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
Evoluted PHP Directory Listing Script through 4.0.5 contains a reflected cross-site scripting vulnerability in index.php where the dir parameter value is reflected without HTML encoding inside the HTML title element and inside anchor href attributes in the breadcrumb navigation. Attackers can inject arbitrary JavaScript via crafted dir parameter values by breaking out of the title context or injecting event handlers into breadcrumb anchor attributes to execute malicious scripts in a victim's browser.

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

Evoluted PHP Directory Listing Script through 4.0.5 has a reflected XSS in index.php where the 'dir' parameter is output without HTML encoding, allowing injection into the HTML title element and breadcrumb anchor href attributes.

MitigationApply output encoding (htmlspecialchars with ENT_QUOTES) to the 'dir' parameter before rendering in the title element and anchor href attributes.

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. Locate the Evoluted PHP Directory Listing Script installation
    Search the web server for index.php that belongs to this script, typically in the document root. Look for files containing 'Evoluted' or 'Directory Listing' in comments/headers.
    Affected if The script is present on the server
  2. Identify the installed version
    Open the main index.php file and search for a version string (e.g., 'version', '4.0.5', 'v.') in the code comments or configuration section near the top of the file.
    Affected if The version is 4.0.5 or lower (any version through 4.0.5)
  3. Verify the dir parameter is processed
    Search the index.php source code for occurrences of '$_GET' or '$_REQUEST' referencing 'dir' parameter, and confirm it is used in the page output.
    Affected if The dir parameter is read from the URL and included in the page output without validation
  4. Confirm output encoding is missing
    Examine the code where the dir parameter value is output. Check if htmlspecialchars, htmlentities, or equivalent encoding is applied before rendering in the HTML title tag (<title>) and anchor href attributes in the breadcrumb section.
    Affected if The dir parameter value is output directly without htmlspecialchars or equivalent encoding
  5. Test for live XSS (optional manual check)
    If you have access, request a URL such as /index.php?dir=test"><script>alert(1)</script> and inspect the page source to see if the script tag appears unescaped in the title or anchor href.
    Affected if The injected script tags or event handlers appear literally in the HTML source

You are affected if the Evoluted PHP Directory Listing Script version 4.0.5 or lower is installed and the dir parameter is processed without HTML encoding in the page output.
