Summary
TRUMPF: Multiple products prone to WIBU CodeMeter vulnerabilities
Notes
Summary: A number of TRUMPF CAD/CAM software tools use the CodeMeter Runtime application from WIBU-SYSTEMS AG to manage licences. This application contains a number of vulnerabilities, which enable an attacker to prevent normal operation of CodeMeter, resulting in a Denial-of-Service and potentially execute arbitrary code.
Impact: The stated TRUMPF CAD/CAM products are supplied with the WIBU CodeMeter Runtime Software in versions that are known to contain a number of vulnerabilities. We can not confirm at this time whether the use of vulnerable CodeMeter exposes our products to the risks described in the CVEs mentioned above. Nevertheless, we are working to replace the vulnerable versions of CodeMeter with available fixed versions.
Mitigation: - Use the updated versions of the TRUMPF CAD/CAM products that will be available via your service channel shortly. - Until then, reduce internet usage on workstations with TRUMPF CAD/CAM products to a minimum.
CVE-2020-14509

Multiple memory corruption vulnerabilities exist in CodeMeter (All versions prior to 7.10) where the packet parser mechanism does not verify length fields. An attacker could send specially crafted packets to exploit these vulnerabilities.

9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-805 - Buffer Access with Incorrect Length Value
Mitigation - Use the updated versions of the TRUMPF CAD/CAM products that will be available via your service channel shortly. - Until then, reduce internet usage on workstations with TRUMPF CAD/CAM products to a minimum.
CVE-2020-14517

Protocol encryption can be easily broken for CodeMeter (All versions prior to 6.90 are affected, including Version 6.90 or newer only if CodeMeter Runtime is running as server) and the server accepts external connections, which may allow an attacker to remotely communicate with the CodeMeter API.

9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-326 - Inadequate Encryption Strength
Mitigation - Use the updated versions of the TRUMPF CAD/CAM products that will be available via your service channel shortly. - Until then, reduce internet usage on workstations with TRUMPF CAD/CAM products to a minimum.
CVE-2020-16233

An attacker could send a specially crafted packet that could have CodeMeter (All versions prior to 7.10) send back packets containing data from the heap.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
CWE-404 - Improper Resource Shutdown or Release
Mitigation - Use the updated versions of the TRUMPF CAD/CAM products that will be available via your service channel shortly. - Until then, reduce internet usage on workstations with TRUMPF CAD/CAM products to a minimum.
CVE-2020-14519

This vulnerability allows an attacker to use the internal WebSockets API for CodeMeter (All versions prior to 7.00 are affected, including Version 7.0 or newer with the affected WebSockets API still enabled. This is especially relevant for systems or devices where a web browser is used to access a web server) via a specifically crafted Java Script payload, which may allow alteration or creation of license files for when combined with CVE-2020-14515.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
CWE-346 - Origin Validation Error
Mitigation - Use the updated versions of the TRUMPF CAD/CAM products that will be available via your service channel shortly. - Until then, reduce internet usage on workstations with TRUMPF CAD/CAM products to a minimum.
CVE-2020-14513

CodeMeter (All versions prior to 6.81) and the software using it may crash while processing a specifically crafted license file due to unverified length fields.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-20 - Improper Input Validation
Mitigation - Use the updated versions of the TRUMPF CAD/CAM products that will be available via your service channel shortly. - Until then, reduce internet usage on workstations with TRUMPF CAD/CAM products to a minimum.
CVE-2020-14515

CodeMeter (All versions prior to 6.90 when using CmActLicense update files with CmActLicense Firm Code) has an issue in the license-file signature checking mechanism, which allows attackers to build arbitrary license files, including forging a valid license file as if it were a valid license file of an existing vendor. Only CmActLicense update files with CmActLicense Firm Code are affected.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
CWE-347 - Improper Verification of Cryptographic Signature
Mitigation - Use the updated versions of the TRUMPF CAD/CAM products that will be available via your service channel shortly. - Until then, reduce internet usage on workstations with TRUMPF CAD/CAM products to a minimum.
