Path Traversal in XWiki Platform

Impact

One can ask for any file located in the classloader using the template API and a path with ".." in it. For example

{{template name="../xwiki.hbm.xml"/}}

To our knownledge none of the available files of the classloader in XWiki Standard contain any strong confidential data, hence the low confidentiality value of this advisory.

Patches

The issue is patched in versions 14.0 and 13.10.3.

Workarounds

There's no easy workaround for this issue, administrators should upgrade their wiki.
