Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A security vulnerability has been detected in Campcodes Online Loan Management System 1.0. Affected is an unknown function of the file /ajax.php?action=save_borrower. The manipulation of the argument lastname leads to sql injection. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A critical SQL injection vulnerability exists in Campcodes Online Loan Management System 1.0. The `lastname` parameter in the `/ajax.php?action=save_borrower` endpoint fails to sanitize user input, allowing unauthenticated remote attackers to inject arbitrary SQL queries. This can lead to full database compromise, including exfiltration of sensitive borrower data and potential system takeover.

MitigationApply vendor patches immediately; if unavailable, refactor the save_borrower action to use parameterized queries/prepared statements for the lastname and all other user-supplied parameters. Restrict access to ajax.php endpoints as an interim control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Campcodes Online Loan Management System is installed
    Search your web server for files containing 'Online Loan Management System' or check for the presence of ajax.php in your web application's directory structure.
    Affected if The application is present on the server and accessible via web
  2. Verify the installed version is 1.0
    Check the application's source code for a version identifier, typically found in a README, version file, or within the main PHP files. Compare your version against the affected range (1.0).
    Affected if The installed version is exactly 1.0
  3. Confirm the ajax.php endpoint exists and is web-accessible
    Attempt to access your application's ajax.php file via HTTP/HTTPS (e.g., https://yourdomain.com/ajax.php). The CVE states this endpoint is reachable without authentication.
    Affected if The ajax.php file exists and responds to requests without requiring login credentials
  4. Verify the save_borrower action is implemented
    Examine the ajax.php source code to confirm the 'save_borrower' action handler exists and processes the lastname parameter without sanitization.
    Affected if The save_borrower case is present in ajax.php and directly uses the lastname parameter in SQL queries without prepared statements or input escaping
  5. Check if the database user has write privileges
    Review the database configuration in the application to determine if the connected database user has permissions that would allow SQL injection to exfiltrate or modify data.
    Affected if The application database user has SELECT, INSERT, or administrative privileges that could be exploited through SQL injection

Your environment is affected if you are running Campcodes Online Loan Management System version 1.0 with the ajax.php endpoint publicly accessible and the save_borrower action handling the lastname parameter without parameterized queries.
