{"id":"CVE-2023-25171","aliases":["GHSA-7j9h-3jxf-3vrf","PYSEC-2026-836"],"url":"https://o3.security/vulnerability/CVE-2023-25171","summary":"Kiwi TCMS has denial of service vulnerability on Password reset page","details":"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.","published":"2023-02-15T00:00:00Z","modified":"2026-07-15T01:49:08.419304490Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"kiwitcms","fixedVersion":"12.0"}],"fix":{"url":"https://github.com/kiwitcms/Kiwi/commit/761305d04f5910ba14cc04d1255a8f1afdbb87f3","label":"kiwitcms/Kiwi@761305d"},"references":[{"type":"WEB","url":"https://huntr.dev/bounties/3b712cb6-3fa3-4f71-8562-7a7016c6262e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25171.json"},{"type":"ADVISORY","url":"https://github.com/kiwitcms/Kiwi/security/advisories/GHSA-7j9h-3jxf-3vrf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-25171"},{"type":"FIX","url":"https://github.com/kiwitcms/Kiwi/commit/761305d04f5910ba14cc04d1255a8f1afdbb87f3"},{"type":"ARTICLE","url":"https://kiwitcms.org/blog/kiwi-tcms-team/2023/02/15/kiwi-tcms-120/"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:08.419304490Z"}}
