{"id":"CVE-2021-32811","details":"Zope is an open-source web application server. Zope versions prior to versions 4.6.3 and 5.3 have a remote code execution security issue. In order to be affected, one must use Python 3 for one's Zope deployment, run Zope 4 below version 4.6.3 or Zope 5 below version 5.3, and have the optional `Products.PythonScripts` add-on package installed. By default, one must have the admin-level Zope \"Manager\" role to add or edit Script (Python) objects through the web. Only sites that allow untrusted users to add/edit these scripts through the web are at risk. Zope releases 4.6.3 and 5.3 are not vulnerable. As a workaround, a site administrator can restrict adding/editing Script (Python) objects through the web using the standard Zope user/role permission mechanisms. Untrusted users should not be assigned the Zope Manager role and adding/editing these scripts through the web should be restricted to trusted users only. This is the default configuration in Zope.","aliases":["CVE-2021-32807","GHSA-g4gq-j4p2-j8fr","GHSA-qcx9-j53g-ccgf","PYSEC-2021-335","PYSEC-2021-368","PYSEC-2021-370","PYSEC-2021-875"],"modified":"2026-05-28T04:06:45.682157348Z","published":"2021-08-02T22:15:08.333Z","related":["GHSA-g4gq-j4p2-j8fr","GHSA-qcx9-j53g-ccgf"],"database_specific":{},"references":[{"type":"ADVISORY","url":"https://github.com/zopefoundation/AccessControl/security/advisories/GHSA-qcx9-j53g-ccgf"},{"type":"ADVISORY","url":"https://github.com/zopefoundation/Zope/security/advisories/GHSA-g4gq-j4p2-j8fr"},{"type":"FIX","url":"https://github.com/zopefoundation/Zope/commit/f72a18dda8e9bf2aedb46168761668464a4be988"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zopefoundation/accesscontrol","events":[{"introduced":"4acebba0ffe57e020c847acd84eed276dd9e1696"},{"fixed":"f11416f52e5a09a521312ea20e78bbb17c7bf647"},{"introduced":"b0123dcf9ed672444ef2b53802df2f48602fe60b"},{"fixed":"e4fa02fd6f624283ec586d15d25230fc241d361d"}],"database_specific":{"cpe":"cpe:2.3:a:zope:accesscontrol:*:*:*:*:*:*:*:*","source":"CPE_RANGE","extracted_events":[{"introduced":"4.0"},{"fixed":"4.3"},{"introduced":"5.0"},{"fixed":"5.2"}]}}],"versions":["5.1","5.0","4.2","4.1","4.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-32811.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/zopefoundation/zope","events":[{"introduced":"3a49c35fc8fc697bf0db747191ac4d9e737b9ccd"},{"fixed":"67c557a8805e682192ea421848962385ae169e6c"},{"introduced":"63f7ed59b82e973b6a44cb755837df7f787ff72b"},{"fixed":"4e17a29856f80c82fdee61eadfda1b42fac92ffe"},{"fixed":"f72a18dda8e9bf2aedb46168761668464a4be988"}],"database_specific":{"extracted_events":[{"introduced":"4.0"},{"fixed":"4.6.3"},{"introduced":"5.0"},{"fixed":"5.3"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:zope:zope:*:*:*:*:*:*:*:*"}}],"versions":["4.6.2","4.6.1","5.2.1","4.6","5.2","5.1.2","4.5.5","5.1.1","4.5.4","4.5.3","5.1","4.5.2","5.0","4.5.1","4.5","4.4.4","4.4.3","4.4.2","4.4.1","4.4","4.3","4.2.1","4.2","4.1.3","4.1.2","4.1.1","4.1","4.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-32811.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
