affected by CVE-2019-18340
Currently no fix is planned
  • Apply ACL/firewall configuration on the CCS server to ensure that only legitimate systems are able to access the configured CCS server ports. Harden the CCS server accordingly to prevent unauthorized access. Consider to apply encryption and authentication on the network (e.g., via TLS on application level or via IPSec on host level).
  • CVE-2019-18340: Harden the CCS server to prevent local access by unauthorized users
  • CVE-2019-19290, CVE-2019-19293, CVE-2019-19294: Disable the web interface of CCS if not used. Alternatively, restrict access from localhost only, or only to trusted hosts of CCS administrators. Enable TLS for the web interface of CCS.

Un-/Collapse All

The vulnerability classification has been performed by using the CVSS scoring system in version 3.1 (CVSS v3.1) ( The CVSS environmental score is specific to the customer’s environment and will impact the overall CVSS score. The environmental score should therefore be individually defined by the customer to accomplish final scoring.

An additional classification has been performed using the CWE classification, a community-developed list of common software security weaknesses. This serves as a common language and as a baseline for weakness identification, mitigation, and prevention efforts. A detailed list of CWE classes can be found at:
