Directory traversal vulnerability in Kaseya Virtual System Administrator (VSA) 7.0.0.0 before 7.0.0.33, 8..0.0.0 before 8.0.0.23, 9.0.0.0 before 9.0.0.19, and 9.1.0.0 before 9.1.0.9 allows remote authenticated users to write to and execute arbitrary files due to insufficient restrictions in file paths to json.ashx.
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.
