CVE-2016-1997
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary commands on affected HPE Operations Orchestration systems by sending a malicious serialized Java object. The flaw exists in the Apache Commons Collections library used by these products. Organizations running HPE Operations Orchestration 10.x before 10.51 or content before 1.7.0 are affected.
💻 Affected Systems
- HPE Operations Orchestration
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with remote code execution as privileged user, leading to data theft, lateral movement, and persistent backdoor installation.
Likely Case
Remote attackers gain shell access to the Operations Orchestration server, enabling them to execute commands, access sensitive orchestration data, and potentially pivot to other systems.
If Mitigated
With proper network segmentation and access controls, impact is limited to the Operations Orchestration environment only.
🎯 Exploit Status
This is a well-known Java deserialization vulnerability with multiple public exploit tools available. Attackers can use ysoserial or similar tools to generate payloads.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: HPE Operations Orchestration 10.51 or later, Operations Orchestration content 1.7.0 or later
Vendor Advisory: https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05050545
Restart Required: Yes
Instructions:
1. Download and install HPE Operations Orchestration 10.51 or later from HPE support portal. 2. Update Operations Orchestration content to version 1.7.0 or later. 3. Restart all Operations Orchestration services. 4. Verify the update was successful.
🔧 Temporary Workarounds
Network segmentation and access control
allRestrict network access to Operations Orchestration servers to only trusted management networks and required users.
Application layer filtering
allImplement WAF rules to block serialized Java objects or known exploit patterns targeting Commons Collections.
🧯 If You Can't Patch
- Isolate the Operations Orchestration server in a dedicated network segment with strict firewall rules
- Implement intrusion detection/prevention systems to monitor for exploit attempts and block malicious traffic
🔍 How to Verify
Check if Vulnerable:
Check Operations Orchestration version: If version is 10.x and less than 10.51, or content version is less than 1.7.0, system is vulnerable.Check Version:
Check version through Operations Orchestration administration interface or consult HPE documentation for version verification commands specific to your deployment.Verify Fix Applied:
Verify Operations Orchestration version is 10.51 or higher and content version is 1.7.0 or higher via administration console or version check commands.📡 Detection & Monitoring
Log Indicators:
- Unusual Java deserialization errors in application logs
- Unexpected process execution from Operations Orchestration service account
- Network connections from Operations Orchestration server to unusual external IPs
Network Indicators:
- Inbound connections to Operations Orchestration ports (typically 8080, 8443) followed by outbound connections to command and control servers
- Traffic patterns matching known Java deserialization exploit payloads
