CVE-2021-29694

7.5 HIGH

📋 TL;DR

IBM Spectrum Protect Plus versions 10.1.0 through 10.1.7 use weak cryptographic algorithms, allowing attackers to decrypt sensitive information. This affects organizations using these versions for data backup and recovery. The vulnerability exposes highly sensitive data protected by the software.

💻 Affected Systems

Products:
  • IBM Spectrum Protect Plus
Versions: 10.1.0 through 10.1.7
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments using affected versions are vulnerable regardless of configuration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers decrypt and exfiltrate sensitive backup data including credentials, financial information, and intellectual property, leading to data breaches and regulatory violations.

🟠

Likely Case

Attackers with network access decrypt specific sensitive information from backups, potentially compromising business-critical data.

🟢

If Mitigated

With proper network segmentation and access controls, only authorized users can access backup systems, limiting exposure.

🌐 Internet-Facing: HIGH if backup systems are internet-accessible, as attackers could remotely exploit weak cryptography.
🏢 Internal Only: MEDIUM as internal attackers or compromised accounts could exploit the vulnerability to access sensitive backup data.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires access to encrypted data and cryptographic analysis capabilities.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 10.1.8 or later

Vendor Advisory: https://www.ibm.com/support/pages/node/6445735

Restart Required: Yes

Instructions:

1. Download IBM Spectrum Protect Plus 10.1.8 or later from IBM Fix Central. 2. Follow IBM's upgrade documentation for your deployment type. 3. Restart all Spectrum Protect Plus services after upgrade.

🔧 Temporary Workarounds

Network Segmentation

all

Restrict network access to Spectrum Protect Plus systems to only authorized management networks.

Access Control Hardening

all

Implement strict access controls and monitoring for backup data access.

🧯 If You Can't Patch

  • Isolate Spectrum Protect Plus systems from untrusted networks and implement strict access controls.
  • Monitor for unusual access patterns to backup data and implement additional encryption layers for sensitive data.

🔍 How to Verify

Check if Vulnerable:

Check the Spectrum Protect Plus version via the web interface or command line. Versions 10.1.0 through 10.1.7 are vulnerable.

Check Version:

On Spectrum Protect Plus server: 'java -jar /opt/IBM/SPP/version.jar' or check web interface under Help > About

Verify Fix Applied:

Verify the version is 10.1.8 or later and confirm cryptographic algorithms have been updated per IBM documentation.

📡 Detection & Monitoring

Log Indicators:

  • Unusual access patterns to backup data
  • Failed decryption attempts
  • Unauthorized access to cryptographic functions

Network Indicators:

  • Unexpected network traffic to backup systems
  • Traffic patterns suggesting data exfiltration

SIEM Query:

source="spp_logs" AND (event="decryption_failure" OR event="unauthorized_access")
