CVE-2025-37159
📋 TL;DR
This vulnerability allows an authenticated remote attacker to hijack active user sessions in the AOS-CX OS web management interface, potentially leading to unauthorized access to sensitive configuration data. It affects systems running vulnerable versions of AOS-CX OS with the web management interface enabled.
💻 Affected Systems
- AOS-CX OS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could gain persistent unauthorized access to the management interface, modify network configurations, disrupt operations, or exfiltrate sensitive data.
Likely Case
An authenticated attacker hijacks a session to view or tamper with configuration settings, potentially causing service disruptions or unauthorized changes.
If Mitigated
With proper access controls and monitoring, impact is limited to temporary session compromise, quickly detected and contained.
🎯 Exploit Status
Exploitation requires authenticated access, making it less trivial but feasible for attackers with initial credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check HPE advisory for specific fixed 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. Download and apply the recommended patch from HPE support. 3. Restart the system to ensure changes take effect.
🔧 Temporary Workarounds
Disable Web Management Interface
allTemporarily disable the web interface to prevent exploitation until patching is possible.
no web-management enable
Restrict Access to Management Interface
allLimit network access to the web interface using firewall rules or ACLs to trusted IPs only.
