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 vulnerability was detected in Campcodes Online Learning Management System 1.0. This affects an unknown part of the file /admin/calendar_of_events.php. The manipulation of the argument date_start results in sql injection. The attack may be launched remotely. The exploit is now public 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 · moderate confidence

SQL injection vulnerability in Campcodes Online Learning Management System 1.0 allows remote attackers to inject malicious SQL queries via the date_start parameter in /admin/calendar_of_events.php. With CVSS 9.8, this critical flaw can lead to complete database compromise, including unauthorized data access, modification, or deletion.

MitigationImplement parameterized queries (prepared statements) for all database operations in calendar_of_events.php and ensure proper input validation on the date_start parameter. Verify authentication and authorization controls are properly enforced on the affected endpoint.

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 the installed version of Campcodes Online Learning Management System
    Check the application source code, version file, or admin panel for the version number. Look for version identifiers in footer, about page, or configuration files.
    Affected if The version is exactly 1.0 (any installation of this specific version is affected)
  2. Locate the calendar_of_events.php file
    Check if the file /admin/calendar_of_events.php exists in the web root or admin directory of the application installation.
    Affected if The file exists and is accessible on the server
  3. Verify admin endpoint accessibility
    Attempt to access the /admin/ directory or calendar_of_events.php directly via HTTP to determine if the endpoint is reachable without authentication.
    Affected if The endpoint is accessible without valid authentication credentials
  4. Inspect the date_start parameter handling
    Review the source code of calendar_of_events.php to confirm it processes a date_start parameter and uses it in SQL queries without prepared statements or input sanitization.
    Affected if The code directly incorporates the date_start parameter into SQL queries without parameter binding
  5. Check application logs for suspicious date_start values
    Review web server access logs and application logs for unusual patterns in the date_start parameter that may indicate exploitation attempts.
    Affected if Unusual or malformed values appear in date_start parameter logs, suggesting injection attempts

The environment is affected if running Campcodes Online Learning Management System version 1.0 with the /admin/calendar_of_events.php file accessible and processing the date_start parameter without SQL parameterization.
