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 version of Plone installed on the remote host is 2.5.5 prior to 4.3.16, 5.0.x prior to 5.0.10. It is, therefore, affected by the following vulnerabilities:

  - When you visit a page where you need to login, sends you to the login form with a 'came_from' parameter     set to the previous url. (CVE-2017-1000481)

  - A member of the Plone site could set javascript in the home_page property of his profile, and have this     executed when a visitor click the home page link on the author page. (CVE-2017-1000482)

  - Accessing private content via str.format in through-the-web templates and scripts in Plone.
    (CVE-2017-1000483)

  - By linking to a specific url in Plone with a parameter, an attacker could send you to his own website.
    (CVE-2017-1000484)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number. Since a vendor hotfix (PloneHotfix20171128) may remediate this without a version upgrade, this plugin only reports when running in Paranoid mode.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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.) (CVE-2017-1000484)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
