CVSS: 8.7EPSS: 0%CPEs: 2EXPL: 0CVE-2024-51734 – User data deletion by anoynmous users in Zope
https://notcve.org/view.php?id=CVE-2024-51734
04 Nov 2024 — Zope AccessControl provides a general security framework for use in Zope. In affected versions anonymous users can delete the user data maintained by an `AccessControl.userfolder.UserFolder` which may prevent any privileged access. This problem has been fixed in version 7.2. Users are advised to upgrade. Users unable to upgrade may address the issue by adding `data__roles__ = ()` to `AccessControl.userfolder.UserFolder`. • https://github.com/zopefoundation/AccessControl/issues/159 • CWE-284: Improper Access Control •
CVSS: 7.7EPSS: 0%CPEs: 5EXPL: 0CVE-2023-41050 – Information disclosure through Python's "format" functionality in Zope AccessControl
https://notcve.org/view.php?id=CVE-2023-41050
06 Sep 2023 — AccessControl provides a general security framework for use in Zope. Python's "format" functionality allows someone controlling the format string to "read" objects accessible (recursively) via attribute access and subscription from accessible objects. Those attribute accesses and subscriptions use Python's full blown `getattr` and `getitem`, not the policy restricted `AccessControl` variants `_getattr_` and `_getitem_`. This can lead to critical information disclosure. `AccessControl` already provides a saf... • https://github.com/zopefoundation/AccessControl/commit/6bc32692e0d4b8d5cf64eae3d19de987c7375bc9 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2021-32811
02 Aug 2021 — 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... • https://github.com/zopefoundation/AccessControl/security/advisories/GHSA-qcx9-j53g-ccgf • CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
CVSS: 7.2EPSS: 1%CPEs: 2EXPL: 0CVE-2021-32807 – Remote Code Execution via unsafe classes in otherwise permitted modules
https://notcve.org/view.php?id=CVE-2021-32807
30 Jul 2021 — 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 ... • https://github.com/zopefoundation/AccessControl/blob/master/CHANGES.rst#51-2021-07-30 • CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
