CVE-2025-9594 Overview
A SQL injection vulnerability has been discovered in itsourcecode Apartment Management System version 1.0. The vulnerability exists in the /report/complain_info.php file where improper handling of the vid parameter allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive tenant information, modify database records, or potentially gain unauthorized access to the underlying system through database-level attacks.

Technical Details for CVE-2025-9594
Vulnerability Analysis
This vulnerability stems from insufficient input validation in the complaint information reporting functionality of the Apartment Management System. The application fails to properly sanitize user-supplied input to the vid parameter before incorporating it into SQL queries. This lack of parameterized queries or proper input escaping allows attackers to break out of the intended query structure and execute arbitrary SQL commands against the backend database.
The affected endpoint /report/complain_info.php appears to handle complaint-related data retrieval, where the vid parameter likely references a specific complaint or violation record identifier. Without proper validation, an attacker can craft malicious input that modifies the SQL query logic.
Root Cause
The root cause of this vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as injection. The application directly concatenates user input into SQL queries without implementing prepared statements, parameterized queries, or adequate input sanitization. This fundamental security flaw 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 executed remotely over the network without requiring authentication or user interaction. An attacker can craft HTTP requests to the vulnerable endpoint with malicious SQL payload in the vid parameter. The exploitation process typically involves:
- Identifying the injection point in /report/complain_info.php
- Determining the database type and structure through error-based or blind SQL injection techniques
- Extracting sensitive data such as tenant personal information, payment records, or administrative credentials
- Potentially escalating the attack to modify or delete database records
The vulnerability mechanism involves manipulating the vid parameter in HTTP requests to the /report/complain_info.php endpoint. Attackers can inject SQL syntax that alters the query's intended behavior, potentially using techniques such as UNION-based injection to extract data from other tables, or boolean-based blind injection to enumerate database contents. For detailed technical analysis, refer to the GitHub CVE Issue Discussion and VulDB #321768.
Detection Methods for CVE-2025-9594
Indicators of Compromise
- Unusual SQL error messages in web server logs originating from /report/complain_info.php
- HTTP requests containing SQL keywords (UNION, SELECT, INSERT, DROP) in the vid parameter
- Database query logs showing malformed or unexpected queries from the complaint reporting module
- Abnormal database access patterns or bulk data extraction activities
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the vid parameter
- Monitor application logs for requests to /report/complain_info.php with suspicious parameter values
- Deploy database activity monitoring to detect unusual query patterns or unauthorized data access
- Use intrusion detection systems (IDS) with SQL injection signature rules
Monitoring Recommendations
- Enable verbose logging for the Apartment Management System web application
- Configure database audit logging to track all queries executed against tenant and complaint tables
- Set up alerting for failed login attempts and privilege escalation indicators
- Regularly review access logs for the /report/ directory and related PHP files
How to Mitigate CVE-2025-9594
Immediate Actions Required
- Restrict network access to the Apartment Management System to trusted IP addresses only
- Implement Web Application Firewall rules to filter malicious SQL injection attempts
- Consider temporarily disabling or restricting access to the /report/complain_info.php endpoint
- Back up the database and audit for any signs of unauthorized access or data modification
- Review application logs for evidence of exploitation attempts
Patch Information
As of the last update on 2025-09-03, no official vendor patch has been released for this vulnerability. Organizations using the affected Apartment Management System should monitor the IT Source Code website for security updates. In the absence of an official patch, implementing the workarounds and compensating controls below is strongly recommended.
For additional technical details and vulnerability tracking, refer to:
Workarounds
- Implement input validation at the web server level to reject requests with suspicious characters in the vid parameter
- Deploy a reverse proxy or WAF with SQL injection filtering capabilities in front of the application
- Modify the application code to use parameterized queries or prepared statements if source code access is available
- Apply the principle of least privilege to the database user account used by the application
- Consider migrating to a more actively maintained apartment management solution
# Example .htaccess rule to block common SQL injection patterns
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|drop|delete|update|concat|benchmark|sleep)(.*)$ [NC]
RewriteRule ^report/complain_info\.php$ - [F,L]
</IfModule>
