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.
