Plone < 3.0.0 Multiple Vulnerabilities

critical Nessus Plugin ID 328998

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of Plone installed on the remote host is prior to 3.0.0. It is, therefore, affected by the following vulnerabilities:

- Plone places a base64 encoded form of the username and password in the __ac cookie for the admin account, which makes it easier for remote attackers to obtain administrative privileges by sniffing the network.
(CVE-2008-1393)

- Plone CMS before 3 places a base64 encoded form of the username and password in the __ac cookie for all user accounts, which makes it easier for remote attackers to obtain access by sniffing the network.
(CVE-2008-1394)

- Plone CMS does not record users' authentication states, and implements the logout feature solely on the client side, which makes it easier for context-dependent attackers to reuse a logged-out session.
(CVE-2008-1395)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Plone version 3.0.0 or later.
