Plone 2.5.x < 2.5.5 / 3.x < 3.3.6 / 4.x < 4.0.4 / 4.1.x < 4.1.1 Multiple Vulnerabilities (HF 20110531)

medium Nessus Plugin ID 329001

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of Plone installed on the remote host is 2.5.x prior to 2.5.5, 3.x prior to 3.3.6, 4.x prior to 4.0.4, 4.1.x prior to 4.1.1. It is, therefore, affected by the following vulnerabilities:

 - Cross-site scripting (XSS) vulnerability allows remote attackers to inject arbitrary web script or HTML via a crafted URL (CVE-2011-1948)

 - Cross-site scripting (XSS) vulnerability in the safe_html filter in Products.PortalTransforms allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors (CVE-2011-1949)

 - plone.app.users allows remote authenticated users to modify the properties of arbitrary accounts via unspecified vectors, as exploited in the wild in June 2011 (CVE-2011-1950)

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 (PloneHotfix20110531) may remediate this without a version upgrade, this plugin only reports when running in Paranoid mode.

Solution

Apply the vendor hotfix (Products.PloneHotfix20110531), or upgrade to Plone version 2.5.5, 3.3.6, 4.0.4, 4.1.1 or later.
