Digital Creations Zope 2.3.1 b1 and earlier allows a local attacker (Zope user) with through-the-web scripting capabilities to alter ZClasses class attributes.

Digital Creations Zope 2.3.2 and earlier allows a local attacker to gain additional privileges via the changing of ZClass permission mappings for objects and methods in the ZClass.

Zope before 2.2.4 does not properly compute local roles, which could allow users to bypass specified access restrictions and gain privileges.

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.

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 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.

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.
