CVE-2025-11348 Overview
A SQL Injection vulnerability has been identified in Campcodes Online Apartment Visitor Management System version 1.0. This issue affects the processing of the /index.php file, where manipulation of the Username argument can lead to SQL injection attacks. The vulnerability can be exploited remotely, and exploit details have been publicly disclosed.
Critical Impact
Attackers can remotely exploit this SQL injection vulnerability to potentially access, modify, or delete database contents, bypass authentication mechanisms, and compromise the integrity of the visitor management system.

Technical Details for CVE-2025-11348
Vulnerability Analysis
This SQL injection vulnerability exists in the login functionality of the Campcodes Online Apartment Visitor Management System. The application fails to properly sanitize user-supplied input in the Username parameter before incorporating it into SQL queries. This allows attackers to inject malicious SQL code that gets executed by the backend database.
The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating that the application does not adequately filter or escape special characters that have meaning in SQL syntax.
Root Cause
The root cause of this vulnerability is improper input validation and lack of parameterized queries in the /index.php authentication handler. When processing login requests, the application directly concatenates user input from the Username field into SQL query strings without proper sanitization or the use of prepared statements. This allows attackers to break out of the intended query context and inject arbitrary SQL commands.
Attack Vector
The attack can be launched remotely over the network without requiring authentication or user interaction. An attacker can craft a malicious HTTP request to the /index.php endpoint containing SQL injection payloads in the Username parameter.
The exploitation involves submitting specially crafted input strings that include SQL syntax such as single quotes, comment characters, or UNION-based payloads. When the vulnerable application processes this input, the injected SQL commands are executed against the database, potentially allowing the attacker to:
- Bypass authentication and gain unauthorized access
- Extract sensitive data from the database including user credentials
- Modify or delete database records
- Potentially execute administrative database operations

Detection Methods for CVE-2025-11348
Indicators of Compromise
- Unusual or malformed requests to /index.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords in the Username parameter
- Database error messages appearing in HTTP responses that reveal SQL query structure
- Unexpected database queries or access patterns in database logs
- Authentication bypass events where users gain access without valid credentials
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in HTTP request parameters
- Monitor application logs for requests to /index.php containing suspicious payloads in the Username field
- Enable database query logging and alert on anomalous query patterns or SQL syntax errors
- Deploy intrusion detection systems with signatures for common SQL injection attack patterns
Monitoring Recommendations
- Review web server access logs for requests to /index.php with encoded or suspicious characters in POST data
- Monitor database audit logs for unauthorized data access or modification attempts
- Set up alerts for multiple failed authentication attempts followed by successful logins
- Track changes to user accounts or privilege escalation events in the application
How to Mitigate CVE-2025-11348
Immediate Actions Required
- Restrict network access to the Campcodes Online Apartment Visitor Management System to trusted IP addresses only
- Place a Web Application Firewall (WAF) in front of the application with SQL injection protection enabled
- Consider taking the application offline if it is publicly exposed until a patch or workaround is implemented
- Review database access logs for any signs of exploitation
Patch Information
No vendor patch information is currently available for this vulnerability. Organizations using Campcodes Online Apartment Visitor Management System 1.0 should contact the vendor directly for remediation guidance. Monitor the CampCodes website for security updates and patch releases.
Workarounds
- Implement input validation at the application level to reject special characters in the Username field
- Deploy a WAF with SQL injection detection rules to filter malicious requests before they reach the application
- Restrict database user permissions to limit the impact of successful SQL injection attacks
- Consider implementing a reverse proxy with request filtering capabilities to sanitize input
# Example WAF rule configuration (ModSecurity)
SecRule ARGS:Username "@detectSQLi" \
"id:1001,\
