CVE-2023-25171: Kiwi TCMS has denial of service vulnerability on Password reset page

• Severity: medium (CVSS 5.9 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.9% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2023-02-15 · updated 2026-06-17
• Weakness: CWE-770

Description

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: before 12.0 — fixed in 12.0

How to fix

Upgrade to a fixed version: kiwitcms Kiwi 12.0. Check the vendor advisory for mitigations.
