Zope is an open-source web application server. The title property, available on most Zope objects, can be used to store script code that is executed while viewing the affected object in the Zope Management Interface (ZMI). All versions of Zope 4 and Zope 5 are affected. Patches will be released with Zope versions 4.8.11 and 5.8.6
Zope is an open-source web application server. Prior to versions 4.8.10 and 5.8.5, there is a stored cross site scripting vulnerability for SVG images. Note that an image tag with an SVG image as source is never vulnerable, even when the SVG image contains malicious code. To exploit the vulnerability, an attacker would first need to upload an image, and then trick a user into following a specially crafted link. …
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 safe variant for str.format and denies …
ZServer in Zope 2.10.x before 2.10.12 and 2.11.x before 2.11.7 allows remote attackers to cause a denial of service (crash of worker threads) via vectors that trigger uncaught exceptions.
The DocumentTemplate package in Zope 2.2 and earlier allows a remote attacker to modify DTMLDocuments or DTMLMethods without authorization.
The "through the web code" capability for Zope 2.0 through 2.5.1 b1 allows untrusted users to shut down the Zope server via certain headers.
The DTML implementation in the Z Object Publishing Environment (Zope) allows remote attackers to conduct unauthorized activities.
Zope 2.2.0 through 2.5.1 does not properly verify the access for objects with proxy roles, which could allow some users to access documents in violation of the intended configuration.
Zope before 2.2.1 does not properly restrict access to the getRoles method, which allows users who can edit DTML to add or modify roles by modifying the roles list that is included in a request.
Zope 2.2.0 through 2.2.4 does not properly perform security registration for legacy names of object constructors such as DTML method objects, which could allow attackers to perform unauthorized activities.
Zope 2.2.0 through 2.2.4 does not properly protect a data updating method on Image and File objects, which allows attackers with DTML editing privileges to modify the raw data of these objects.
ZCatalog plug-in index support capability for Zope 2.4.0 through 2.5.1 allows anonymous users and untrusted code to bypass access restrictions and call arbitrary methods of catalog indexes.
Cross-site scripting (XSS) vulnerability in Zope 2.8.x before 2.8.12, 2.9.x before 2.9.12, 2.10.x before 2.10.11, 2.11.x before 2.11.6, and 2.12.x before 2.12.3, 3.1.1 through 3.4.1. allows remote attackers to inject arbitrary web script or HTML via vectors related to the way error messages perform sanitization. NOTE: this issue exists because of an incomplete fix for CVE-2010-1104
Zope is an open-source web application server. Zope versions have a remote code execution security issue.
Zope is an open-source web application server. This advisory extends the previous advisory at https://github.com/zopefoundation/Zope/security/advisories/GHSA-5pr9-v234-jw36. Most Python modules are not available for using in TAL expressions that you can add through-the-web, for example in Zope Page Templates. This restriction avoids file system access, for example via the os module. But some of the untrusted modules are available indirectly through Python modules that are available for direct use. By default, you …
Untrusted users should not be assigned the Zope Manager role and adding/editing Zope Page Templates through the web should be restricted to trusted users only.
Zope Products.CMFCore and Products.PluggableAuthService, as used in Plone and other products, allow Reflected XSS.
