Technical details

Plone before version 4.2.3 and 4.3 beta 1 contains a cross-site request forgery (CSRF) vulnerability in the batch ID change script (renameObjectsByPaths.py). The vulnerability exists because the script does not properly enforce CSRF protections on content title modification requests. An unauthenticated remote attacker can craft a malicious web page that, when visited by a logged-in administrator, will execute a request to change content titles. No special preconditions beyond admin session presence are required. The attacker can change titles of arbitrary content items, compromising site data integrity. Patches are available in Plone 4.2.3 and 4.3 beta 1 and later.
