CVSS v3.1

7.5

High

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions: MobaXterm versions prior to 21.0

Description: The issue allows remote servers to cause a denial of service, resulting in a Windows GUI hang, via tab title change requests sent repeatedly at high speed. This leads to many SetWindowTextA or SetWindowTextW calls.

Recommendations: For versions prior to 21.0, update to version 21.0 or later to resolve the issue. As a temporary workaround, consider restricting the speed of tab title change requests from remote servers to minimize the risk of exploitation.
