high Nessus Plugin ID 379722

Synopsis

An application installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of JetBrains Toolbox App installed on the remote host is prior to 3.6.1. It is, therefore, affected by multiple vulnerabilities:

- In JetBrains Toolbox App before 3.6.1 NTLM hash disclosure was possible via SVG tool icons from a Remote Development server. (CVE-2026-123856)

- In JetBrains Toolbox App before 3.6.1 command injection was possible via enterprise configuration URLs.
(CVE-2026-123855)

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 JetBrains Toolbox App version 3.6.1 or later.
