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
Pegasus CMS 1.0 contains a remote code execution vulnerability in the extra_fields.php plugin that allows unauthenticated attackers to execute arbitrary commands by exploiting unsafe eval functionality. Attackers can send POST requests to the submit.php endpoint with malicious PHP code in the action parameter to achieve code execution and obtain an interactive shell.

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

Pegasus CMS 1.0 contains an unauthenticated remote code execution vulnerability in the extra_fields.php plugin. The vulnerability stems from unsafe eval functionality that processes the action parameter from POST requests to the submit.php endpoint, allowing attackers to inject and execute arbitrary PHP code.

MitigationImmediate mitigation requires disabling or restricting access to the vulnerable submit.php endpoint until a patch can be applied. The fix involves removing unsafe eval usage and implementing proper input validation/sanitization in the extra_fields.php plugin.

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. Confirm Pegasus CMS version
    Locate the CMS installation directory and identify the installed version by checking version files, headers, or the CMS admin panel for the exact version number. Compare against the affected version 1.0.
    Affected if The installed version is Wisdom Pegasus Cms 1.0
  2. Locate extra_fields.php plugin file
    Search the web root and plugin directories for a file named extra_fields.php. Common paths may include /plugins/, /includes/, or the root web directory.
    Affected if The file extra_fields.php exists in the installation
  3. Verify submit.php endpoint accessibility
    Check for the presence of submit.php in the web root or plugin directories. This endpoint accepts POST requests with the action parameter.
    Affected if submit.php is accessible via HTTP/HTTPS without authentication
  4. Inspect eval usage in extra_fields.php
    Open extra_fields.php and search for eval() function calls. Verify if user input (particularly the action parameter from POST requests) is passed directly to eval without sanitization.
    Affected if The code contains unsafe eval() that processes the action parameter without input validation

A user is affected if they are running Wisdom Pegasus Cms version 1.0 with the extra_fields.php plugin present and accessible, as this allows unauthenticated remote code execution through the submit.php endpoint.
