CVE-2025-9505: Campcodes Loan Management System SQL Injection

CVE-2025-9505 Overview

A SQL injection vulnerability has been identified in Campcodes Online Loan Management System version 1.0. The flaw exists in the file /ajax.php?action=save_loan_type, where improper handling of the ID parameter allows attackers to inject malicious SQL commands. This vulnerability can be exploited remotely without authentication, potentially compromising the confidentiality, integrity, and availability of the underlying database and sensitive financial data managed by the application.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive loan data, modify financial records, or potentially gain unauthorized access to the underlying database server without requiring authentication.

Affected Products

• Campcodes Online Loan Management System 1.0

Technical Details for CVE-2025-9505

Vulnerability Analysis

This SQL injection vulnerability affects the loan type management functionality within Campcodes Online Loan Management System. The vulnerable endpoint /ajax.php?action=save_loan_type processes user-supplied input through the ID parameter without proper sanitization or parameterized queries. When the application constructs SQL queries using this tainted input, attackers can manipulate the query logic to perform unauthorized database operations.

The network-accessible nature of this vulnerability means that any remote attacker can craft malicious requests to exploit this flaw. The lack of authentication requirements for the vulnerable endpoint significantly increases the risk, as exploitation does not require any credentials or prior access to the system.

Root Cause

The root cause of CVE-2025-9505 is insufficient input validation and the absence of parameterized queries (prepared statements) when handling the ID parameter in the save_loan_type action. The application directly concatenates user-supplied input into SQL query strings, enabling injection attacks classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Attack Vector

The attack vector is network-based, requiring no authentication and involving low complexity. An attacker can exploit this vulnerability by sending specially crafted HTTP requests to the vulnerable endpoint with malicious SQL syntax embedded in the ID parameter. The injected SQL commands are then executed by the database server with the privileges of the application's database user.

Successful exploitation could allow attackers to:

• Extract sensitive financial and personal information from the loan management database
• Modify or delete loan records and user data
• Escalate privileges within the database
• Potentially achieve command execution on the database server depending on configuration

The exploit for this vulnerability has been publicly disclosed, as documented in the GitHub CVE Issue Discussion and VulDB entry #321488.

Detection Methods for CVE-2025-9505

Indicators of Compromise

• Unusual HTTP requests to /ajax.php?action=save_loan_type containing SQL keywords such as UNION, SELECT, DROP, INSERT, or comment sequences (--, /*)
• Database error messages or unusual query execution patterns in application logs
• Unexpected database queries originating from the web application user account
• Evidence of data exfiltration or unauthorized modifications to loan records

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the ID parameter
• Enable detailed logging for the /ajax.php endpoint and monitor for anomalous request patterns
• Deploy database activity monitoring to detect unusual queries, excessive data access, or unauthorized schema modifications
• Configure intrusion detection systems (IDS) to alert on SQL injection attack signatures

Monitoring Recommendations

• Review web server access logs for requests containing SQL injection payloads directed at the vulnerable endpoint
• Monitor database audit logs for failed login attempts, privilege escalation, or bulk data access operations
• Establish baseline behavior for the loan management application and alert on deviations from normal query patterns
• Implement real-time alerting for any database errors or exceptions generated by the application

How to Mitigate CVE-2025-9505

Immediate Actions Required

• Restrict network access to the Campcodes Online Loan Management System to trusted IP addresses only until a patch is available
• Deploy web application firewall rules to block SQL injection attempts targeting /ajax.php?action=save_loan_type
• Review database user privileges for the application and apply the principle of least privilege
• Audit the database for signs of compromise or unauthorized data access
• Consider taking the affected application offline if it processes sensitive financial data and no workaround is feasible

Patch Information

At the time of this publication, no official patch from Campcodes has been identified in the available vulnerability data. Organizations should monitor the CampCodes website for security updates and patch announcements. Given the public disclosure of exploitation details, upgrading or implementing compensating controls is strongly recommended.

For additional technical details and vulnerability tracking information, refer to the VulDB CTI entry.

Workarounds

• Implement input validation on the server-side to sanitize the ID parameter, rejecting any non-numeric characters
• Modify the application code to use parameterized queries or prepared statements instead of string concatenation for SQL query construction
• Deploy a reverse proxy or WAF in front of the application with SQL injection protection rules enabled
• Disable or restrict access to the /ajax.php?action=save_loan_type endpoint if the loan type functionality is not critical to operations

# Example: Apache mod_security rule to block SQL injection on vulnerable endpoint
SecRule REQUEST_URI "@contains /ajax.php" \
    "id:1001,\
    phase:2,\
    deny,\
    status:403,\
    chain,\
    msg:'Potential SQL Injection in Loan Management System'"
    SecRule ARGS:ID "@detectSQLi" \
        "log,\
        auditlog"
