CVE-2025-47819
📋 TL;DR
Flock Safety Gunshot Detection devices before version 1.3 have an improperly secured on-chip debug interface that allows unauthorized access. This vulnerability enables attackers with physical or network access to potentially gain root shell access to the device. All Flock Safety Gunshot Detection devices running firmware versions before 1.3 are affected.
💻 Affected Systems
- Flock Safety Gunshot Detection devices
- Flock Safety Raven Gunshot Detection System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full root access to the device, allowing them to modify device functionality, install persistent malware, access sensitive data, or use the device as a foothold into connected networks.
Likely Case
Local attackers with physical access or network access to the debug interface can gain unauthorized shell access to manipulate device operations and potentially extract sensitive information.
If Mitigated
With proper physical security and network segmentation, the attack surface is reduced to only those with direct physical access to the device.
🎯 Exploit Status
Public research demonstrates successful exploitation via the debug interface without authentication. Physical access or network access to the debug port is required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.3
Vendor Advisory: https://www.flocksafety.com/articles/gunshot-detection-and-license-plate-reader-security-alert
Restart Required: Yes
Instructions:
1. Contact Flock Safety support to schedule firmware update. 2. Deploy firmware version 1.3 to all affected devices. 3. Verify successful update and device functionality post-update.
🔧 Temporary Workarounds
Physical Security Controls
allImplement strict physical access controls to prevent unauthorized physical access to devices
Network Segmentation
allIsolate devices on separate network segments with strict firewall rules preventing access to debug interfaces
🧯 If You Can't Patch
- Implement strict physical security measures to prevent unauthorized device access
- Deploy network segmentation and firewall rules to block access to device debug interfaces
🔍 How to Verify
Check if Vulnerable:
Check device firmware version via Flock Safety management interface or console. If version is below 1.3, device is vulnerable.Check Version:
Check via Flock Safety management portal or device console interface (vendor-specific commands)Verify Fix Applied:
Confirm firmware version shows 1.3 or higher in device management interface. Test debug interface access is properly restricted.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to debug interfaces
- Unexpected device reboots or configuration changes
- Unusual network traffic from devices
Network Indicators:
- Unexpected connections to device debug ports
- Traffic patterns indicating shell access to devices
