Plone releases fixes for 24 vulnerabilities
After last week's alert that Zope and the Plone CMS are vulnerable to 24 security holes that could have led to privilege escalation and code injection, the developers have now released a hotfix for Plone that closes them. The hotfix has been tested with Plone 4.2, Plone 4.1, Plone 4, Plone 3, Plone 2.5 and Plone 2.1. An FAQ and other information on the problems is also available.
The list of flaws is, as expected, extensive: issues include the ability for anonymous users to execute arbitrary Python in the admin interface, crafting of URLs which can log users out, an ability to escape the Python sandbox, XSS issues, permissions bypasses, denial of service through unsanitised inputs or by requesting large collections, anonymous manipulation of content item titles, unauthorised downloading of BLOB content, password timing attacks and more.
