CVE-2020-4854
📋 TL;DR
IBM Spectrum Protect Plus versions 10.1.0 through 10.1.6 contain hard-coded credentials used for authentication and encryption. This allows attackers to gain unauthorized access to the system and potentially compromise sensitive backup data. Organizations using these vulnerable versions are affected.
💻 Affected Systems
- IBM Spectrum Protect Plus
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to access, modify, or delete all backup data, potentially leading to data loss, ransomware deployment, or credential theft from backup repositories.
Likely Case
Unauthorized access to backup data, potential data exfiltration, and privilege escalation within the Spectrum Protect Plus environment.
If Mitigated
Limited impact if system is isolated, but still vulnerable to insider threats or compromised accounts with access to the system.
🎯 Exploit Status
Hard-coded credentials are trivial to exploit once discovered. No authentication required to use these credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 10.1.7 and later
Vendor Advisory: https://www.ibm.com/support/pages/node/6367823
Restart Required: Yes
Instructions:
1. Download IBM Spectrum Protect Plus 10.1.7 or later from IBM Fix Central. 2. Backup current configuration. 3. Apply the update following IBM's installation guide. 4. Restart all Spectrum Protect Plus services.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to Spectrum Protect Plus servers to only trusted administrative networks
Credential Rotation
allManually change any credentials that may be derived from hard-coded values (requires IBM support guidance)
🧯 If You Can't Patch
- Isolate Spectrum Protect Plus servers from all non-essential networks using firewall rules
- Implement strict network segmentation and monitor all access to Spectrum Protect Plus systems
🔍 How to Verify
Check if Vulnerable:
Check IBM Spectrum Protect Plus version via administrative console or command: 'java -jar /opt/tivoli/tsm/isc/isc.jar version' on Linux systemsCheck Version:
java -jar /opt/tivoli/tsm/isc/isc.jar versionVerify Fix Applied:
Verify version is 10.1.7 or later using same version check command📡 Detection & Monitoring
Log Indicators:
- Unauthorized authentication attempts using default/hard-coded credentials
- Unusual access patterns to backup data
- Failed credential rotation attempts
Network Indicators:
- Unexpected connections to Spectrum Protect Plus ports (9080, 9081, 9443)
- Traffic from unauthorized IP addresses to backup servers
