FreeBSD : Kanboard -- Clipboard based cross-site scripting (blocked with default CSP) in Kanboard (79514fcd-feb4-11ed-92b5-b42e991fc52e)

medium Nessus Plugin ID 176528

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 79514fcd-feb4-11ed-92b5-b42e991fc52e advisory.

 - Kanboard is project management software that focuses on the Kanban methodology. Due to improper handling of elements under the `contentEditable` element, maliciously crafted clipboard content can inject arbitrary HTML tags into the DOM. A low-privileged attacker with permission to attach a document on a vulnerable Kanboard instance can trick the victim into pasting malicious screenshot data and achieve cross-site scripting if CSP is improperly configured. This issue has been patched in version 1.2.29.
 (CVE-2023-32685)

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.
