CVE-2022-31619
📋 TL;DR
Teamcenter Java EE Server Manager HTML Adaptor contains hardcoded default credentials. Attackers with access to the application can exploit these credentials to potentially achieve remote code execution with elevated permissions. Affects Teamcenter V12.4 through V14.0 in specific vulnerable versions.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via remote code execution with administrative privileges, leading to data theft, system manipulation, or ransomware deployment.
Likely Case
Unauthorized access to sensitive Teamcenter data and configuration, privilege escalation within the application environment.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external/internal attackers from reaching the vulnerable component.
🎯 Exploit Status
Exploitation requires network access to the vulnerable component but no authentication due to hardcoded credentials. Attack path is straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: V12.4.0.13, V13.0.0.9, V13.1.0.9, V13.2.0.9, V13.3.0.3, V14.0.0.2 or later
Vendor Advisory: https://cert-portal.siemens.com/productcert/pdf/ssa-220589.pdf
Restart Required: Yes
Instructions:
1. Download the appropriate patch from Siemens support portal. 2. Apply patch according to Siemens installation documentation. 3. Restart Teamcenter services. 4. Verify the patch version.
🔧 Temporary Workarounds
Network Access Restriction
allBlock network access to the Java EE Server Manager HTML Adaptor port (default 8080) from untrusted networks.
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="0.0.0.0/0" port protocol="tcp" port="8080" reject'
netsh advfirewall firewall add rule name="Block Teamcenter Manager" dir=in action=block protocol=TCP localport=8080
Credential Change
allChange default credentials if possible through Teamcenter configuration (though patch is preferred as hardcoded credentials may persist).
🧯 If You Can't Patch
- Isolate Teamcenter servers behind firewalls with strict network segmentation
- Implement application-level monitoring for unauthorized access attempts to the Java EE Server Manager
🔍 How to Verify
Check if Vulnerable:
Check Teamcenter version via administration console or version files. Compare against affected version ranges.Check Version:
Check Teamcenter installation directory for version files or use Teamcenter administration tools to display version.Verify Fix Applied:
Verify installed version matches or exceeds patched versions: V12.4.0.13, V13.0.0.9, V13.1.0.9, V13.2.0.9, V13.3.0.3, or V14.0.0.2.📡 Detection & Monitoring
Log Indicators:
- Unauthorized authentication attempts to Java EE Server Manager
- Unusual process execution from Teamcenter services
- Access logs showing connections to manager port from unexpected sources
Network Indicators:
- Traffic to Teamcenter Java EE Server Manager port (default 8080) from unauthorized IPs
- Unusual outbound connections from Teamcenter servers
SIEM Query:
source="teamcenter.log" AND ("authentication failed" OR "unauthorized access") OR destination_port=8080 AND NOT source_ip IN [allowed_ips]
