CVE-2019-4675
📋 TL;DR
IBM Security Identity Manager 7.0.1 contains hard-coded credentials that could allow attackers to authenticate to the system, communicate with external components, or decrypt internal data without proper authorization. This affects all deployments of IBM Security Identity Manager 7.0.1 that haven't been patched. The vulnerability is particularly dangerous because it involves built-in authentication mechanisms.
💻 Affected Systems
- IBM Security Identity Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the identity management system allowing attackers to create/modify/delete user accounts, escalate privileges, access sensitive identity data, and potentially pivot to other systems.
Likely Case
Unauthorized access to the identity management system leading to privilege escalation, user account manipulation, and exposure of sensitive identity information.
If Mitigated
Limited impact if system is isolated behind strong network controls, but hard-coded credentials still represent a significant security weakness.
🎯 Exploit Status
Hard-coded credentials typically require minimal technical skill to exploit once discovered. The specific credentials would need to be identified through reverse engineering or information disclosure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply interim fix or upgrade as specified in IBM advisory
Vendor Advisory: https://www.ibm.com/support/pages/node/1288714
Restart Required: Yes
Instructions:
1. Review IBM advisory at the provided URL. 2. Apply the recommended interim fix or upgrade to a patched version. 3. Restart the IBM Security Identity Manager service. 4. Verify the fix has been applied successfully.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to IBM Security Identity Manager to only necessary systems and users
Configure firewall rules to limit inbound/outbound connections
Credential Rotation
allChange any known hard-coded credentials if possible
Follow IBM documentation for credential management procedures
🧯 If You Can't Patch
- Isolate the system in a dedicated network segment with strict access controls
- Implement additional authentication layers and monitor all access attempts to the system
🔍 How to Verify
Check if Vulnerable:
Check if running IBM Security Identity Manager version 7.0.1. Review configuration files for hard-coded credentials.
Check Version:
Check IBM Security Identity Manager administration console or installation logs for version information
Verify Fix Applied:
Verify the applied patch version matches IBM's recommendation. Test authentication with previously known hard-coded credentials to ensure they no longer work.
📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts with unusual patterns
- Successful authentication from unexpected sources
- Configuration file access/modification
Network Indicators:
- Unusual outbound connections from the identity manager system
- Authentication traffic from unexpected IP addresses
