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 has been discovered in BigProf Online Invoicing System 2.6, which does not sufficiently encode user-controlled input, resulting in persistent XSS through /inventory/items_view.php, in the FirstRecord parameter. Exploitation of this vulnerability could allow an attacking user to store dangerous JavaScript payloads on the system that will be triggered when the page loads.

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

A stored XSS vulnerability in BigProf Online Invoicing System 2.6 allows attackers to inject malicious JavaScript through the FirstRecord parameter in /inventory/items_view.php. The application fails to properly sanitize or encode user input before storing and displaying it, causing the payload to persist and execute when other users view the affected page.

MitigationImplement proper input validation and context-appropriate output encoding for the FirstRecord parameter and all user-controlled inputs in items_view.php. Additionally, deploy Content Security Policy headers to mitigate XSS execution.

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 BigProf Online Invoicing System installation
    Locate the application in your web server document root. Common paths include /var/www/html/, /www/, or C:\inetpub\wwwroot\. Look for the main application directory containing files like login.php or index.php.
    Affected if The BigProf Online Invoicing System is installed and accessible on the server.
  2. Verify the affected version
    Check the application version. This is typically displayed in the footer of pages, in an About section within the admin panel, or in a version.php file if one exists. Compare the version number to the affected range.
    Affected if The installed version is exactly 2.6.
  3. Locate the vulnerable script
    Navigate to the /inventory/ subdirectory within the application root and confirm that items_view.php exists. This is the specific file that handles the FirstRecord parameter.
    Affected if The file /inventory/items_view.php exists and is accessible via the web server.
  4. Inspect the FirstRecord parameter handling
    Open items_view.php and search for code that processes the FirstRecord parameter, typically via $_GET or $_POST. Examine how this parameter value is stored and later output to users without sanitization.
    Affected if The FirstRecord parameter is processed and its value is stored/displayed without proper input validation or output encoding.
  5. Verify lack of output encoding
    Review the code around the FirstRecord parameter display. Look for absence of htmlspecialchars(), htmlentities(), or similar encoding functions when the parameter value is rendered in HTML context.
    Affected if The FirstRecord value is directly echoed or rendered in HTML without escaping or encoding.

You are affected if BigProf Online Invoicing System version 2.6 is installed and the /inventory/items_view.php file processes the FirstRecord parameter without sanitization or output encoding.
