CVE-2023-25171: Kiwitcms Kiwi Tcms

Medium severity, CVSS 5.9. EPSS: 0.9% chance of exploitation in the next 30 days.

Kiwi TCMS, an open source test management system, does not impose rate limits in versions prior to 12.0. This 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. Users should upgrade to v12.0 or later to receive a patch. As potential workarounds, users may install and configure a rate-limiting proxy in front of Kiwi TCMS and/or configure rate limits on their email server when possible.

Affected products

• Kiwitcms Kiwi Tcms: before 12.0 (fixed in 12.0)
