CVE-2017-16102: Directory Traversal in serverhuwenhui

The vulnerability fundamentally stems from improper path sanitization when handling user-controlled input (URL paths). While the exact code isn't available, the pattern matches classic path traversal vulnerabilities where: 1) The request handler directly uses req.url without sanitization 2) Path resolution functions (like path.join()) combine user input with base directories without preventing parent directory escapes 3) File system operations (fs.readFile()) are called with untrusted paths. These two functional areas must exist in any HTTP file server implementation and would be the logical points of failure given the described vulnerability.
