## What is CVE-2023-25171?

CVE-2023-25171 is a high-severity denial of service vulnerability in kiwitcms kiwi, published on 15 Feb 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling)
