- Summary
- XWiki Platform Old Core: Resource path traversal via /skin/ action endpoint in Jetty 12+
- Details
-
Impact
With Jetty 12+ a user can craft a URL to access any resource the Jetty instance is allowed to access.
For example
http://[host]/xwiki/bin/skin/..%252f/..%252f..%252f..%252f..%252f..%252f..%252f..%252fetc/passwdallows downloading the content of the /etc/passwd file, provided Jetty is allowed to read it, and if your XWiki webapp is located exactly 5 levels below/(like/var/lib/jetty/webapps/xwiki, which is the case in the docker image, for example).Another example which does not go out of the XWiki webapp, but it's still a vulnerability (since users should not be allowed to access Hibernate or XWiki configuration files) is
http://[host]/xwiki/bin/skin/..%252f/..%252fWEB-INF/xwiki.cfg.Patches
This vulnerability has been patched in XWiki 17.10.5 and 18.2.0.
Workarounds
A possible workaround is to use a different application server, like Jetty < 12 (in the case of XWiki < 17) or Tomcat, which don't seem to be impacted.
