CVE-2026-66050— NitroShare 路径遍历漏洞

NitroShare Desktop 0.3.4 Path Traversal via LAN File Transfer Server

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.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

对路径名的限制不恰当(路径遍历)

NitroShare 路径遍历漏洞

NitroShare NitroShare是NitroShare组织的一款文件共享桌面工具。 NitroShare Desktop 0.3.4及之前版本存在路径遍历漏洞，该漏洞源于其LAN文件传输服务器存在路径遍历漏洞，缺乏对路径的验证，导致未经身份验证的攻击者可通过发送包含目录遍历序列的特制文件名（JSON item header name字段）写入任意文件。
