CVE-2025-12853 Overview
A SQL Injection vulnerability has been identified in SourceCodester Best House Rental Management System version 1.0. This vulnerability affects the delete_house function within the /admin_class.php file, where improper handling of the ID argument allows attackers to inject malicious SQL commands. The attack can be performed remotely over the network, and the exploit has been publicly disclosed.
Critical Impact
Authenticated attackers with administrative privileges can exploit this SQL injection vulnerability to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion of rental property records.

Technical Details for CVE-2025-12853
Vulnerability Analysis
This SQL Injection vulnerability (CWE-89) exists within the administrative function responsible for deleting house records from the rental management system. The delete_house function in /admin_class.php fails to properly sanitize or parameterize the ID argument before incorporating it into SQL queries. This allows an attacker with administrative access to craft malicious input that modifies the intended SQL query structure.
The vulnerability is classified under both CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and CWE-89 (SQL Injection), indicating that user-supplied input is not properly escaped before being used in database operations.
Root Cause
The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries or prepared statements in the delete_house function. The ID parameter is directly concatenated into SQL queries without proper sanitization, allowing SQL metacharacters to escape the intended query context and execute arbitrary SQL commands.
Attack Vector
The attack can be conducted remotely over the network by an authenticated administrator. An attacker with valid administrative credentials can manipulate the ID parameter sent to the /admin_class.php endpoint during house deletion operations. By injecting SQL syntax into this parameter, the attacker can modify query logic to extract sensitive data, bypass security checks, or manipulate database records.
The vulnerability requires high-level privileges (administrative access) to exploit, which limits the attack surface but still poses significant risk in environments where administrative credentials may be compromised or shared among multiple users.
Detection Methods for CVE-2025-12853
Indicators of Compromise
- Unusual SQL error messages appearing in application logs from /admin_class.php
- Unexpected database query patterns involving the delete_house function with malformed ID values
- Evidence of database enumeration attempts such as UNION-based or error-based SQL injection signatures
- Anomalous administrative activity targeting house deletion functionality
Detection Strategies
- Implement web application firewall (WAF) rules to detect SQL injection patterns in HTTP request parameters
- Monitor application logs for requests to /admin_class.php containing SQL metacharacters (single quotes, double dashes, UNION statements)
- Deploy database activity monitoring to identify anomalous queries originating from the rental management application
- Enable verbose error logging while ensuring sensitive information is not exposed to end users
Monitoring Recommendations
- Configure intrusion detection systems (IDS) to alert on SQL injection attack signatures targeting the affected endpoint
- Implement real-time monitoring of administrative actions within the Best House Rental Management System
- Review database audit logs for unauthorized data access or modification attempts
- Set up alerts for failed database queries that may indicate injection attempts
How to Mitigate CVE-2025-12853
Immediate Actions Required
- Restrict network access to the /admin_class.php endpoint to trusted IP addresses only
- Review and audit all administrative accounts for signs of compromise
- Implement additional authentication factors for administrative access
- Consider temporarily disabling the delete_house functionality until a patch is applied
Patch Information
As of the last update, no official vendor patch has been released for SourceCodester Best House Rental Management System 1.0. Organizations using this software should monitor the SourceCodester website for security updates. Additional technical details and discussions can be found in the GitHub CVE Issue Discussion and VulDB entry #331499.
Workarounds
- Implement prepared statements or parameterized queries in the delete_house function to prevent SQL injection
- Add input validation to ensure the ID parameter contains only numeric values before processing
- Deploy a web application firewall (WAF) with SQL injection protection rules in front of the application
- Apply the principle of least privilege by limiting database user permissions for the application connection
# Example: Input validation in PHP (apply to admin_class.php)
# Ensure ID parameter is validated as integer before use
# $id = filter_input(INPUT_GET, 'id', FILTER_VALIDATE_INT);
# if ($id === false || $id === null) {
# die('Invalid ID parameter');
# }
# Use prepared statements for all database operations
