LaikeTui 3.5.0 allows remote authenticated users to delete arbitrary files, as demonstrated by deleting install.lock in order to reinstall the product in an attacker-controlled manner. This deletion is possible via directory traversal in the uploadImg, oldpic, or imgurl parameter.
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.
