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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Oracle OPERA 5 Property Services installation
    Review your installed software inventory or check the application properties within the OPERA administration console to identify if Oracle Hospitality OPERA 5 Property Services is deployed
    Affected if The software is present on the system
  2. Verify the exact version number
    Access the OPERA system information or version details panel (typically found in the administration or system settings area) and confirm the installed version is 5.6
    Affected if The installed version is exactly 5.6 (version match)
  3. Determine if OXI component is configured
    Check the OPERA component configuration or module list to see if the OXI (Opera XML Interface) component is enabled or configured within the Property Services installation
    Affected if The OXI component is enabled or configured in the environment
  4. Assess network accessibility of OXI endpoint
    Identify the network endpoint(s) for the OXI component (typically accessible via HTTP/HTTPS on configured ports) and determine if it is reachable from network locations
    Affected if The OXI component is accessible over HTTP from non-trusted networks
  5. Identify high-privileged accounts with OXI access
    Review user accounts and roles within OPERA that have high privileges and access permissions to the OXI component, particularly accounts with administrative or data access roles
    Affected if High-privileged accounts exist with OXI component access

You are affected if Oracle Hospitality OPERA 5 Property Services version 5.6 is installed and the OXI component is enabled and accessible via HTTP, regardless of account status the vulnerability requires a high-privileged attacker to exploit.
