CVE-2025-15395
📋 TL;DR
This CVE describes an access control vulnerability in IBM Jazz Foundation that allows authenticated users to perform actions or view data beyond their authorized permissions. The vulnerability affects IBM Jazz Foundation versions 7.0.3 through 7.0.3 iFix019 and 7.1.0 through 7.1.0 iFix005. This is an authorization bypass issue where users can exceed their intended privileges.
💻 Affected Systems
- IBM Jazz Foundation
⚠️ Risk & Real-World Impact
Worst Case
An authenticated user could gain administrative privileges, modify critical system configurations, access sensitive data, or disrupt service operations.
Likely Case
Users could access restricted data or perform unauthorized actions within their authenticated session, potentially leading to data exposure or unauthorized changes.
If Mitigated
With proper network segmentation and least privilege access controls, impact would be limited to specific application functions rather than full system compromise.
🎯 Exploit Status
Exploitation requires authenticated access but the specific bypass mechanism is not publicly documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply iFix020 for 7.0.3 or iFix006 for 7.1.0
Vendor Advisory: https://www.ibm.com/support/pages/node/7258304
Restart Required: Yes
Instructions:
1. Download the appropriate iFix from IBM Fix Central. 2. Stop the Jazz application server. 3. Apply the iFix according to IBM documentation. 4. Restart the application server. 5. Verify the fix by checking version information.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to Jazz Foundation to only trusted users and networks
Enhanced Monitoring
allImplement enhanced logging and monitoring for privilege escalation attempts
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Jazz Foundation from critical systems
- Enforce principle of least privilege for all user accounts and conduct regular access reviews
🔍 How to Verify
Check if Vulnerable:
Check the Jazz Foundation version via the application's About page or by examining installation directories for version files.Check Version:
Check the Jazz Team Server version via the web interface or examine the server logs for version information.Verify Fix Applied:
Verify the installed version is beyond the vulnerable ranges: for 7.0.3, ensure iFix020 or later is applied; for 7.1.0, ensure iFix006 or later is applied.📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns to restricted functions
- Failed authorization attempts followed by successful access
- User performing actions outside their normal role
Network Indicators:
- Unusual API calls to administrative endpoints from non-admin users
- Access to restricted data endpoints
