GibbonEdu Gibbon through version 25.0.0 allows Directory Traversal via the report template builder. An attacker can create a new Asset Component. The templateFileDestination parameter can be set to an arbitrary pathname (and extension). This allows creation of PHP files outside of the uploads directory, directly in the webroot.
The product 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 product 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.
