CVE-2025-37148
📋 TL;DR
An unauthenticated remote attacker can send specially crafted ethernet frames to vulnerable ArubaOS devices, causing denial of service that requires manual intervention to restore. This affects ArubaOS 8 Instant and ArubaOS 10 wireless access points and controllers.
💻 Affected Systems
- ArubaOS 8 Instant
- ArubaOS 10
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact
Worst Case
Complete network service disruption requiring physical console access or power cycling to restore functionality, potentially affecting entire wireless networks.
Likely Case
Targeted DoS attacks against specific vulnerable devices causing service interruptions until manual recovery.
If Mitigated
Minimal impact with proper network segmentation and access controls limiting exposure to untrusted networks.
🎯 Exploit Status
Exploitation requires sending malformed ethernet frames to vulnerable devices. No authentication required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check HPE advisory for specific patched versions
Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04958en_us&docLocale=en_US
Restart Required: No
Instructions:
1. Review HPE advisory for affected versions. 2. Download and apply appropriate firmware updates. 3. Verify update applied successfully.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to management interfaces and wireless infrastructure to trusted networks only
Access Control Lists
allImplement ACLs to limit which source IPs can communicate with vulnerable devices
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable devices from untrusted networks
- Deploy network monitoring and intrusion detection to alert on DoS attempts
🔍 How to Verify
Check if Vulnerable:
