A vulnerability, which was classified as critical, was found in Plone 2.5-5.1rc1 (Content Management System). Affected is some unknown functionality of the component Login Form. The manipulation 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. CVE summarizes:

By linking to a specific url in Plone 2.5-5.1rc1 with a parameter, an attacker could send you to his own website. On its own this is not so bad: the attacker could more easily link directly to his own website instead. But in combination with another attack, you could be sent to the Plone login form and login, then get redirected to the specific url, and then get a second redirect to the attacker website. (The specific url can be seen by inspecting the hotfix code, but we don't want to make it too easy for attackers by spelling it out here.)

The bug was discovered 11/28/2017. The weakness was presented 01/03/2018 (Website). The advisory is shared for download at plone.org. This vulnerability is traded as CVE-2017-1000484 since 01/03/2018. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly 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.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
