Description Adam Mariš 2017-09-19 12:10:55 EDT 
When using a VirtualDirContext with Apache Tomcat 7.0.0 to 7.0.80 it was possible to bypass security constraints and/or view the source code of JSPs for resources served by the VirtualDirContext using a specially crafted request.

Affected versions: 7.0.0 to 7.0.80

Comment 3 Jason Shepherd 2017-09-20 21:06:47 EDT 
VirtualDirContext is not designed to be used in Production. Also, because the information disclosed is only the source code for JSP setting this issue to WONTFIX.
Comment 6 Doran Moppert 2017-09-25 01:33:24 EDT 
Statement:

VirtualDirContext is not designed to be used in production, but only to ease development with IDEs without needing to fully republish jars in WEB-INF/lib.
