The functionality for file download in HGiga OAKlouds' certain modules contains an Arbitrary File Read and Delete vulnerability. Attackers can put file path in specific request parameters, allowing them to download the file without login. Furthermore, the file will be deleted after being downloaded.
Solution:
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.
