Quick assessment

Affected
Kiteworks Core
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Kiteworks Core 在版本 9.5.0 之前存在任意文件写入漏洞。由于 Kiteworks 管理导出功能中对用户提供的文件路径缺乏适当的限制，经过身份验证的管理员可能能够将文件写入底层主机上的任意位置，从而可能导致在设备上执行命令。利用该漏洞需要一个已存在的、经过身份验证且具有受影响导出功能访问权限的管理员账户。

Vulnerability Description
Kiteworks Core before version 9.5.0 is vulnerable to Arbitrary File Write.

Exploitation requires an existing, authenticated administrative account with access to the affected export function.
