Siemens Opcenter Quality

CVSS 7.1 HIGH

Remediations

  • The SmartClient should be operated in a secured network and context only
  • Remove all tools giving possibility to call SOAP-services outside from the SmartClient
  • The hardening instructions mentioned in the products security concept should be followed
  • Update to V2506 or later version
  • Harden LDAP-interface secure protocols by enabling the SSL-flag on configuration and a proper setup of your TLS-configuration
  • All the users (including in LDAP) should be given the least privileges required
  • Limit the permission to access those fields using the least privilege strategy
  • Do not use original table structures and accounts for reporting. Create your own reporting accounts which have access via synonyms forwarding on views representing access to result-sets the user may use for evaluation
  • Use DB-tools to limit load on productive systems for reporting accounts or use offline systems for reporting
  • Harden your IIS
  • Prevent any scanning of structures and configurations
  • Limit the information to prevent to the end-user based on the need-to-know-principle to the minimum possible information
  • Hardening of the solution, including the OS and IIS, is required, with specific measures such as hiding the IIS version to enhance security
  • Users should not have the possibility to scan folders and extensions of files allowed to open should be limited to the required one
  • Disable all protocols (SSL v2/v3, TLS 1.0, TLS 1.1) the solution should not use.
  • Ensure, TLS 1.2 is enabled if you plan to use TLS 1.2.
  • Follow the instructions of the security concept of Opcenter Quality and vendors.
