{"id":"GHSA-f7qw-5fgj-247x","summary":"Cross-site Scripting and Open Redirect in plone.app.contenttypes","details":"### Impact\nPlone is vulnerable to reflected cross site scripting and open redirect when an attacker can get a compromised version of the image_view_fullscreen page in a cache, for example in Varnish.\nThe technique is known as cache poisoning.\nAny later visitor can get redirected when clicking on a link on this page.\nUsually only anonymous users are affected, but this depends on your cache settings.\n\n### Patches\nNew versions of plone.app.contenttypes have been released.\nVersion 2.2.3 works on Plone 5.2 and will be included in Plone 5.2.7.\nVersion 3.0.0a9 works on Plone 6 and will be included in Plone 6.0.0a3.\n\nNote that the Products.CMFPlone package has the same problem in the 4.3 series.\nIn Plone 5.0-5.2, the default Products.ATContentTypes version has the same problem. See [advisory](https://github.com/plone/Products.ATContentTypes/security/advisories/GHSA-g4c2-ghfg-g5rh).\nFor all unpatched versions of the three packages, you can use the following workaround.\n\n### Workaround\nMake sure the image_view_fullscreen page is not stored in the cache.\nIn Plone:\n\n* Login as Manager and go to Site Setup.\n* Go to the 'Caching' control panel. If this does not exist, or 'Enable caching' is not checked, you should normally not be vulnerable.\n* Click on the tab 'Caching operations'.\n* Under 'Legacy template mappings' locate the ruleset 'Content item view'.\n* From the last column ('Templates')  remove 'image_view_fullscreen'.\n* Click on Save.\n\n### Reporter\nThis vulnerability was responsibly disclosed to the Plone Security Team by Gustav Hansen, F-Secure Consulting.
