CVE-2025-37155
📋 TL;DR
This vulnerability allows authenticated read-only SSH users to bypass access controls and gain administrator privileges on affected network management systems. It affects systems using the SSH restricted shell interface in vulnerable configurations. Organizations using HPE network management services with SSH access are at risk.
💻 Affected Systems
- HPE network management services with SSH restricted shell interface
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with administrative access, allowing data theft, configuration changes, service disruption, and lateral movement.
Likely Case
Privilege escalation from read-only to administrative access, enabling unauthorized configuration changes and data access.
If Mitigated
Limited impact if proper network segmentation, least privilege access, and monitoring are implemented.
🎯 Exploit Status
Requires authenticated read-only SSH access; exploitation likely involves specific commands or sequences to bypass restrictions
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check HPE advisory for specific patched versions
Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04888en_us&docLocale=en_US
Restart Required: Yes
Instructions:
1. Review HPE advisory for affected versions. 2. Apply recommended patches from HPE. 3. Restart affected services. 4. Verify patch application.
🔧 Temporary Workarounds
Restrict SSH access
linuxLimit SSH access to trusted IPs and users only
# In sshd_config: AllowUsers trusted_user
# In firewall: iptables -A INPUT -p tcp --dport 22 -s trusted_ip -j ACCEPT
Disable SSH restricted shell if unused
linuxRemove or disable the vulnerable SSH restricted shell interface
# Comment out or remove restricted shell configuration in sshd_config
🧯 If You Can't Patch
- Implement strict network segmentation to isolate affected systems
- Enforce least privilege: remove or restrict read-only SSH user accounts
🔍 How to Verify
Check if Vulnerable:
Check if system runs affected HPE network management services with SSH restricted shell; review HPE advisory for version detailsCheck Version:
# Check HPE service version: consult HPE documentation for specific version check commandsVerify Fix Applied:
Verify patch version matches HPE's fixed release; test that read-only users cannot execute administrative commands📡 Detection & Monitoring
Log Indicators:
- Unusual SSH login attempts by read-only users
- Privilege escalation attempts in system logs
- Commands executed by read-only users that exceed permissions
Network Indicators:
- SSH connections from unexpected sources to management interfaces
- Anomalous traffic patterns post-SSH login
SIEM Query:
