Sunlogin Sunflower Simplified (aka Sunflower Simple and Personal) 1.0.1.43315 is vulnerable to a path traversal issue. A remote and unauthenticated attacker can execute arbitrary programs on the victim host by sending a crafted HTTP request, as demonstrated by /check?cmd=ping../ followed by the pathname of the powershell.exe program.
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.
