URL Redirection to Untrusted Site ('Open Redirect') in Products.isurlinportal
Impact
Various parts of Plone use the 'is url in portal' check for security, mostly to see if it is safe to redirect to a url. A url like https://example.org
is not in the portal.
But the url https:example.org
without slashes tricks our code and it is considered to be in the portal.
When redirecting, some browsers go to https://example.org
, others give an error.
Attackers may use this to redirect you to their site, especially as part of a phishing attack.
Patches
The problem has been patched in Products.isurlinportal
1.2.0.
This is a recommended upgrade for all users of Plone 4.3 and 5, on Python 2.7 or higher.
It has not been tested on earlier Plone or Python versions.
Upcoming Plone 5.2.5 and higher will include the new version.
Discovered
This vulnerability was discovered and reported by Yuji Tounai of Mitsui Bussan Secure Directions, Inc. Thank you!
