FreeBSD : element-web -- matrix-react-sdk vulnerable to HTML injection in search results via plaintext message highlighting (c676bb1b-e3f8-11ed-b37b-901b0e9408dc)

medium Nessus Plugin ID 174766

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the c676bb1b-e3f8-11ed-b37b-901b0e9408dc advisory.

 - matrix-react-sdk is a react-based SDK for inserting a Matrix chat/VoIP client into a web page. Prior to version 3.71.0, plain text messages containing HTML tags are rendered as HTML in the search results. To exploit this, an attacker needs to trick a user into searching for a specific message containing an HTML injection payload. No cross-site scripting attack is possible due to the hardcoded content security policy. Version 3.71.0 of the SDK patches over the issue. As a workaround, restarting the client will clear the HTML injection. (CVE-2023-30609)

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

Solution

Update the affected packages.
