Recommended fix Moderate confidence

Oracle Mobile Field Service 12.1.4 or later; 12.2.11 or later (apply October 2021 CPU patch for your release)

  1. 1. Review the October 2021 Critical Patch Update (CPU) at https://www.oracle.com/security-alerts/cpuoct2021.html for the specific patch numbers for Oracle Mobile Field Service
  2. 2. Identify the appropriate patch for your current Oracle E-Business Suite release (12.1.x or 12.2.x)
  3. 3. Download and apply the relevant security patch from Oracle Global Support
  4. 4. After applying the patch, verify the Admin UI component is updated by checking the system version
  5. 5. Test that low-privileged user accounts can no longer perform unauthorized creation, deletion, or modification operations in the Admin UI
Caveat Oracle CPU patches are cumulative; applying the October 2021 CPU may include other security fixes - review release notes for compatibility with customizations
