A vulnerability classified as critical has been found in Plone up to 2.5-5.1rc1 (Content Management System). This affects some unknown processing of the component Login Form Handler. The manipulation of the argument came_from as part of a Parameter leads to a redirect vulnerability. CWE is classifying the issue as CWE-601. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

When you visit a page where you need to login, Plone 2.5-5.1rc1 sends you to the login form with a 'came_from' parameter set to the previous url. After you login, you get redirected to the page you tried to view before. An attacker might try to abuse this by letting you click on a specially crafted link. You would login, and get redirected to the site of the attacker, letting you think that you are still on the original Plone site. Or some javascript of the attacker could be executed. Most of these types of attacks are already blocked by Plone, using the `isURLInPortal` check to make sure we only redirect to a page on the same Plone site. But a few more ways of tricking Plone into accepting a malicious link were discovered, and fixed with this hotfix.

The bug was discovered 11/28/2017. The weakness was published 01/03/2018 (Website). The advisory is shared at plone.org. This vulnerability is uniquely identified as CVE-2017-1000481 since 01/03/2018. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 36 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 2.5-5.1rc1 eliminates this vulnerability.
