CVE-2025-36157
📋 TL;DR
This vulnerability allows unauthenticated remote attackers to modify server property files in IBM Jazz Foundation, potentially enabling unauthorized actions like privilege escalation or configuration changes. Affected versions include IBM Jazz Foundation 7.0.2 through 7.0.2 iFix035, 7.0.3 through 7.0.3 iFix018, and 7.1.0 through 7.1.0 iFix004.
💻 Affected Systems
- IBM Jazz Foundation
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary code, steal sensitive data, or disrupt services by modifying critical configuration files.
Likely Case
Unauthorized configuration changes leading to privilege escalation, service disruption, or data exposure through modified server properties.
If Mitigated
Limited impact with proper network segmentation and access controls preventing unauthenticated access to vulnerable endpoints.
🎯 Exploit Status
CVSS 9.8 indicates critical severity with network-based, unauthenticated exploitation possible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply IBM Jazz Foundation 7.0.2 iFix036, 7.0.3 iFix019, or 7.1.0 iFix005
Vendor Advisory: https://www.ibm.com/support/pages/node/7242925
Restart Required: Yes
Instructions:
1. Download appropriate iFix from IBM Fix Central. 2. Backup current installation. 3. Apply iFix following IBM documentation. 4. Restart Jazz services. 5. Verify patch application.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to Jazz Foundation servers to trusted IPs only
iptables -A INPUT -p tcp --dport <jazz_port> -s <trusted_ip> -j ACCEPT
iptables -A INPUT -p tcp --dport <jazz_port> -j DROP
Reverse Proxy Configuration
allPlace Jazz Foundation behind a reverse proxy with authentication
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Jazz Foundation servers
- Deploy web application firewall with rules to block unauthorized property file modifications
🔍 How to Verify
Check if Vulnerable:
Check Jazz Foundation version via administrative console or version.txt fileCheck Version:
Check <JAZZ_HOME>/version.txt or use Jazz administrative consoleVerify Fix Applied:
Verify iFix installation through Jazz administrative interface or check version files📡 Detection & Monitoring
