medium Nessus Plugin ID 205292

Language:

Synopsis

The remote host is missing a security update.

Description

The version of Mattermost Server installed on the remote host is prior to 9.5.7 or 9.9.1 / 9.10.0. It is, therefore, affected by a vulnerability as referenced in the MMSA-2024-00356 advisory.

 - Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6 fail to properly validate synced reactions, when shared channels are enabled, which allows a malicious remote to create arbitrary reactions on arbitrary posts (CVE-2024-29977)

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 9.5.7 / 9.9.1 / 9.10.0 or later.
