CVE-2020-4208
📋 TL;DR
IBM Spectrum Protect Plus versions 10.1.0 through 10.1.5 contain hard-coded credentials that could allow attackers to authenticate to the system, communicate with external components, or decrypt internal data. This affects all deployments using vulnerable versions, potentially exposing backup data and administrative access.
💻 Affected Systems
- IBM Spectrum Protect Plus
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of backup infrastructure, data exfiltration, ransomware deployment across backup targets, and lateral movement to production systems.
Likely Case
Unauthorized access to backup data, potential credential harvesting, and administrative control over backup operations.
If Mitigated
Limited impact if system is isolated, monitored, and access controls prevent credential usage from unauthorized networks.
🎯 Exploit Status
Hard-coded credentials make exploitation trivial once discovered. No authentication required to use the credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 10.1.6 and later
Vendor Advisory: https://www.ibm.com/support/pages/node/6114130
Restart Required: Yes
Instructions:
1. Download IBM Spectrum Protect Plus 10.1.6 or later from IBM Fix Central. 2. Follow IBM's upgrade documentation for your deployment type. 3. Apply the update and restart all Spectrum Protect Plus services.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to Spectrum Protect Plus to only trusted administrative networks
Use firewall rules to limit inbound/outbound connections to specific IP ranges
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Spectrum Protect Plus from untrusted networks
- Enable detailed logging and monitoring for authentication attempts and unusual administrative activity
🔍 How to Verify
Check if Vulnerable:
Check the installed version via the Spectrum Protect Plus web interface or administrative console. If version is between 10.1.0 and 10.1.5 inclusive, the system is vulnerable.Check Version:
On the Spectrum Protect Plus server, check the version in the web interface or use the administrative tools specific to your deployment.Verify Fix Applied:
Verify the version is 10.1.6 or later and check that the hard-coded credentials documented in the advisory are no longer present or functional.📡 Detection & Monitoring
Log Indicators:
- Authentication attempts using default/hard-coded credentials
- Unusual administrative actions from unexpected IP addresses
- Failed credential changes or validation errors
Network Indicators:
