CVE-2024-34050
📋 TL;DR
This vulnerability in rimedo-ts 0.1.1 allows attackers to cause a denial-of-service (DoS) by triggering a slice bounds out-of-range panic in the reader.go component. It affects systems running the Open Networking Foundation SD-RAN Rimedo rimedo-ts software, specifically version 0.1.1. The vulnerability occurs when processing malformed input that causes array index errors in the uint64 conversion function.
💻 Affected Systems
- Open Networking Foundation SD-RAN Rimedo rimedo-ts
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption of the SD-RAN rimedo-ts component, potentially affecting network slicing functionality in 5G networks and causing cascading failures in dependent systems.
Likely Case
Service crash and restart of the rimedo-ts component, resulting in temporary disruption of network slicing operations until the process recovers.
If Mitigated
Controlled restart of the affected component with minimal service interruption if proper monitoring and auto-restart mechanisms are in place.
🎯 Exploit Status
The vulnerability can be triggered by sending malformed input to the affected function, but specific exploit details are not publicly documented. The CWE-129 classification indicates improper validation of array index bounds.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub repository for latest version > 0.1.1
Vendor Advisory: https://github.com/onosproject/rimedo-ts/issues/16
Restart Required: Yes
Instructions:
1. Check the rimedo-ts GitHub repository for the latest release. 2. Update to a version that includes bounds checking fixes. 3. Restart the rimedo-ts service. 4. Verify the fix by testing with valid and malformed inputs.
🔧 Temporary Workarounds
Input Validation Wrapper
linuxImplement input validation before data reaches the vulnerable function to ensure array bounds are checked
# Custom implementation required based on deployment
Process Monitoring and Auto-restart
linuxConfigure monitoring to detect and automatically restart the rimedo-ts process if it crashes
systemctl enable rimedo-ts
systemctl start rimedo-ts
# Configure monitoring in systemd or supervisor
🧯 If You Can't Patch
- Implement network segmentation to isolate rimedo-ts from untrusted networks
- Deploy rate limiting and input sanitization at the network perimeter
🔍 How to Verify
Check if Vulnerable:
Check the rimedo-ts version: grep -r 'version' /path/to/rimedo-ts/config or check package managerCheck Version:
rimedo-ts --version 2>/dev/null || grep version /path/to/rimedo-ts/README.mdVerify Fix Applied:
Test with sample inputs that previously caused crashes and verify the service remains stable📡 Detection & Monitoring
Log Indicators:
- panic: runtime error: slice bounds out of range
- rimedo-ts process crashes with stack trace showing reader.go
- unexpected service restarts
Network Indicators:
- Unusual traffic patterns to rimedo-ts service port
- Connection attempts with malformed data packets
