CVE-2024-9054
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary operating system commands on Microchip TimeProvider 4100 devices through improper input sanitization in configuration modules. Attackers can potentially gain full system control, access sensitive information, or disrupt time synchronization services. Organizations using TimeProvider 4100 devices for network time synchronization are affected.
💻 Affected Systems
- Microchip TimeProvider 4100
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands as root/administrator, steal sensitive configuration data, disrupt time synchronization across the network, and establish persistent backdoors.
Likely Case
Unauthorized command execution leading to service disruption, configuration modification, and potential lateral movement within the network.
If Mitigated
Limited impact through network segmentation and proper access controls, potentially only affecting the isolated time synchronization service.
🎯 Exploit Status
OS command injection vulnerabilities typically have low exploitation complexity; weaponization is likely given the critical nature of time synchronization infrastructure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.4.7
Restart Required: Yes
Instructions:
1. Download firmware version 2.4.7 from Microchip support portal. 2. Backup current configuration. 3. Apply firmware update via web interface or CLI. 4. Reboot device. 5. Verify version shows 2.4.7.
🔧 Temporary Workarounds
Network Segmentation
allIsolate TimeProvider devices from untrusted networks and limit access to authorized management systems only.
Access Control Restrictions
allImplement strict firewall rules to allow only necessary protocols (NTP, PTP) and block configuration interface access from unauthorized sources.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate TimeProvider devices from untrusted networks
- Deploy intrusion detection systems to monitor for unusual command execution patterns
🔍 How to Verify
Check if Vulnerable:
Check device firmware version via web interface (System > About) or CLI command 'show version'Check Version:
