CVE-2010-3198 Zope: Zope child threads termination due unhandled exceptions in PluggableAuthService (PAS)
Last modified: 2016-03-01 04:28:32 EST
Zope application server framework improperly handled certain exceptions
in the code of PluggableAuthService (PAS). A remote, unauthenticated
user could request / access a private page, resulting in unhandled
exception to occur and Zope thread termination. Repetition of the
attack scenario could allow an attacker to terminate all Zope child
treads, leading to denial of service.
a, against v2.10 branch:
b, against v2.11 branch:
Public proof of concept (from ):
The easiest way to trigger this behaviour, is buildout.
Create this buildout.cfg:
Get yourself a copy of bootstrap.py and run buildout.
* Start Zope
* Create a new Plone site
* Add a new page, make it private.
* Log out
* As anonymous, manually craft the following URL: http://yoursite/plone/new_page?came_from:list=123
This issue affects the version of the zope package, as present within
Not vulnerable. This issue did not affect the versions of conga as shipped with Red Hat Cluster Suite for Red Hat Enterprise Linux 4 and as shipped with Red Hat Enterprise Linux 5 as they use own internal mechanism to verify if user requesting particular page is authenticated. Plone private pages permissions configuration mechanism is not used in conga.
