CVE-2024-23628
📋 TL;DR
A command injection vulnerability in the Motorola MR2600 router's 'SaveStaticRouteIPv6Params' parameter allows authenticated remote attackers to execute arbitrary commands on the device. Authentication can be bypassed, enabling unauthenticated attackers to gain full control. This affects all Motorola MR2600 router users with default or vulnerable configurations.
💻 Affected Systems
- Motorola MR2600
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing persistent backdoor installation, network traffic interception, lateral movement to connected devices, and botnet recruitment.
Likely Case
Router takeover leading to DNS hijacking, credential theft from network traffic, and denial of service to connected devices.
If Mitigated
Limited impact if device is behind firewall with strict inbound filtering and authentication bypass is patched.
🎯 Exploit Status
Detailed technical analysis and proof-of-concept available in Exodus Intelligence blog posts. Authentication bypass makes exploitation straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Motorola/Arris security advisory for specific version
Vendor Advisory: https://www.arris.com/support/security-bulletins/ (check for MR2600 advisory)
Restart Required: Yes
Instructions:
1. Log into router admin interface. 2. Navigate to firmware update section. 3. Check for and apply latest firmware. 4. Reboot router after update completes. 5. Verify new firmware version is installed.
🔧 Temporary Workarounds
Disable IPv6 Static Routing
allRemove or disable IPv6 static routing functionality if not required
Network Segmentation
allPlace router in isolated network segment with strict firewall rules
🧯 If You Can't Patch
- Replace vulnerable Motorola MR2600 router with different model
- Implement strict network access controls to limit WAN exposure
🔍 How to Verify
Check if Vulnerable:
Check if router responds to crafted requests to SaveStaticRouteIPv6Params parameter with command injection payloadsCheck Version:
Log into router web interface and check System Status or About page for firmware versionVerify Fix Applied:
Verify firmware version is updated to patched release and test that command injection no longer works📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to router admin interface containing shell metacharacters
- Unexpected process execution in router logs
- Authentication bypass attempts
Network Indicators:
- Unusual outbound connections from router to unknown IPs
- DNS queries to suspicious domains from router
- Unexpected port scans originating from router
SIEM Query:
