Summary
XWiki Platform Old Core vulnerable to Authentication Bypass Using the Login Action
Details

Impact

All rights checks that would normally prevent a user from viewing a document on a wiki can be bypassed using the login action and directly specified templates. This exposes title, content and comments of any document and properties of objects (class and property name must be known, though). This is also exploitable on private wikis.

Patches

This has been patched in versions 14.2 and 13.10.4 by properly checking view rights before loading documents and disallowing non-default templates in the login, registration and skin action.

Workarounds

It would be possible to protect all templates individually by adding code to check access rights first, but due to the number of templates and the fact that some of them need to be used without view rights, this seems impractical.
