Common exploitation techniques include:
- Union-based injection: Appending UNION SELECT statements to extract data from other tables
- Error-based injection: Triggering database errors that reveal schema information
- Blind injection: Using boolean or time-based techniques to infer data character by character
- Stacked queries: Executing additional SQL statements to modify or delete data
The vulnerability allows attackers to bypass authentication, enumerate database contents, extract sensitive information, and potentially gain administrative access to the application.
Detection Methods for CVE-2024-6042
Indicators of Compromise
- Unusual SQL syntax patterns in web server access logs targeting property-detail.php
- Requests to property-detail.php containing special characters such as single quotes, semicolons, or SQL keywords in the id parameter
- Database error messages appearing in application responses or logs
- Unexpected database queries or data extraction attempts logged by database monitoring tools
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to property-detail.php
- Monitor web server logs for requests containing SQL keywords (SELECT, UNION, INSERT, DROP, etc.) in the id parameter
- Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access
- Use intrusion detection systems (IDS) with SQL injection signature rules
Monitoring Recommendations
- Enable detailed logging on the web server and database to capture all requests and queries
- Set up alerts for database errors or unusual query execution times
- Monitor for bulk data extraction patterns that may indicate successful exploitation
- Review access patterns to property-detail.php for anomalous request volumes or parameter values
How to Mitigate CVE-2024-6042
Immediate Actions Required
- Remove or disable access to the Real Estate Management System until a patch is applied
- Implement input validation to restrict the id parameter to numeric values only
- Deploy a Web Application Firewall (WAF) with SQL injection protection rules
- Review database logs for signs of previous exploitation attempts
Patch Information
As of the last update on 2024-11-21, no official vendor patch has been released for this vulnerability. Organizations using the affected Real Estate Management System should contact the developer or consider implementing the workarounds below. Additional technical information is available through the VulDB entry #268766 and the GitHub CVE Issue Discussion.
Workarounds
- Implement prepared statements or parameterized queries in property-detail.php to prevent SQL injection
- Add strict input validation to ensure the id parameter only accepts integer values
- Deploy a WAF with SQL injection detection capabilities in front of the application
- Restrict network access to the application to trusted IP ranges only
- Consider taking the application offline until proper security controls are implemented
# Example: Apache .htaccess rule to restrict id parameter to numeric values
RewriteEngine On
RewriteCond %{QUERY_STRING} id=([^0-9]+) [NC]
RewriteRule ^property-detail\.php$ - [F,L]
