Synopsis

A web application running on the remote server is affected by multiple vulnerabilities.

Description

The version of Mattermost Server running on the remote host is prior to 7.8.12, 8.0.x prior to 8.0.3, 8.1.x prior to 8.1.3 or 9.0.0. It is, therefore, affected by multiple vulnerabilities:

 - Mattermost fails to properly validate requests to the Calls plugin, allowing an attacker sending a request without a User Agent header to cause a panic and crash the Calls plugin (CVE-2023-5967)

 - Mattermost fails to properly sanitize the user object when updating the username, resulting in the password hash being included in the response body. (CVE-2023-5968)

 - Mattermost fails to properly sanitize the request to /api/v4/redirect_location allowing an attacker, sending a specially crafted request to /api/v4/redirect_location, to fill up the memory due to caching large items. (CVE-2023-5969)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Mattermost Server version 7.8.12, 8.0.4, 8.1.3, 9.0.1 or later.
