CVE-2025-11334: Campcodes Visitor Management SQLi Flaw

CVE-2025-11334 Overview

A SQL injection vulnerability has been discovered in Campcodes Online Apartment Visitor Management System version 1.0. The vulnerability exists in the /visitor-detail.php file where the editid parameter is not properly sanitized before being used in SQL queries. This allows remote attackers to inject malicious SQL statements and potentially compromise the underlying database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive visitor data, modify database records, or potentially gain unauthorized access to the apartment management system's backend database.

Technical Details for CVE-2025-11334

Vulnerability Analysis

This SQL injection vulnerability stems from improper input validation in the visitor detail functionality of the apartment management system. The editid parameter in /visitor-detail.php accepts user-supplied input that is directly incorporated into SQL queries without adequate sanitization or parameterization. This classic injection pattern allows attackers to break out of the intended query context and execute arbitrary SQL commands.

The vulnerability is remotely exploitable without authentication, meaning any attacker with network access to the application can attempt exploitation. The public disclosure of exploitation techniques increases the risk profile of this vulnerability for organizations running unpatched versions.

Root Cause

The root cause is CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), specifically manifesting as SQL injection. The application fails to properly validate, sanitize, or parameterize user input from the editid parameter before constructing SQL queries. This allows special characters and SQL syntax to be interpreted as database commands rather than literal data values.

Attack Vector

The attack is conducted remotely over the network by manipulating HTTP requests to the /visitor-detail.php endpoint. An attacker crafts malicious values for the editid parameter that include SQL injection payloads. When the application processes these requests, the injected SQL commands are executed against the database with the privileges of the application's database user.

Common attack scenarios include:

• Using UNION-based injection to extract data from other database tables
• Boolean-based blind injection to enumerate database contents
• Time-based blind injection when direct output is not visible
• Stacked queries to perform INSERT, UPDATE, or DELETE operations

Detection Methods for CVE-2025-11334

Indicators of Compromise

• HTTP requests to /visitor-detail.php containing SQL syntax characters in the editid parameter (e.g., single quotes, semicolons, UNION keywords)
• Database error messages in application logs indicating malformed SQL queries
• Unusual database query patterns or execution times from the web application's database user
• Access logs showing repeated requests to /visitor-detail.php with varying editid values

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the editid parameter
• Configure database activity monitoring to alert on anomalous query patterns from the application
• Enable detailed application logging and monitor for SQL-related error messages
• Deploy intrusion detection system (IDS) signatures targeting common SQL injection payloads

Monitoring Recommendations

• Monitor HTTP traffic to /visitor-detail.php for requests containing SQL injection indicators
• Review database audit logs for unauthorized data access or modification attempts
• Set up alerting for database errors that may indicate exploitation attempts
• Correlate web server access logs with database query logs to identify suspicious activity chains

How to Mitigate CVE-2025-11334

Immediate Actions Required

• Restrict network access to the affected application to trusted users and networks only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Review application logs and database audit logs for signs of exploitation
• Consider temporarily disabling the visitor detail functionality until a patch is available

Patch Information

As of the last modification date (February 24, 2026), no official vendor patch has been publicly documented in the available CVE data. Organizations should monitor the CampCodes website for security updates. Review VulDB Submit ID #664583 for the latest vulnerability status and any vendor responses.

Workarounds

• Implement input validation on the editid parameter to accept only numeric values
• Deploy a WAF or reverse proxy with SQL injection filtering capabilities in front of the application
• Apply the principle of least privilege to the database user account used by the application
• Implement prepared statements or parameterized queries at the application code level if source code modification is possible
• Consider network segmentation to isolate the vulnerable application from sensitive network resources
