{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/275891?format=json","vulnerability_id":"VCID-k5mf-hy2q-k7fd","summary":"The module `AccessControl` defines security policies for Python code used in restricted code within Zope applications. 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.","aliases":[{"alias":"PYSEC-2021-367"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/22008?format=json","purl":"pkg:pypi/zope@4.3","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@4.3"},{"url":"http://public2.vulnerablecode.io/api/packages/22025?format=json","purl":"pkg:pypi/zope@5.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@5.2"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/22001?format=json","purl":"pkg:pypi/zope@4.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-k5mf-hy2q-k7fd"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@4.0"},{"url":"http://public2.vulnerablecode.io/api/packages/22002?format=json","purl":"pkg:pypi/zope@4.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-k5mf-hy2q-k7fd"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@4.1"},{"url":"http://public2.vulnerablecode.io/api/packages/22003?format=json","purl":"pkg:pypi/zope@4.1.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-k5mf-hy2q-k7fd"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@4.1.1"},{"url":"http://public2.vulnerablecode.io/api/packages/22004?format=json","purl":"pkg:pypi/zope@4.1.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-k5mf-hy2q-k7fd"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@4.1.2"},{"url":"http://public2.vulnerablecode.io/api/packages/22005?format=json","purl":"pkg:pypi/zope@4.1.3","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-k5mf-hy2q-k7fd"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@4.1.3"},{"url":"http://public2.vulnerablecode.io/api/packages/22006?format=json","purl":"pkg:pypi/zope@4.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-k5mf-hy2q-k7fd"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@4.2"},{"url":"http://public2.vulnerablecode.io/api/packages/22007?format=json","purl":"pkg:pypi/zope@4.2.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-k5mf-hy2q-k7fd"},{"vulnerability":"VCID-nrjx-fzm6-k7eb"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/zope@4.2.1"},{"url":"http://public2.vulnerablecode.io/api/packages/22020?format=json","purl":"pkg:pypi/zope@5.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1f3t-a46p-13ca"},{"vulnerability":"VCID-1psc-rasd-h7hr"},{"vulnerability":"VCID-cmb8-g5ft-bbby"},{"vulnerability":"VCID-f1nm-2rc7-eqee"},{"vulnerability":"VCID-g2d1-tcse-cyfb"},{"vulnerability":"VCID-k5mf
