CVE-2025-11599: Campcodes Apartment System SQLi Flaw

CVE-2025-11599 Overview

A SQL injection vulnerability has been identified in Campcodes Online Apartment Visitor Management System 1.0. The vulnerability affects the /forgot-password.php file, where improper handling of the email parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or further system compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system through the publicly accessible forgot-password functionality.

Technical Details for CVE-2025-11599

Vulnerability Analysis

This SQL injection vulnerability exists in the password recovery functionality of the Campcodes Online Apartment Visitor Management System. The /forgot-password.php endpoint fails to properly sanitize user-supplied input in the email parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL commands that are executed against the backend database.

The vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The attack can be initiated remotely over the network without requiring any authentication or user interaction, making it particularly dangerous for internet-facing deployments.

Root Cause

The root cause of this vulnerability is the failure to implement proper input sanitization and parameterized queries in the /forgot-password.php file. The email parameter is directly concatenated into SQL query strings without escaping special characters or using prepared statements. This allows specially crafted input containing SQL metacharacters to alter the intended query logic.

Attack Vector

An attacker can exploit this vulnerability by sending a crafted HTTP request to the /forgot-password.php endpoint with a malicious payload in the email parameter. Since the vulnerability is network-accessible and requires no authentication, any remote attacker can target vulnerable installations.

The attack flow typically involves:

1. Identifying a vulnerable instance of the Online Apartment Visitor Management System
2. Crafting a malicious email parameter containing SQL injection payloads
3. Sending the request to /forgot-password.php
4. Extracting data or manipulating the database based on the injected SQL commands

Common exploitation techniques include UNION-based injection to extract database contents, boolean-based blind injection for data exfiltration, or time-based blind injection when other methods are not viable. For technical details and proof-of-concept information, refer to the GitHub CVE Issue Discussion and VulDB entry #327920.

Detection Methods for CVE-2025-11599

Indicators of Compromise

• Unusual or malformed requests to /forgot-password.php containing SQL syntax characters such as single quotes, double dashes, UNION statements, or semicolons
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database queries or access patterns originating from web application processes
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the email parameter
• Monitor web server access logs for requests to /forgot-password.php containing suspicious characters or encoded payloads
• Implement database activity monitoring to detect anomalous queries or unauthorized data access
• Use intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for the /forgot-password.php endpoint and review logs regularly for anomalous input patterns
• Configure database audit logging to track all queries executed by the web application user account
• Set up alerting for database errors or exceptions that may indicate injection attempts
• Monitor network traffic for large data transfers that could indicate successful data exfiltration

How to Mitigate CVE-2025-11599

Immediate Actions Required

• Restrict access to the /forgot-password.php endpoint using IP whitelisting or network-level controls until a patch is available
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Review and limit database user permissions to minimum required privileges
• Consider temporarily disabling the password recovery functionality if not critical to operations

Patch Information

At the time of publication, no official patch has been released by the vendor for this vulnerability. Organizations should monitor the CampCodes website for security updates and apply patches immediately when available. In the meantime, implement the recommended workarounds and mitigations to reduce risk exposure.

Workarounds

• Deploy a reverse proxy or WAF to filter and sanitize input to the vulnerable endpoint
• Modify the application code to use parameterized queries or prepared statements for all database interactions
• Implement input validation to reject email addresses containing SQL metacharacters
• Restrict database user privileges to limit the impact of successful exploitation
• Consider isolating the application in a network segment with limited access to sensitive resources

# Example: Block suspicious requests using ModSecurity WAF rules
# Add to ModSecurity configuration
SecRule ARGS:email "@detectSQLi" \
    "id:100001,\
    phase:2,\
    deny,\
    status:403,\
    msg:'SQL Injection attempt detected in email parameter',\
