Summary

Cross-site Scripting and Open Redirect in Products.ATContentTypes

Details

Impact

Plone is vulnerable to reflected cross site scripting and open redirect when an attacker can get a compromised version of the imageviewfullscreen page in a cache, for example in Varnish. The technique is known as cache poisoning. Any later visitor can get redirected when clicking on a link on this page. Usually only anonymous users are affected, but this depends on your cache settings.

Patches

A new version 3.0.6 of Products.ATContentTypes has been released with a fix. This version works on Plone 5.2 (Python 2 only) and will be included in Plone 5.2.7.

Note that the Products.CMFPlone package has the same problem in the 4.3 series. plone.app.contenttypes has the same problem in all versions, see advisory. For all unpatched versions of the three packages, you can use the following workaround.

Workaround

Make sure the imageviewfullscreen page is not stored in the cache. In Plone:

Login as Manager and go to Site Setup.
Go to the 'Caching' control panel. If this does not exist, or 'Enable caching' is not checked, you should normally not be vulnerable.
Click on the tab 'Caching operations'.
Under 'Legacy template mappings' locate the ruleset 'Content item view'.
From the last column ('Templates') remove 'imageviewfullscreen'.
Click on Save.
