CVE-2016-4368

9.8 CRITICAL

📋 TL;DR

This vulnerability allows remote attackers to execute arbitrary commands on affected HPE Universal CMDB and Universal Discovery systems by sending a specially crafted serialized Java object. The flaw exists in the Apache Commons Collections library used by these products, enabling remote code execution without authentication. Organizations running HPE Universal CMDB 10.0-10.21, Universal CMDB Configuration Manager 10.0-10.21, or Universal Discovery 10.0-10.21 are affected.

💻 Affected Systems

Products:
  • HPE Universal CMDB
  • HPE Universal CMDB Configuration Manager
  • HPE Universal Discovery
Versions: 10.0 through 10.21
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: All installations within the affected version range are vulnerable regardless of configuration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing attackers to execute arbitrary commands with system privileges, potentially leading to data theft, lateral movement, or deployment of ransomware.

🟠

Likely Case

Remote code execution leading to installation of backdoors, credential harvesting, or deployment of cryptocurrency miners on vulnerable systems.

🟢

If Mitigated

Limited impact if systems are patched, network segmentation is in place, and proper monitoring detects exploitation attempts.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: CONFIRMED
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

This vulnerability leverages the well-known Apache Commons Collections deserialization vulnerability (CVE-2015-4852) and has publicly available exploit code.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 10.22 or later

Vendor Advisory: https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05164408

Restart Required: Yes

Instructions:

1. Download the patch from HPE Support Center. 2. Apply the patch following HPE's installation instructions. 3. Restart the affected services. 4. Verify the patch was successfully applied.

🔧 Temporary Workarounds

Network Segmentation

all

Restrict network access to vulnerable systems using firewalls or network segmentation.

WAF Rules

all

Implement Web Application Firewall rules to block serialized Java object payloads.

🧯 If You Can't Patch

  • Immediately isolate vulnerable systems from the internet and restrict internal network access.
  • Implement strict network monitoring and alerting for any attempts to exploit this vulnerability.

🔍 How to Verify

Check if Vulnerable:

Check the product version via the administration console or configuration files. If version is between 10.0 and 10.21 inclusive, the system is vulnerable.

Check Version:

Check the product documentation for version verification commands specific to your installation.

Verify Fix Applied:

Verify the product version is 10.22 or later after applying the patch.

📡 Detection & Monitoring

Log Indicators:

  • Unusual Java deserialization errors in application logs
  • Unexpected process execution from the application server
  • Suspicious network connections originating from the application server

Network Indicators:

  • HTTP requests containing serialized Java objects to vulnerable endpoints
  • Outbound connections from the application server to unknown external IPs

SIEM Query:

Search for: (event_source="HPE UCMDB" OR event_source="HPE UD") AND (error_message CONTAINS "deserialization" OR process_execution="unexpected")
