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 found in MAGESH-K21 Online-College-Event-Hall-Reservation-System 1.0. It has been rated as problematic. This issue affects some unknown processing of the file /admin/update-rooms.php. The manipulation of the argument id leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-256967. NOTE: 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 · high confidence

A reflected cross-site scripting (XSS) vulnerability exists in the /admin/update-rooms.php file of the MAGESH-K21 Online-College-Event-Hall-Reservation-System 1.0. The 'id' parameter is not properly sanitized before being included in the response, allowing an attacker to inject malicious JavaScript code that executes in the victim's browser when they interact with the crafted URL.

MitigationImplement proper input validation and output encoding for the 'id' parameter in update-rooms.php. Use context-appropriate encoding when reflecting user input back to the browser, and consider implementing Content Security Policy (CSP) headers as a defense-in-depth measure.

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 MAGESH-K21 Online College Event Hall Reservation System is installed
    Locate the application files on the server - look for directories containing 'update-rooms.php' or the application's web root
    Affected if The application is present on the server
  2. Verify the application version
    Check any version file, README, or meta information within the application installation directory
    Affected if The installed version is 1.0
  3. Confirm vulnerable file exists
    Check if /admin/update-rooms.php exists in the web root of the application
    Affected if The file /admin/update-rooms.php exists in the application directory
  4. Inspect the 'id' parameter handling in update-rooms.php
    Open /admin/update-rooms.php and locate the code that handles the 'id' parameter - check if it is directly included in the response without sanitization or encoding
    Affected if The 'id' parameter is echoed back to the user without proper input validation or output encoding

A user is affected if the MAGESH-K21 Online College Event Hall Reservation System version 1.0 is installed and the /admin/update-rooms.php file exists with the 'id' parameter being reflected without sanitization.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement proper input validation and output encoding for the 'id' parameter in update-rooms.php. Use context-appropriate encoding when reflecting user input back to the browser, and consider implementing Content Security Policy (CSP) headers as a defense-in-depth measure.

Recommended fix Low confidence
  1. 1. Locate the file /admin/update-rooms.php in the application directory
  2. 2. Find the code that handles the 'id' parameter (typically from $_GET, $_POST, or $_REQUEST)
  3. 3. Apply output encoding using htmlspecialchars() or htmlentities() when displaying the id value. For example: $id = htmlspecialchars($_GET['id'], ENT_QUOTES, 'UTF-8');
  4. 4. Additionally, implement input validation: validate that 'id' contains only expected characters (e.g., alphanumeric) using preg_match() or filter_var()
  5. 5. For stored XSS prevention, also sanitize before database storage using prepared statements
  6. 6. Add a Content-Security-Policy (CSP) header in the server configuration or PHP to restrict inline scripts: Header set Content-Security-Policy "default-src 'self'; script-src 'self'"
  7. 7. Test the fix by attempting XSS payloads in the id parameter (e.g., <script>alert('XSS')</script>)
  8. 8. Apply same sanitization to all user-supplied inputs throughout the application
