Plone < 2.5.5 / 3.x < 3.3.6 / 4.x < 4.0.4 Privilege Escalation (HF 20110720)

critical Nessus Plugin ID 329012

Synopsis

The remote host is affected by a privilege escalation vulnerability.

Description

The version of Plone installed on the remote host is prior to 2.5.5, 3.x prior to 3.3.6, or 4.x prior to 4.0.4. It is, therefore, affected by a privilege escalation vulnerability. An unauthenticated, remote attacker can exploit this to gain administrative access to the application.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number. Since a vendor hotfix (PloneHotfix20110720) may remediate this without a version upgrade, this plugin only reports when running in Paranoid mode.

Solution

Apply the vendor hotfix (Products.PloneHotfix20110720), or upgrade to Plone 2.5.5, 3.3.6, 4.0.4 or later.
