CVE-2024-31408
📋 TL;DR
This CVE describes an OS command injection vulnerability in AIPHONE IX SYSTEM and IXG SYSTEM intercom systems. An authenticated attacker on the same network can execute arbitrary operating system commands with root privileges by sending a specially crafted request. This affects organizations using these specific AIPHONE intercom systems.
💻 Affected Systems
- AIPHONE IX SYSTEM
- AIPHONE IXG SYSTEM
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to install persistent backdoors, exfiltrate sensitive data, pivot to other network systems, or render the intercom system inoperable.
Likely Case
Attacker gains full control of the intercom system, potentially using it as a foothold to access other network resources or disrupt building security/communication functions.
If Mitigated
Attack limited to authenticated users on the same network segment, with proper network segmentation preventing lateral movement to critical systems.
🎯 Exploit Status
Exploitation requires authenticated access to the network interface of the intercom system.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisories for specific patched versions
Vendor Advisory: https://www.aiphone.net/important/20241016_1/
Restart Required: Yes
Instructions:
1. Review vendor advisories at provided URLs. 2. Download latest firmware/software from AIPHONE support site. 3. Apply update following vendor instructions. 4. Restart affected systems. 5. Verify update applied successfully.
🔧 Temporary Workarounds
Network Segmentation
allIsolate intercom systems on separate VLANs with strict firewall rules limiting access to authorized management systems only.
Access Control Hardening
allImplement strong authentication mechanisms and limit administrative access to minimum necessary personnel.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate intercom systems from critical network segments
- Deploy network-based intrusion detection/prevention systems to monitor for command injection patterns
🔍 How to Verify
Check if Vulnerable:
Check system version against vendor advisory. Systems running unpatched versions of IX SYSTEM or IXG SYSTEM are vulnerable.Check Version:
Check via device web interface or management console (vendor-specific)Verify Fix Applied:
Verify system version matches or exceeds patched version specified in vendor advisory. Test that command injection attempts are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns in system logs
- Multiple failed authentication attempts followed by successful access
- Suspicious network requests to intercom system management interfaces
Network Indicators:
- Unusual outbound connections from intercom systems
- Command injection patterns in HTTP/network traffic to intercom systems
SIEM Query:
source="intercom-system" AND (command="*;*" OR command="*|*" OR command="*`*" OR command="*$(*" OR command="*&*" OR command="*||*")
