Description Vasyl Kaigorodov 2015-01-15 14:05:47 UTC 
A vulnerability has been found in the mod_jk connector relating to the use of JkMount and JkUnmount.

A JkUnmount rule for a subtree of a previous JkMount rule could be ignored. This could allow a remote attacker to potentially access a private artifact in a directory tree that would otherwise not be accessible to them.

If you use a mount rule like

JkMount /a/b/* myworker

Then 

JkUnmount /a/b/private/* myworker

Artifacts in the private folder would still be accessible.

This vulnerability affected all versions of mod_jk.
