CVE-2025-7122: Campcodes Complaint Management SQL Injection

CVE-2025-7122 Overview

A critical SQL injection vulnerability has been identified in Campcodes Complaint Management System version 1.0. The vulnerability exists in the /admin/index.php file where the Username parameter is improperly sanitized, allowing attackers to inject malicious SQL queries. This flaw enables unauthenticated remote attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data, modify database contents, or potentially escalate to remote code execution depending on database configuration.

Technical Details for CVE-2025-7122

Vulnerability Analysis

This SQL injection vulnerability occurs in the administrative login interface of the Campcodes Complaint Management System. The application fails to properly sanitize user-supplied input in the Username parameter before incorporating it into SQL queries. When a user submits credentials through the /admin/index.php login form, the application directly concatenates the username value into the SQL query without using parameterized queries or adequate input validation.

The vulnerability allows attackers to inject arbitrary SQL code through the login form, enabling them to bypass authentication mechanisms entirely or extract sensitive information from the database. Given the administrative nature of the affected endpoint, successful exploitation could grant attackers full administrative access to the complaint management system.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries in the authentication mechanism. The Username parameter is directly interpolated into SQL statements without sanitization, escaping, or the use of prepared statements. This classic injection pattern (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) allows attackers to break out of the intended query structure and execute arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads in the Username parameter of the login form at /admin/index.php. Common exploitation techniques include:

The vulnerability is exploited by submitting specially crafted input through the administrative login form. An attacker would navigate to the /admin/index.php endpoint and inject SQL syntax into the Username field. Typical payloads might include boolean-based blind injection techniques, UNION-based queries to extract data from other tables, or time-based blind injection for scenarios where direct output is not visible. The exploit has been publicly disclosed, increasing the risk of widespread exploitation. For detailed technical information, refer to the GitHub PoC Issue.

Detection Methods for CVE-2025-7122

Indicators of Compromise

• HTTP POST requests to /admin/index.php containing SQL metacharacters such as single quotes, double dashes, semicolons, or UNION keywords in the Username parameter
• Database error messages in application logs indicating syntax errors or unexpected query behavior
• Unusual database query patterns or execution of commands not typical of normal application behavior
• Unexpected administrative access or new admin accounts created without authorization

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in POST parameters
• Monitor application and database logs for SQL syntax errors, unusual query patterns, or authentication anomalies
• Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns targeting login endpoints
• Review access logs for repeated failed login attempts followed by successful authentication, which may indicate injection-based bypass

Monitoring Recommendations

• Enable detailed logging on the /admin/index.php endpoint to capture all authentication attempts and parameter values
• Configure database query logging to identify anomalous or malformed queries
• Set up alerts for multiple failed authentication attempts from single IP addresses or unusual geographic locations
• Monitor for unauthorized database modifications or data exfiltration patterns

How to Mitigate CVE-2025-7122

Immediate Actions Required

• Restrict access to the /admin/index.php endpoint by IP whitelist or VPN requirements until a patch is available
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Review database user permissions to ensure the application uses a least-privilege account
• Audit database logs for any signs of prior exploitation

Patch Information

No official patch has been released by Campcodes at the time of this publication. Organizations should monitor the CampCodes website for security updates. Additional vulnerability tracking information is available through VulDB #315034.

Workarounds

• Implement input validation on the Username parameter to reject any input containing SQL metacharacters
• Use a Web Application Firewall to filter malicious requests before they reach the application
• Restrict network access to the administrative interface using firewall rules or VPN requirements
• If source code access is available, modify the authentication logic to use parameterized queries or prepared statements

# Example: Restrict admin access via .htaccess
<Files "index.php">
    <RequireAll>
        Require ip 10.0.0.0/8
        Require ip 192.168.0.0/16
    </RequireAll>
</Files>
