NVD Description

Note: Versions mentioned in the description apply only to the upstream conga package and not the conga package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.)
