CVE-2025-10109 Overview
A SQL injection vulnerability has been identified in Campcodes Online Loan Management System version 1.0. This vulnerability affects the /ajax.php?action=delete_payment endpoint, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. The attack can be executed remotely without authentication, potentially compromising the confidentiality, integrity, and availability of the database and underlying system.
Critical Impact
Unauthenticated remote attackers can exploit this SQL injection flaw to extract sensitive financial and personal data from the loan management database, modify or delete records, or potentially escalate to further system compromise.

Technical Details for CVE-2025-10109
Vulnerability Analysis
This vulnerability is a classic SQL injection flaw (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) present in the payment deletion functionality of the Campcodes Online Loan Management System. The application fails to properly sanitize user-supplied input in the ID parameter before incorporating it into SQL queries.
The vulnerable endpoint /ajax.php?action=delete_payment accepts the ID parameter directly from user input and appears to construct SQL queries without proper parameterization or input validation. This allows attackers to manipulate the query logic by injecting SQL syntax, potentially bypassing intended restrictions and directly interacting with the backend database.
Financial applications like loan management systems typically store sensitive information including personal identification details, financial records, payment histories, and potentially banking information. Successful exploitation could lead to unauthorized data access, data manipulation, or complete database compromise.
Root Cause
The root cause of this vulnerability is the lack of proper input validation and parameterized queries when handling the ID parameter in the delete_payment action. The application directly concatenates user-controlled input into SQL statements, violating secure coding practices for database interactions.
Attack Vector
The vulnerability is exploitable remotely over the network. An attacker can craft malicious HTTP requests to the /ajax.php?action=delete_payment endpoint with specially crafted SQL payloads in the ID parameter. Since no authentication appears to be required for this endpoint, unauthenticated attackers can exploit this vulnerability.
The attack flow typically involves:
- Identifying the vulnerable endpoint and parameter
- Crafting SQL injection payloads to probe the database structure
- Extracting data using UNION-based, error-based, or blind SQL injection techniques
- Potentially modifying or deleting records, or escalating privileges within the database
Technical details and proof-of-concept information have been publicly documented. See the GitHub Issue CVE-5 for additional technical information.
Detection Methods for CVE-2025-10109
Indicators of Compromise
- Unusual or malformed requests to /ajax.php?action=delete_payment containing SQL syntax characters such as single quotes, double dashes, or UNION statements
- Database error messages appearing in application logs or HTTP responses
- Unexpected database queries or query execution times indicating blind SQL injection attempts
- Unauthorized access patterns or data exfiltration from the loan management database
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the ID parameter
- Configure intrusion detection systems (IDS) to alert on requests containing common SQL injection signatures
- Monitor application and database logs for anomalous query patterns or errors related to the ajax.php endpoint
- Deploy SentinelOne Singularity to detect and respond to exploitation attempts and post-exploitation activities
Monitoring Recommendations
- Enable detailed logging for all requests to /ajax.php endpoints with parameter values
- Configure database activity monitoring to alert on unusual queries or data access patterns
- Set up real-time alerts for SQL error messages in application logs
- Monitor for bulk data access or extraction attempts from sensitive tables
How to Mitigate CVE-2025-10109
Immediate Actions Required
- Restrict access to the Campcodes Online Loan Management System to trusted networks only until a patch is available
- Implement WAF rules to block requests containing SQL injection patterns in the ID parameter
- Consider disabling the delete_payment functionality if not immediately required
- Review and audit database access logs for signs of prior exploitation
Patch Information
At the time of publication, no official patch has been released by Campcodes for this vulnerability. Organizations should monitor the CampCodes website for security updates and patch releases. Additional vulnerability tracking information is available at VulDB #323075.
Workarounds
- Implement input validation to ensure the ID parameter only accepts numeric values
- Deploy a Web Application Firewall with SQL injection protection rules
- Apply network segmentation to limit access to the loan management system
- Use prepared statements or parameterized queries if modifying the application code is possible
- Consider temporarily taking the application offline if sensitive data is at risk
