CVE-2024-39673

6.8 MEDIUM

📋 TL;DR

This vulnerability involves a serialization/deserialization mismatch in Huawei's iAware module that could allow attackers to access sensitive information. It affects Huawei devices running vulnerable versions of the iAware module. Successful exploitation could compromise service confidentiality.

💻 Affected Systems

Products:
  • Huawei devices with iAware module
Versions: Specific versions not detailed in provided references; check Huawei security bulletins for exact affected versions
Operating Systems: HarmonyOS, Android-based Huawei systems
Default Config Vulnerable: ⚠️ Yes
Notes: Affects Huawei consumer devices with the iAware module enabled. Exact device models and firmware versions should be verified through Huawei's security advisories.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could extract sensitive configuration data, authentication tokens, or other confidential information from the iAware service, potentially leading to further system compromise.

🟠

Likely Case

Information disclosure of iAware module data, which may include system configuration details or limited service information.

🟢

If Mitigated

With proper network segmentation and access controls, impact would be limited to the iAware service itself with minimal data exposure.

🌐 Internet-Facing: MEDIUM - While the vulnerability could expose sensitive information, exploitation requires specific conditions and knowledge of the iAware module.
🏢 Internal Only: MEDIUM - Internal attackers with network access could potentially exploit this to gather system information for lateral movement.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires understanding of Huawei's iAware serialization format and access to the vulnerable service. No public exploits have been reported as of the advisory date.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Huawei security bulletin for specific patched versions

Vendor Advisory: https://consumer.huawei.com/en/support/bulletin/2024/7/

Restart Required: Yes

Instructions:

1. Check Huawei security bulletin for affected device models. 2. Update device firmware through official Huawei update channels. 3. Reboot device after update. 4. Verify update through device settings.

🔧 Temporary Workarounds

Disable iAware module

android

Temporarily disable the iAware module if not required for device functionality

adb shell pm disable com.huawei.iaware

Network isolation

all

Restrict network access to devices with vulnerable iAware module

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate affected devices
  • Monitor for unusual iAware service activity and serialization attempts

🔍 How to Verify

Check if Vulnerable:

Check device firmware version against Huawei's security bulletin. For Android-based devices: adb shell getprop ro.build.version.incremental

Check Version:

adb shell getprop ro.build.version.incremental

Verify Fix Applied:

Verify firmware version has been updated to patched version listed in Huawei advisory

📡 Detection & Monitoring

Log Indicators:

  • Unusual serialization/deserialization errors in iAware logs
  • Multiple failed deserialization attempts

Network Indicators:

  • Unexpected connections to iAware service ports
  • Unusual data patterns in iAware service traffic

SIEM Query:

source="*iAware*" AND (event="deserialization_error" OR event="serialization_mismatch")
