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 9.5.0 版本之前存在不可信数据反序列化漏洞。Kiteworks Core 中的反序列化缺陷可能在特定条件下允许攻击者构造的数据被不安全地反序列化，从而可能导致在设备上执行远程代码。利用该漏洞的前提是攻击者能够先影响受影响的数据，因此该问题无法单独被利用。

Vulnerability Title
Kiteworks Core deserialization of untrusted data
Source: CVE Program / CVE List V5
Vulnerability Description
Kiteworks Core before version 9.5.0 is vulnerable to Deserialization of Untrusted Data. A deserialization weakness in Kiteworks Core could, under certain conditions, allow crafted data to be deserialized unsafely, potentially resulting in remote code execution on the appliance. Exploitation depends on an attacker first being able to influence the affected data, so this issue is not exploitable on its own.
