Authentication Bypass by Alternate Name vulnerability in Apache Shiro.
This issue affects Apache Shiro: before 2.0.7.
Users are recommended to upgrade to version 2.0.7, which fixes the issue.
The issue only effects static files. If static files are served from a case-insensitive filesystem,
such as default macOS setup, static files may be accessed by varying the case of the filename in the request.
If only lower-case (common default) filters are present in Shiro, they may be bypassed this way.
Shiro 2.0.7 and later has a new parameters to remediate this issue
shiro.ini: filterChainResolver.caseInsensitive = true
application.propertie: shiro.caseInsensitive=true
Shiro 3.0.0 and later (upcoming) makes this the default.

Apache Shiro before 1.13.0 or 2.0.0-alpha-4, may be susceptible to a path traversal attack that results in an authentication bypass when used together with path rewriting
Mitigation: Update to Apache Shiro 1.13.0+ or 2.0.0-alpha-4+, or ensure `blockSemicolon` is enabled (this is the default).
