CVE-2025-68963
📋 TL;DR
This CVE describes a man-in-the-middle (MITM) vulnerability in the Clone module that could allow attackers to intercept and potentially modify communications. The vulnerability affects service confidentiality, meaning sensitive data could be exposed during transmission. Organizations using the affected Clone module implementation are at risk.
💻 Affected Systems
- Clone module implementation from Huawei
📦 What is this software?
Emui by Huawei
Harmonyos by Huawei
⚠️ Risk & Real-World Impact
Worst Case
Attackers could intercept sensitive data in transit, potentially exposing credentials, personal information, or proprietary business data.
Likely Case
Attackers on the same network segment could intercept unencrypted or weakly authenticated communications between systems using the Clone module.
If Mitigated
With proper network segmentation, encryption, and certificate validation, the risk is significantly reduced to minimal data exposure.
🎯 Exploit Status
MITM attacks typically require network access and ability to intercept traffic, but no authentication bypass is needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in provided reference
Vendor Advisory: https://consumer.huawei.com/en/support/bulletin/2026/1//
Restart Required: Yes
Instructions:
1. Check Huawei advisory for affected products. 2. Apply recommended patches or updates. 3. Restart affected services/systems. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Implement TLS/SSL encryption
allEnforce encrypted communications for all Clone module traffic
Network segmentation
allIsolate systems using Clone module from untrusted networks
🧯 If You Can't Patch
- Implement strict network access controls to limit who can communicate with Clone module systems
- Deploy certificate pinning or strong certificate validation for Clone module communications
🔍 How to Verify
Check if Vulnerable:
