Vulnerability from cnvd

Title: XStream远程代码执行漏洞（CNVD-2021-49071）

Description:

XStream是一个Java类库，主要用来将Java对象序列化成XML或反序列化为对象，可处理的对象类型几乎没有限制。

XStream 1.4.16及之前的版本中存在远程代码执行漏洞。该漏洞源于XStream解组XML时，若处理的数据流中包含重新创建已写入对象的类型信息，XStream将基于这些类型信息创建新的实例。攻击者可操纵经过处理的输入流，替换或注入代码，通过构造恶意XML利用该漏洞执行主机命令。

Severity ?

7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-94 - Improper Control of Generation of Code ('Code Injection')
CWE-502 - Deserialization of Untrusted Data

Summary

XStream is software for serializing Java objects to XML and back again. A vulnerability in XStream versions prior to 1.4.17 may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types is affected. The vulnerability is patched in version 1.4.17.
