概要

Impact

The create action is vulnerable to a CSRF attack, allowing script and thus remote code execution when targeting a user with script/programming right, thus compromising the confidentiality, integrity and availability of the whole XWiki installation. To reproduce, the XWiki syntax [[image:path:/xwiki/bin/create/Foo/WebHome?template=&parent=Main.WebHome&title=$services.logging.getLogger(%22foo%22).error(%22Script%20executed!%22)]] can be added to any place that supports XWiki syntax like a comment. When a user with script right views this image and a log message ERROR foo - Script executed! appears in the log, the XWiki installation is vulnerable.

Patches

This has been patched in XWiki 14.10.9 and 15.4RC1 by requiring a CSRF token for the actual page creation.

Workarounds

There are no known workarounds.
