CVE-2020-9115
📋 TL;DR
This is a command injection vulnerability in Huawei ManageOne management software that allows authenticated attackers with high privileges to execute arbitrary commands on affected systems. It affects specific versions of ManageOne 6.5.1.1 and 8.0.x through insufficient input validation in the plug-in component. Organizations using these vulnerable ManageOne versions for infrastructure management are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands with high privileges, potentially leading to data theft, system destruction, or lateral movement within the network.
Likely Case
Privileged authenticated attackers could execute commands to modify configurations, exfiltrate sensitive management data, or disrupt management operations.
If Mitigated
With proper access controls limiting high-privilege accounts and network segmentation, impact would be limited to the management system itself.
🎯 Exploit Status
Exploitation requires high-privilege access to the ManageOne system and knowledge of vulnerable plug-in operations. No public exploit code has been identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Update to versions beyond those listed in affected versions
Vendor Advisory: https://www.huawei.com/en/psirt/security-advisories/huawei-sa-20201125-01-commandinjection-en
Restart Required: Yes
Instructions:
1. Check current ManageOne version. 2. Contact Huawei support for appropriate patch/upgrade. 3. Apply the update following Huawei's official documentation. 4. Restart the ManageOne system as required.
🔧 Temporary Workarounds
Restrict High-Privilege Access
allLimit the number of users with high privileges to only those who absolutely need them for ManageOne operations.
Network Segmentation
allIsolate ManageOne management network from production systems to limit potential lateral movement.
🧯 If You Can't Patch
- Implement strict access controls and monitor all high-privilege user activities on ManageOne systems
- Deploy network-based intrusion detection to monitor for command injection patterns in ManageOne traffic
🔍 How to Verify
Check if Vulnerable:
Check ManageOne version via the system administration interface or console. If version matches affected range (6.5.1.1.B010-B050, 8.0.0, 8.0.1), system is vulnerable.Check Version:
Check through ManageOne web interface or consult Huawei documentation for version query commands specific to your deployment.Verify Fix Applied:
After patching, verify the version no longer matches affected versions and test plug-in component operations for proper input validation.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns in system logs
- Multiple failed authentication attempts followed by successful high-privilege access
- Abnormal plug-in component operations
Network Indicators:
- Unusual outbound connections from ManageOne system
- Command injection patterns in HTTP requests to ManageOne
