CVE-2022-34661
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been identified in Teamcenter V12.4 (All versions < V12.4.0.15), Teamcenter V13.0 (All versions < V13.0.0.10), Teamcenter V13.1 (All versions < V13.1.0.10), Teamcenter V13.2 (All versions < V13.2.0.9), Teamcenter V13.3 (All versions < V13.3.0.5), Teamcenter V14.0 (All versions < V14.0.0.2). File Server Cache service in Teamcenter is vulnerable to denial of service by entering infinite loops and using up CPU cycles. This could allow an attacker to cause denial of service condition.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe File Server Cache service in multiple Teamcenter versions contains a vulnerability allowing attackers to trigger infinite loops, consuming CPU cycles and causing denial of service. This affects Teamcenter V12.4 through V14.0 in specific version ranges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Teamcenter installation existsLocate the Teamcenter installation directory, typically under %TC_ROOT% environment variable or common paths like C:\Siemens\Teamcenter or /opt/siemens/teamcenter. Check for the presence of core Teamcenter binaries and the 'tccs' (Teamcenter Cache Service) directory.Affected if Teamcenter software is not found on the system
-
Identify installed Teamcenter versionCheck the version file in the Teamcenter installation directory. Common locations: <TC_ROOT>/version.txt, <TC_ROOT>/bin/version.info, or run the Teamcenter version command: tcserver -version or lmstat -c <license_file> -a. Extract the full version number including patch level (for example, 13.0.0.9).Affected if Unable to determine the installed version number
-
Confirm File Server Cache service is enabledThe vulnerability resides in the File Server Cache (FSC) service. Check if this service is configured and running. On Windows, verify the 'Teamcenter File Server Cache' service status via Services.msc. On Linux, check for processes like 'fsc' or 'tccs' via ps -ef | grep -i cache. Also verify the FSC port is listening (default ports 8085, 8086).Affected if File Server Cache service is not installed or not configured
-
Compare version against affected rangesMatch your installed version against: 12.4.x where x < 15; 13.0.x where x < 10; 13.1.x where x < 10; 13.2.x where x < 9; 13.3.x where x < 5; 14.0.x where x < 2. For example, version 13.0.0.9 is vulnerable (9 < 10), while 13.0.0.10 is patched.Affected if Installed version falls within any of these ranges: >= 12.4.0.0 and < 12.4.0.15, OR >= 13.0.0.0 and < 13.0.0.10, OR >= 13.1.0.0 and < 13.1.0.10, OR >= 13.2.0.0 and < 13.2.0.9, OR >= 13.3.0.0 and < 13.3.0.5, OR >= 14.0.0.0 and < 14.0.0.2
Your environment is affected if Siemens Teamcenter is installed with the File Server Cache service enabled and the installed version falls within any of the vulnerable version ranges listed above.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped12.4.0.1513.0.0.1013.1.0.10
Apply the vendor-supplied patches (V12.4.0.15, V13.0.0.10, V13.1.0.10, V13.2.0.9, V13.3.0.5, V14.0.0.2 or later) to the affected Teamcenter installations to remediate the infinite loop vulnerability in the File Server Cache service.
Upgrade to V12.4.0.15 (for 12.4 line), V13.0.0.10 (for 13.0 line), V13.1.0.10 (for 13.1 line), V13.2.0.9 (for 13.2 line), V13.3.0.5 (for 13.3 line), or V14.0.0.2 (for 14.0 line)
- 1. Identify the currently installed Teamcenter major version (12.4, 13.0, 13.1, 13.2, 13.3, or 14.0)
- 2. Download the corresponding fixed version from Siemens support portal: V12.4.0.15, V13.0.0.10, V13.1.0.10, V13.2.0.9, V13.3.0.5, or V14.0.0.2
- 3. Schedule a maintenance window and backup the existing Teamcenter environment
- 4. Apply the upgrade following Siemens standard upgrade procedures
- 5. Verify the File Server Cache service starts successfully
- 6. Test that normal Teamcenter operations function correctly
