{"id":"GHSA-8rf6-w2mx-4xjh","summary":"Undirectional routing wasn't respected in some cases in Mitogen","details":"core.py in Mitogen before 0.2.8 has a typo that drops the unidirectional-routing protection mechanism in the case of a child that is initiated by another child. The Ansible extension is unaffected. NOTE: the vendor disputes this issue because it is exploitable only in conjunction with hypothetical other factors, i.e., an affected use case within a library caller, and a bug in the message receiver policy code that led to reliance on this extra protection mechanism.","aliases":["CVE-2019-15149","PYSEC-2019-104"],"modified":"2024-12-05T05:43:17.398833Z","published":"2019-08-19T23:45:47Z","withdrawn":"2019-08-20T14:13:17Z","database_specific":{"nvd_published_at":"2019-08-18T20:15:00Z","cwe_ids":[],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2019-08-19T23:45:21Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-15149"},{"type":"WEB","url":"https://github.com/dw/mitogen/commit/5924af1566763e48c42028399ea0cd95c457b3dc"},{"type":"PACKAGE","url":"https://github.com/dw/mitogen"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/mitogen/PYSEC-2019-104.yaml"},{"type":"WEB","url":"https://mitogen.networkgenomics.com/changelog.html#v0-2-8-2019-08-18"}],"affected":[{"package":{"name":"mitogen","ecosystem":"PyPI","purl":"pkg:pypi/mitogen"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.2.8"}]}],"versions":["0.2.0","0.2.1","0.2.2","0.2.3","0.2.4","0.2.5","0.2.6","0.2.7"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/08/GHSA-8rf6-w2mx-4xjh/GHSA-8rf6-w2mx-4xjh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
