Vulnerability Title
XStream is vulnerable to an Arbitrary Code Execution attack
来源: 美国国家漏洞数据库 NVD
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 load and execute arbitrary code from a remote host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.

| # | POC 描述 | 源链接 | 神龙链接 |
|---|---|---|---|
| 1 | XStream 1.4.18 is susceptible to remote code execution. An attacker can execute commands of the host by manipulating the processed input stream, thereby making it possible to obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site. Setups which followed XStream's security recommendations with an allow-list are not impacted. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2021/CVE-2021-39146.yaml | POC详情 |
