security flaw

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.

security flaw

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.

security flaw

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.

security flaw

The DocumentTemplate package in Zope 2.2 and earlier allows a remote attacker to modify DTMLDocuments or DTMLMethods without authorization.

The DTML implementation in the Z Object Publishing Environment (Zope) allows remote attackers to conduct unauthorized activities.

User data deletion by anoynmous users in Zope

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`.

Products.SQLAlchemyDA vulnerable to unauthenticated arbitrary SQL query execution

SQLAlchemyDA is a generic database adapter for ZSQL methods. A vulnerability found in versions prior to 2.2 allows unauthenticated execution of arbitrary SQL statements on the database to which the SQLAlchemyDA instance is connected. All users are affected. The problem has been patched in version 2.2. There is no workaround for the problem.

Multiple cross-site request forgery (CSRF) vulnerabilities in Zope Management Interface 4.3.7 and earlier, and Plone before 5.x.

zope: Cross-site scripting (XSS) in ZMI pages through manage_tabs_message()

Cross-site scripting (XSS) vulnerability in ZMI pages that use the manage_tabs_message in Zope 2.11.4, 2.11.2, 2.10.9, 2.10.7, 2.10.6, 2.10.5, 2.10.4, 2.10.2, 2.10.1, 2.12.

(Plone): Reflexive HTTP header injection

ZPublisher.HTTPRequest._scrubHeader in Zope 2 before 2.13.19, as used in Plone before 4.3 beta 1, allows remote attackers to inject arbitrary HTTP headers via a linefeed (LF) character.

(Plone): Partial restricted Python sandbox escape

The App.Undo.UndoSupport.get_request_var_or_attr function in Zope before 2.12.21 and 3.13.x before 2.13.11, as used in Plone before 4.2.3 and 4.3 before beta 1, allows remote authenticated users to gain access to restricted attributes via unspecified vectors.

(Plone): Timing attack in password validation

AccessControl/AuthEncoding.py in Zope before 2.13.19, as used in Plone before 4.2.3 and 4.3 before beta 1, allows remote attackers to obtain passwords via vectors involving timing discrepancies in password validation.

(Plone): Python random generator used instead of system random generator

Zope before 2.13.19, as used in Plone before 4.2.3 and 4.3 before beta 1, does not reseed the pseudo-random number generator (PRNG), which makes it easier for remote attackers to guess the value via unspecified vectors. NOTE: this issue was SPLIT from CVE-2012-5508 due to different vulnerability types (ADT2).

zope: Unspecified vulnerability in Zope v2.12.x and Zope v2.13.x allowing arbitrary code execution

Unspecified vulnerability in Zope 2.12.x and 2.13.x, as used in Plone 4.0.x through 4.0.9, 4.1, and 4.2 through 4.2a2, allows remote attackers to execute arbitrary commands via vectors related to the p_ class in OFS/misc_.py and the use of Python modules.

plone: privilege escalation vulnerability

Unspecified vulnerability in (1) Zope 2.12.x before 2.12.19 and 2.13.x before 2.13.8, as used in Plone 4.x and other products, and (2) PloneHotfix20110720 for Plone 3.x allows attackers to gain privileges via unspecified vectors, related to a "highly serious vulnerability." NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-0720.

Race condition in ZEO/StorageServer.py in Zope Object Database (ZODB) before 3.10.0 allows remote attackers to cause a denial of service (daemon outage) by establishing and then immediately closing a TCP connection, leading to the accept function having an unexpected return value of None, an unexpected value of None for the address, or an ECONNABORTED, EAGAIN, or EWOULDBLOCK error, a related issue to CVE-2010-3492.

Zope: Zope child threads termination due unhandled exceptions in PluggableAuthService (PAS)

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.

zope: XSS on error page

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 allows remote attackers to inject arbitrary web script or HTML via vectors related to error messages.

Zope vulnerable to Stored Cross Site Scripting with SVG images

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. Patches are available in Zope 4.8.10 and 5.8.5. As a workaround, make sure the "Add Documents, Images, and Files" permission is only assigned to trusted roles. By default, only the Manager has this permission.

Zope management interface vulnerable to stored cross site scripting via the title property

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.
