CVE-2020-4611
📋 TL;DR
CVE-2020-4611 is an authentication bypass vulnerability in IBM Data Risk Manager (iDNA) that allows authenticated users to perform administrative actions without proper authorization. This affects organizations running vulnerable versions of IBM Data Risk Manager 2.0.6. The vulnerability enables privilege escalation from regular user accounts to administrative privileges.
💻 Affected Systems
- IBM Data Risk Manager (iDNA)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker with any authenticated account could gain full administrative control over the IBM Data Risk Manager system, potentially accessing sensitive risk data, modifying configurations, or disrupting operations.
Likely Case
Malicious insiders or compromised user accounts could escalate privileges to perform unauthorized administrative actions, potentially accessing confidential risk assessment data or modifying security controls.
If Mitigated
With proper network segmentation and access controls, the impact would be limited to the IBM Data Risk Manager system itself, though administrative compromise could still lead to data exposure.
🎯 Exploit Status
Requires authenticated access but allows privilege escalation to admin. No public exploit code available.
🛠️ 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

🔧 Temporary Workarounds
Restrict Access
allLimit network access to IBM Data Risk Manager to only trusted users and networks
Monitor User Activity
allImplement enhanced monitoring of user actions and privilege escalation attempts
🧯 If You Can't Patch
- Isolate the IBM Data Risk Manager system from other critical systems using network segmentation
- Implement strict access controls and monitor all administrative actions for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check the IBM Data Risk Manager version via the web interface or configuration files. If version is 2.0.6, the system is vulnerable.Check Version:
Check the web interface or consult IBM Data Risk Manager documentation for version checking commands specific to your installation.Verify Fix Applied:
Verify the version is updated to 2.0.6.1 or later and test that authenticated users cannot perform administrative actions.📡 Detection & Monitoring
