# N/A
## 概述
在特定配置下，攻击者可以利用Apache Tomcat中的远程代码执行漏洞进行攻击。该漏洞要求攻击者能够控制服务器上的文件内容及其名称，并知道文件存储位置的相对路径。
## 影响版本
- 10.0.0-M1 到 10.0.0-M4
- 9.0.0.M1 到 9.0.34
- 8.5.0 到 8.5.54
- 7.0.0 到 7.0.103
## 细节
- 攻击者需要能够控制服务器上的文件内容和文件名称。
- 服务器配置使用PersistenceManager和FileStore。
- PersistenceManager配置为`sessionAttributeValueClassNameFilter="null"`（默认值，除非使用SecurityManager）或允许反序列化的过滤器松弛。
- 攻击者需要知道文件存储位置的相对路径。
## 影响
如果上述条件全部满足，攻击者可以通过精心构造的请求触发远程代码执行，从而执行任意代码。

Note that all of conditions a) to d) must be true for the attack to succeed. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2020/CVE-2020-9484.yaml | POC详情 |
