Restricted code is any code that resides in Zope's object database, such as the contents of `Script (Python)` objects. The policies defined in `AccessControl` severely restrict access to Python modules and only exempt a few that are deemed safe, such as Python's `string` module. However, full access to the `string` module also allows access to the class `Formatter`, which can be overridden and extended within `Script (Python)` in a way that provides access to other unsafe Python libraries. Those unsafe Python libraries can be used for remote code execution. By default, you need to 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 - which would be a very unusual configuration to begin with - are at risk. The problem has been fixed in AccessControl 4.3 and 5.2. Only AccessControl versions 4 and 5 are vulnerable, and only on Python 3, not Python 2.7. 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.","references":[{"reference_url":"https://github.com/zopefoundation/AccessControl/blob/master/CHANGES.rst#51-2021-07-30","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/zopefoundation/AccessControl/blob/master/CHANGES.rst#51-2021-07-30"},{"reference_url":"https://github.com/zopefoundation/AccessControl/commit/b42dd4badf803bb9fb71ac34cd9cb0c249262f2c","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/zopefoundation/AccessControl/commit/b42dd4badf803bb9fb71ac34cd9cb0c249262f2c"},{"reference_url":"https://github.com/zopefoundation/AccessControl/security/advisories/GHSA-qcx9-j53g-ccgf","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/zopefoundation/AccessControl/security/advisories/GHSA-qcx9-j53g-ccgf"},{"reference_url":"https://github.com/zopefoundation/Zope/commit/f72a18dda8e9bf2aedb46168761668464a4be988","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/zopefoundation/Zope/commit/f72a18dda8e9bf2aedb46168761668464a4be988"},{"reference_url":"https://github.com/zopefoundation/Zope/security/advisories/GHSA-g4gq-j4p2-j8fr","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/zopefoundation/Zope/security/advisories/GHSA-g4gq-j4p2-j8fr"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2021-32807","reference_id":"CVE-2021-32807","reference_type":"","scores":[],"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-32807"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2021-32811","reference_id":"CVE-2021-32811","reference_type":"","scores":[],"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-32811"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/22888?format=json","purl":"pkg:pypi/accesscontrol@4.3","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/accesscontrol@4.3"},{"url":"http://public2.vulnerablecode.io/api/packages/22889?format=json","purl":"pkg:pypi/accesscontrol@5.2","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/accesscontrol@5.2"}],"aliases":["CVE-2021-32807","CVE-2021-32811","GHSA-g4gq-j4p2-j8fr","GHSA-qcx9-j53g-ccgf","PYSEC-2021-335","PYSEC-2021-368","PYSEC-2021-370","PYSEC-2021-875"],"risk_score":null,"exploitability":null,"weighted_severity":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-1psc-rasd-h7hr"}],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/accesscontrol@4.3"}
