CVE-2025-14687
📋 TL;DR
IBM Db2 Intelligence Center versions 1.1.0 through 1.1.2 contain a client-side enforcement vulnerability where security mechanisms that should be enforced server-side are instead enforced on the client. This allows authenticated users to bypass intended restrictions and perform unauthorized actions. Only authenticated users with existing access to the system can exploit this vulnerability.

- IBM Db2 Intelligence Center
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated malicious insider could escalate privileges, access sensitive data they shouldn't have access to, modify critical configurations, or perform administrative functions beyond their authorized role.
Likely Case
Authenticated users could bypass intended access controls to view or modify data they shouldn't have access to, potentially leading to data exposure or unauthorized changes.
If Mitigated
With proper network segmentation, least privilege access controls, and monitoring, the impact would be limited to authorized users performing actions slightly beyond their intended scope.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of how to bypass client-side controls, which could involve modifying client-side code or using proxy tools to manipulate requests.

🔍 How to Verify
Check if Vulnerable:
Check your Db2 Intelligence Center version. If it's 1.1.0, 1.1.1, or 1.1.2, you are vulnerable.Check Version:
Consult IBM Db2 Intelligence Center documentation for version checking commands specific to your installationVerify Fix Applied:
After applying the fix, verify the version has been updated and test that client-side modifications no longer bypass intended security controls.📡 Detection & Monitoring
Log Indicators:
- Unusual user activity patterns
- Access to resources beyond normal user permissions
- Failed authorization attempts followed by successful access
Network Indicators:
- Unusual API calls or requests that bypass normal client workflows
