CVE-2025-7119: Campcodes Complaint Management SQLi Flaw

CVE-2025-7119 Overview

A critical SQL injection vulnerability has been identified in Campcodes Complaint Management System version 1.0. The vulnerability exists in the /users/index.php file where the Username argument is not properly sanitized before being used in SQL queries. This flaw allows remote attackers to inject malicious SQL commands through the Username parameter, potentially leading to unauthorized access to the database, data exfiltration, and manipulation of stored information.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or bypass authentication mechanisms in the Complaint Management System.

Affected Products

• Campcodes Complaint Management System 1.0

Technical Details for CVE-2025-7119

Vulnerability Analysis

This SQL injection vulnerability in Campcodes Complaint Management System arises from improper handling of user-supplied input in the /users/index.php endpoint. When processing the Username argument, the application fails to properly sanitize or parameterize the input before incorporating it into SQL queries. This allows an attacker to craft malicious input that modifies the intended SQL query structure, enabling unauthorized database operations.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where user input is not properly validated before being processed by an interpreter. A public proof-of-concept exploit has been disclosed, increasing the risk of active exploitation.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and sanitization in the /users/index.php file. The application directly incorporates user-supplied data from the Username parameter into SQL queries without using prepared statements or parameterized queries. This allows special SQL characters and commands to be interpreted as part of the query rather than as literal data values.

Attack Vector

The attack can be launched remotely over the network without requiring authentication or user interaction. An attacker submits a specially crafted Username value to the /users/index.php endpoint containing SQL injection payloads. The vulnerable application processes this input directly in SQL queries, allowing the attacker to:

• Extract sensitive information from the database
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially escalate privileges within the application

The vulnerability mechanism involves injecting SQL syntax through the Username parameter. When the application constructs a query using unsanitized input, attackers can append additional SQL commands or modify query logic using techniques such as UNION-based injection, boolean-based blind injection, or time-based blind injection. For technical details on the exploitation methodology, refer to the GitHub PoC Issue #42.

Detection Methods for CVE-2025-7119

Indicators of Compromise

• Unusual or malformed values in the Username parameter containing SQL keywords such as UNION, SELECT, DROP, OR 1=1, or comment sequences (--, /*)
• Database error messages appearing in HTTP responses indicating SQL syntax errors
• Unexpected database queries or access patterns in database logs
• Anomalous authentication successes without valid credentials

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the Username parameter
• Enable detailed logging on the /users/index.php endpoint to capture all input values
• Implement database activity monitoring to detect unusual query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor HTTP request logs for requests to /users/index.php containing suspicious characters or SQL keywords
• Set up alerts for database errors or exceptions that may indicate injection attempts
• Review authentication logs for anomalous successful logins that may indicate authentication bypass
• Implement real-time monitoring for bulk data extraction attempts from the database

How to Mitigate CVE-2025-7119

Immediate Actions Required

• Remove or restrict access to the Campcodes Complaint Management System until a patch is available
• Implement input validation on the Username parameter to reject malicious characters
• Deploy a Web Application Firewall (WAF) with SQL injection protection in front of the application
• Review database logs for any signs of previous exploitation attempts

Patch Information

As of the last update on July 9, 2025, no official patch has been released by Campcodes for this vulnerability. Organizations should monitor the CampCodes official website for security updates. Additional vulnerability details are available through VulDB #315031.

Workarounds

• Implement parameterized queries or prepared statements in the affected /users/index.php file to prevent SQL injection
• Deploy a reverse proxy or WAF configured to sanitize and validate all input to the vulnerable endpoint
• Restrict network access to the Complaint Management System to trusted IP addresses only
• Apply the principle of least privilege to the database user account used by the application to minimize potential impact
