CVE-2025-9744: Campcodes Loan Management System SQLI Flaw

CVE-2025-9744 Overview

A SQL injection vulnerability has been identified in Campcodes Online Loan Management System version 1.0. The vulnerability exists in an unknown function of the file /ajax.php?action=login, where manipulation of the Username argument can lead to SQL injection attacks. This weakness allows remote attackers to execute arbitrary SQL commands against the backend database, potentially compromising sensitive financial and user data stored within the loan management application.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive loan and customer data, modify database records, or potentially gain unauthorized access to the underlying system.

Affected Products

• Campcodes Online Loan Management System 1.0

Technical Details for CVE-2025-9744

Vulnerability Analysis

This vulnerability stems from improper input validation and lack of parameterized queries in the login functionality of the Campcodes Online Loan Management System. The affected endpoint /ajax.php?action=login processes user-supplied input through the Username parameter without adequate sanitization, allowing attackers to inject malicious SQL statements directly into database queries.

The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). These weaknesses indicate that the application fails to properly sanitize or escape user input before incorporating it into SQL queries.

Since the attack vector is network-based and requires no authentication or user interaction, any remote attacker can potentially exploit this vulnerability to manipulate database queries. The publicly available nature of the exploit information increases the risk of active exploitation.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) in the login processing function. When user-supplied data from the Username field is concatenated directly into SQL queries without sanitization, attackers can break out of the intended query structure and inject their own SQL commands.

Attack Vector

The attack is conducted remotely over the network by sending specially crafted HTTP requests to the /ajax.php?action=login endpoint. An attacker manipulates the Username parameter to inject SQL syntax that alters the intended query behavior.

The vulnerability can be exploited to bypass authentication by injecting SQL logic that always evaluates to true, or to extract database contents through UNION-based or error-based SQL injection techniques. Given the context of a loan management system, attackers could potentially access sensitive financial records, personal identification information, loan details, and customer credentials.

Detection Methods for CVE-2025-9744

Indicators of Compromise

• Unusual SQL error messages in application logs originating from /ajax.php?action=login
• HTTP requests to /ajax.php?action=login containing SQL syntax characters such as single quotes, double dashes, or UNION keywords in the Username parameter
• Failed login attempts with abnormally long or malformed username values
• Database query logs showing unexpected queries or access patterns against user authentication tables

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block SQL injection patterns in HTTP POST parameters targeting the login endpoint
• Implement intrusion detection system (IDS) signatures for common SQL injection payloads in authentication requests
• Enable detailed logging on the web server and database to capture suspicious query patterns
• Use SentinelOne Singularity Platform to monitor for anomalous database access patterns and potential data exfiltration attempts

Monitoring Recommendations

• Monitor HTTP access logs for requests to /ajax.php?action=login with suspicious parameter values
• Set up alerts for database errors or unexpected query execution patterns
• Track authentication events for anomalies such as successful logins following multiple failed attempts with SQL-like patterns
• Implement real-time log analysis to correlate web server and database activity for signs of SQL injection exploitation

How to Mitigate CVE-2025-9744

Immediate Actions Required

• Restrict network access to the affected Campcodes Online Loan Management System to trusted IP addresses only
• Implement a web application firewall (WAF) with SQL injection protection rules in front of the application
• Review and audit database user privileges to ensure the application uses least-privilege accounts
• Enable detailed logging and monitoring on the affected endpoint to detect exploitation attempts

Patch Information

At the time of publication, no official patch has been released by the vendor for this vulnerability. Organizations should contact Campcodes directly for information about security updates. Monitor the VulDB entry and vendor communications for patch availability.

Workarounds

• Implement input validation to reject usernames containing SQL metacharacters such as single quotes, semicolons, and comment sequences
• Deploy a reverse proxy or WAF configured to sanitize or block SQL injection patterns in login requests
• If source code access is available, modify the login function to use parameterized queries or prepared statements
• Consider temporarily disabling remote access to the application until a proper fix is implemented
• Isolate the database server from direct network access and ensure it only accepts connections from the application server
