nhttpd in Nostromo before 2.1 is vulnerable to a path traversal that may allow an attacker to execute arbitrary commands on the remote server. The vulnerability occurs when the homedirs option is used.
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.
