Description

Pentaho Business Analytics
Server versions before 9.2.0.2 and 8.3.0.25 using the Pentaho
Analyzer plugin exposes a service endpoint for templates which allows a
user-supplied path to access resources that are out of bounds. 

The software uses external input to construct a pathname that is intended to identify a file or
directory that is located underneath a restricted parent directory, but the software does not
properly neutralize special elements within the pathname that can cause the pathname to
resolve to a location that is outside of the restricted directory.  By using special elements such as
".." and "/" separators, attackers can escape outside of the restricted
location to access files or directories that are elsewhere on the
system.
