CVE-2025-9506: Campcodes Loan Management System SQL Vuln

CVE-2025-9506 Overview

CVE-2025-9506 is a SQL Injection vulnerability affecting Campcodes Online Loan Management System version 1.0. The vulnerability exists in the /ajax.php?action=delete_plan endpoint, where improper handling of the ID parameter allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive financial and personal data from the loan management database, modify loan records, or potentially compromise the underlying database server.

Technical Details for CVE-2025-9506

Vulnerability Analysis

This SQL Injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs due to insufficient input validation in the loan plan deletion functionality. The vulnerable endpoint accepts user-supplied input through the ID parameter without proper sanitization, allowing attackers to inject arbitrary SQL statements directly into database queries.

The vulnerability is exploitable remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious requests containing SQL payloads in the ID parameter, which are then executed by the backend database. This can result in unauthorized access to confidential loan records, customer personal information, and financial data stored in the system.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and parameterized queries in the /ajax.php file when processing the delete_plan action. The application directly concatenates user-supplied input from the ID parameter into SQL queries without sanitization, creating a classic SQL injection attack surface. The absence of prepared statements or proper escaping mechanisms allows malicious SQL code to be interpreted as part of the query structure.

Attack Vector

The attack vector is network-based, requiring no authentication or privileges. An attacker can send crafted HTTP requests to the /ajax.php?action=delete_plan endpoint with malicious SQL payloads in the ID parameter. The exploit has been publicly disclosed, as documented in the GitHub CVE Issue Discussion. The attacker can leverage this vulnerability to perform various SQL injection attacks including UNION-based extraction, blind SQL injection, or time-based techniques to exfiltrate database contents.

Detection Methods for CVE-2025-9506

Indicators of Compromise

Unusual HTTP requests to /ajax.php?action=delete_plan containing SQL syntax characters such as single quotes, semicolons, or SQL keywords like UNION, SELECT, DROP
Database error messages appearing in application logs or responses indicating malformed SQL queries
Unexpected modifications to loan plan records or database tables
Anomalous database query patterns showing data extraction or enumeration behavior

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the ID parameter of requests to /ajax.php
Configure database activity monitoring to alert on suspicious query patterns, especially those involving the loan plan tables
Enable detailed logging for the /ajax.php endpoint and monitor for requests containing encoded or obfuscated SQL injection payloads
Deploy intrusion detection signatures to identify known SQL injection attack patterns targeting this specific endpoint

Monitoring Recommendations

Review web server access logs for requests to /ajax.php?action=delete_plan with unusual ID parameter values
Monitor database audit logs for failed queries or unauthorized data access attempts
Set up alerts for application errors related to SQL syntax or database connection issues
Track changes to loan plan records for unauthorized deletions or modifications

How to Mitigate CVE-2025-9506

Immediate Actions Required

Restrict access to the /ajax.php?action=delete_plan endpoint using network-level controls until a patch is available
Implement WAF rules to block requests containing SQL injection patterns in the ID parameter
Review and audit all loan plan data for signs of unauthorized access or modification
Consider temporarily disabling the delete plan functionality if not critical to operations

Patch Information

At the time of this writing, no official patch from Campcodes has been identified in the available CVE data. Organizations using the Online Loan Management System should monitor the CampCodes website and VulDB entry #321489 for security updates. Contact the vendor directly for remediation guidance.

Workarounds

Implement input validation at the application level to sanitize the ID parameter, allowing only numeric values
Deploy a reverse proxy or WAF with SQL injection detection capabilities in front of the application
Restrict network access to the affected endpoint to trusted IP addresses only
If source code access is available, modify the vulnerable code to use prepared statements with parameterized queries
