Vulnerability Title
A Server-Side Forgery Request vulnerability in XStream via HashMap unmarshaling
来源: CVE Program / CVE List V5
Vulnerability Description
XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream with a Java runtime version 14 to 8. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the [Security Framework](https://x-stream.github.io/security.html#framework), you will have to use at least version 1.4.18.

二、漏洞 CVE-2021-39152 的公开POC
| # | POC 描述 | 源链接 | 神龙链接 |
|---|---|---|---|
| 1 | XStream before 1.4.18 is susceptible to server-side request forgery. An attacker can request data from internal resources that are not publicly available by manipulating the processed input stream with a Java runtime version 14 to 8. This makes it possible to obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2021/CVE-2021-39152.yaml | POC详情 |
