CVE-2025-37161
📋 TL;DR
An unauthenticated remote denial-of-service vulnerability in HPE web management interfaces allows attackers to crash affected systems, requiring manual intervention to restore service. This affects HPE networking products with vulnerable web interfaces exposed to untrusted networks. Network operations can be disrupted until systems are manually rebooted.
💻 Affected Systems
- HPE networking products with web-based management interfaces

⚠️ Risk & Real-World Impact
Worst Case
Critical network infrastructure becomes completely unavailable, requiring physical access to reboot devices, causing extended service outages.
Likely Case
Targeted systems crash and become unresponsive, disrupting network services until administrators manually intervene.
If Mitigated
With proper network segmentation and access controls, impact is limited to isolated management networks with minimal service disruption.
🎯 Exploit Status
Unauthenticated exploitation makes this particularly dangerous for exposed interfaces
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check HPE advisory for specific firmware versions
Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04970en_us&docLocale=en_US
Restart Required: Yes
Instructions:
1. Review HPE advisory for affected products. 2. Download appropriate firmware update from HPE support portal. 3. Apply firmware update following HPE documentation. 4. Reboot device to activate new firmware.
🔧 Temporary Workarounds
Disable Web Management Interface
allDisable the vulnerable web interface and use alternative management methods
Refer to HPE product documentation for disabling web interface commands
Restrict Network Access
allLimit access to management interfaces to trusted IP addresses only
Configure ACLs to restrict management interface access to specific source IPs
🧯 If You Can't Patch
- Isolate management interfaces on separate VLANs with strict access controls
- Implement network monitoring for DoS attempts against management interfaces
🔍 How to Verify
Check if Vulnerable:
Check device model and firmware version against HPE advisory listCheck Version:
show version (or equivalent for specific HPE device)Verify Fix Applied:
Verify firmware version has been updated to patched version listed in HPE advisory📡 Detection & Monitoring
Log Indicators:
- Multiple connection attempts to web interface followed by system crash
- Unexpected device reboots or unresponsiveness
Network Indicators:
- Unusual traffic patterns to management interface ports
- Multiple HTTP requests to management URLs from single sources
