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 identified in EasyCMS up to 1.6. This vulnerability affects unknown code of the file /UserAction.class.php. Such manipulation of the argument _order leads to sql injection. The attack can be executed remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

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 EasyCMS up to version 1.6 in the UserAction.class.php file via the _order parameter. The vulnerability allows remote attackers to manipulate SQL queries through unsanitized input.

MitigationReplace dynamic SQL queries with parameterized statements/prepared statements and implement proper input validation on the _order parameter to prevent SQL injection attacks.

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 EasyCMS is installed
    Look for EasyCMS installation directories or check web application inventory. Common paths include /admin, /cms, /easycms, or check for 'EasyCMS' string in application banner
    Affected if EasyCMS is present on the server
  2. Determine installed EasyCMS version
    Check version file in EasyCMS installation directory, typically version.php, about.php, or check meta tags/footer for version display
    Affected if Version is 1.6 or lower (any version up to and including 1.6)
  3. Locate UserAction.class.php file
    Search for UserAction.class.php in the application source code, typically in /include, /class, or /action directories
    Affected if UserAction.class.php file exists in the installation
  4. Verify _order parameter usage in UserAction.class.php
    Open UserAction.class.php and search for occurrences of _order parameter. Check if this parameter is used in SQL queries without proper sanitization or parameterization
    Affected if _order parameter is used in dynamic SQL queries without prepared statements or input validation
  5. Confirm remote access to vulnerable endpoint
    Test if the UserAction endpoint accepting _order parameter is accessible via HTTP requests without authentication requirements
    Affected if The vulnerable parameter can be reached remotely

A user is affected if EasyCMS version 1.6 or lower is installed and the UserAction.class.php file processes the _order parameter in SQL queries without sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 1.6
Interim mitigation

Replace dynamic SQL queries with parameterized statements/prepared statements and implement proper input validation on the _order parameter to prevent SQL injection attacks.

Recommended fix Moderate confidence
  1. Disable the affected EasyCMS application immediately if possible, or place it behind a web application firewall (WAF) to mitigate SQL injection attacks.
  2. If the application is still needed, review the /UserAction.class.php file and implement input validation/sanitization on the _order parameter to prevent SQL injection.
  3. Consider migrating to an actively maintained CMS solution as EasyCMS appears abandoned (vendor did not respond to disclosure).
  4. Monitor for any security updates from the original vendor.
Caveat No official upgrade path available; EasyCMS vendor did not respond to the disclosure and no fixed version was released.
