Vulnerability Title
NitroShare Desktop 0.3.4 Path Traversal via LAN File Transfer Server
Source: CVE Program / CVE List V5
Vulnerability Description
NitroShare Desktop through 0.3.4 contains a path traversal vulnerability in its LAN file transfer server that allows unauthenticated attackers on the same network to write arbitrary files by sending a crafted filename containing directory traversal sequences in the JSON item header name field. Attackers can exploit the lack of path validation to write files outside the transfer root directory to arbitrary locations the current user has write access, including the Windows Startup folder, enabling persistent code execution on the next user login.
