cPanel before 64.0.21 allows certain file-read operations via a Serverinfo_manpage API call (SEC-252).
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.
