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 reflected cross-site scripting (XSS) vulnerability exists in diskover-community <= 2.3.5 in public/selectindices.php via the namecontains parameter

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 reflected cross-site scripting (XSS) vulnerability exists in diskover-community versions 2.3.5 and earlier. The vulnerability is located in public/selectindices.php via the namecontains parameter, which does not properly sanitize user-supplied input before reflecting it back in the HTTP response, allowing attackers to inject malicious JavaScript code.

MitigationImplement proper input validation and output encoding on the namecontains parameter in selectindices.php. Sanitize or escape special characters (<, >, ", ', script tags) before reflecting user input in the response.

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 diskover-community is installed
    Locate the diskover installation directory on the system; common paths include /var/www/html/diskover, /opt/diskover, or the web server document root. Look for the main index.php or diskover-web.php files.
    Affected if The application files are present on the system.
  2. Identify the installed version
    Check the version file in the diskover installation directory, typically named VERSION, version.php, or consult the composer.json file. Alternatively, access the web interface and check any About or System Info page.
    Affected if The installed version is 2.3.5 or earlier.
  3. Verify the vulnerable script exists
    Check if public/selectindices.php exists in the diskover installation directory. This file handles the selectindices functionality and contains the namecontains parameter handler.
    Affected if The file public/selectindices.php exists and is accessible via the web server.
  4. Confirm web access is enabled
    Verify that the web server (Apache, Nginx, or built-in PHP server) is running and the diskover public directory is accessible via HTTP/HTTPS. The XSS flaw requires the web interface to be reachable.
    Affected if The application web interface is accessible and the selectindices.php endpoint responds to requests.
  5. Test for parameter reflection without sanitization
    Send a request to public/selectindices.php with a test payload in the namecontains parameter, such as namecontains=test. Examine the HTTP response to see if the input is reflected back without encoding or sanitization.
    Affected if The namecontains parameter value is reflected in the response without HTML encoding or sanitization applied.

The environment is affected if diskover-community version 2.3.5 or earlier is installed, the public/selectindices.php file exists, and the namecontains parameter reflects user input without sanitization.
