CVE-2017-8990
📋 TL;DR
This CVE describes a remote code execution vulnerability in HPE Intelligent Management Center Wireless Service Manager (WSM) software. Attackers can exploit this to execute arbitrary code on affected systems, potentially gaining full control. Organizations running HPE iMC WSM versions earlier than 7.3 E0506P01 are affected.
💻 Affected Systems
- HPE Intelligent Management Center Wireless Service Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to install malware, steal sensitive data, pivot to other network systems, and maintain persistent access.
Likely Case
Attackers gain administrative control over the WSM system, allowing them to manipulate wireless network configurations, intercept traffic, or use the system as a foothold for further attacks.
If Mitigated
With proper network segmentation and access controls, impact is limited to the WSM system itself without lateral movement to critical infrastructure.
🎯 Exploit Status
The high CVSS score (9.8) suggests exploitation is relatively straightforward. No authentication is required, making this particularly dangerous.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: WSM 7.3 E0506P01 or later
Vendor Advisory: https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03852en_us
Restart Required: Yes
Instructions:
1. Download patch E0506P01 or later from HPE support portal. 2. Backup current configuration and data. 3. Apply the patch following HPE's installation guide. 4. Restart the iMC WSM service. 5. Verify successful installation by checking version.
🔧 Temporary Workarounds
Network Segmentation
allIsolate the WSM system from untrusted networks and restrict access to authorized IP addresses only.
Firewall Rules
allImplement strict firewall rules to block external access to the WSM management interface.
🧯 If You Can't Patch
- Immediately isolate the WSM system from all untrusted networks and internet access
- Implement strict network access controls allowing only necessary administrative connections from trusted IPs
🔍 How to Verify
Check if Vulnerable:
Check the iMC WSM version via the web interface or by examining installation files. If version is earlier than 7.3 E0506P01, the system is vulnerable.Check Version:
Check via iMC web interface: Login > Help > About, or examine version files in installation directory.Verify Fix Applied:
After patching, verify the version shows 7.3 E0506P01 or later in the iMC WSM web interface or about dialog.📡 Detection & Monitoring
Log Indicators:
- Unusual process creation events
