Plone < 2.5.3 XSS

medium Nessus Plugin ID 329004

Synopsis

The remote host is affected by a cross-site scripting vulnerability.

Description

The version of Plone installed on the remote host is prior to 2.5.3. It is, therefore, affected by a cross-site scripting (XSS) vulnerability, in the skins/plone_templates/default_error_message.pt due to improper validation of the type_name parameter to Members/ipa/createObject before returning it to users.. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

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 2.5.3 or later.
