Denial of service vulnerability on Password reset page

Critical
atodorov published GHSA-7j9h-3jxf-3vrf Feb 15, 2023

Package

Kiwi TCMS

Affected versions

<=11.7

Patched versions

12.0

Description

Impact

Previous versions of Kiwi TCMS do not impose rate limits which makes it easier to attempt denial-of-service attacks against the Password reset page. An attacker could potentially send a large number of emails if they know the email addresses of users in Kiwi TCMS. Additionally that may strain SMTP resources.

Patches

Users should upgrade to v12.0 or later.

Workarounds

Users may install and configure a rate-limiting proxy in front of Kiwi TCMS such as Nginx and/or configure rate limits on their email server when possible.
