CVE-2024-51640
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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in Matt Rude MDR Webmaster Tools mdr-webmaster-tools allows Stored XSS.This issue affects MDR Webmaster Tools: from n/a through <= 1.1.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in MDR Webmaster Tools allows authenticated users to be tricked into submitting malicious requests that persist stored XSS payloads. An attacker can craft a malicious link or form that, when triggered by an authenticated admin, injects persistent malicious scripts into the application that execute for all users viewing the affected content.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm MDR Webmaster Tools installationIdentify if MDR Webmaster Tools is present in your environment by checking installed software, application directories, or web server configurations for this specific product nameAffected if MDR Webmaster Tools is installed and accessible to users
-
Check for anti-CSRF token implementationInspect the application's HTML forms and AJAX requests for the presence of anti-CSRF tokens (typically hidden form fields or request headers with names like 'csrf_token', 'csrf', 'token', or 'XSRF-TOKEN'). Verify that these tokens are generated server-side and validated on state-changing operationsAffected if Anti-CSRF tokens are missing from state-changing forms or requests
-
Verify Origin and Referer header validationExamine server-side code or proxy configurations to confirm that Origin and/or Referer headers are validated for state-changing requests, ensuring requests originate from allowed domainsAffected if Origin/Referer header validation is not implemented or can be bypassed
-
Test for stored XSS via CSRFWith an authenticated session, attempt to submit a benign script payload (e.g., <script>alert(1)</script>) through forms or parameters that store data persistently. Then log out and view the stored content as a different user to see if the script executesAffected if Stored XSS payloads persist and execute for other users viewing the affected content
A user is affected if MDR Webmaster Tools is installed AND lacks anti-CSRF token protection on state-changing operations, allowing attackers to inject persistent XSS that executes for all users viewing the injected content.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement anti-CSRF tokens (synchronizer token pattern) on all state-changing operations and validate Origin/Referer headers. Additionally, apply proper output encoding and input validation to prevent stored XSS injection.
