CVE-2024-47127
📋 TL;DR
This vulnerability in the goTenna Pro App allows attackers to inject forged messages with arbitrary group IDs and callsigns into goTenna mesh networks using software-defined radio. It affects users operating in unencrypted environments or where encryption has been compromised. The vulnerability enables message spoofing and network disruption.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of mesh network communications, allowing attackers to impersonate legitimate users, inject false information, disrupt emergency communications, or conduct surveillance operations.
Likely Case
Message spoofing and injection leading to misinformation, operational disruption, and potential social engineering attacks within affected mesh networks.
If Mitigated
Limited impact when using strong encryption with properly managed keys and updated software, though physical proximity requirements remain.
🎯 Exploit Status
Requires software-defined radio equipment and physical proximity to target mesh network. No authentication needed for message injection in vulnerable configurations.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Current release (specific version not specified in advisory)
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-24-270-04
Restart Required: Yes
Instructions:
1. Update goTenna Pro App to latest version from official app store. 2. Restart the application. 3. Ensure encryption keys are properly managed, preferably via QR code scanning for sensitive operations.
🔧 Temporary Workarounds
Enable Strong Encryption
allAlways operate goTenna Pro App with encryption enabled and use QR code scanning for key exchange
Network Segmentation
allLimit mesh network range and physical access to sensitive operational areas
🧯 If You Can't Patch
- Operate only with strong encryption using QR-scanned keys for all communications
- Implement physical security measures to prevent unauthorized radio equipment near operational areas
🔍 How to Verify
Check if Vulnerable:
Check app version in settings. If not on latest version and operating without encryption or with compromised encryption, system is vulnerable.Check Version:
Check within goTenna Pro App settings under 'About' or version informationVerify Fix Applied:
Verify app is updated to latest version and encryption is properly configured with QR-scanned keys.📡 Detection & Monitoring
