CVE-2020-4613
📋 TL;DR
IBM Data Risk Manager 2.0.6 uses weak cryptographic algorithms that could allow attackers to decrypt sensitive information. This affects organizations using IBM iDNA 2.0.6 for data risk management. The vulnerability stems from inadequate cryptographic protection of sensitive data.
💻 Affected Systems
- IBM Data Risk Manager (iDNA)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers decrypt and exfiltrate highly sensitive risk management data, potentially including confidential business intelligence, compliance information, and security assessment data.
Likely Case
Attackers with access to encrypted data can decrypt sensitive information, compromising data confidentiality and potentially enabling further attacks.
If Mitigated
With proper network segmentation and access controls, impact is limited to authorized users who might abuse weak cryptography.
🎯 Exploit Status
Exploitation requires access to encrypted data and cryptographic analysis capabilities. No public exploits have been documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.0.6.1 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/6335281
Restart Required: Yes
Instructions:
1. Download the fix from IBM Fix Central. 2. Apply the patch following IBM's installation guide. 3. Restart the IBM Data Risk Manager service. 4. Verify the update by checking the version number.
