NitroShare Desktop versions up to and including 0.3.4 are vulnerable to a path traversal flaw in their LAN file transfer server, allowing unauthenticated attackers on the same network to craft malicious filenames containing directory traversal sequences within the JSON item header. Exploiting this, attackers can write arbitrary files outside the intended transfer root to any location the current user has write access, including the Windows Startup folder, leading to persistent code execution upon user login.
