Associated Vulnerability

Title:Spring Framework 代码注入漏洞 (CVE-2022-22965)
Description:A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to the exploit. However, the nature of the vulnerability is more general, and there may be other ways to exploit it.

### Vulnerability detection
#### POC
It is recommended to use POC to detect the target. Its advantage is to verify whether the vulnerability exists based on [DNSLOG](https://dig.pm/), and it will not modify the log configuration of tomcat

```bash
python3 cve-2022-22965-poc.py -url https://example.com/
python3 cve-2022-22965-poc.py -file file.txt
```

#### Fuzz

##### POC
*Add common routs on line 13*
```python
routs = ['env',]
```

##### EXP Fuzz
*Add common path on line 12*

```python
path = ['root',]
````


* WARNING:*

- This EXP will write unsuccessful http requests together to a file.
- This EXP changes the tomcat configuration.
