CVE-2021-45448

Pentaho Business Analytics<br /> Server versions before 9.2.0.2 and 8.3.0.25 using the Pentaho <br /> Analyzer plugin exposes a service endpoint for templates which allows a <br /> user-supplied path to access resources that are out of bounds. <br /> <br /> The software uses external input to construct a pathname that is intended to identify a file or <br /> directory that is located underneath a restricted parent directory, but the software does not <br /> properly neutralize special elements within the pathname that can cause the pathname to <br /> resolve to a location that is outside of the restricted directory.  By using special elements such as <br /> ".." and "/" separators, attackers can escape outside of the restricted <br /> location to access files or directories that are elsewhere on the <br /> system.<br /> <br /> <br /> <br />
