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. Identify Oracle Hospitality OPERA 5 Property Services installation
    Look for OPERA 5 Property Services processes or installed services on the system. Check Windows Services, Linux service listings, or application inventory for 'Oracle Hospitality OPERA 5' or 'OPERA Property Services'.
    Affected if The software is present on the system and matches the affected product family
  2. Determine the installed version
    Check the installed version of Oracle Hospitality OPERA 5 Property Services. This is typically found in the application installation directory, About dialog, version info file, or product registration. Compare the version number to 5.5 or 5.6.
    Affected if The installed version is exactly 5.5 or exactly 5.6
  3. Verify the logging component is accessible
    The vulnerability is in the logging component. Determine if this component accepts HTTP network connections. Check the application configuration files or service endpoints for HTTP listeners related to logging functionality.
    Affected if The logging component is exposed and accessible via HTTP network access
  4. Assess network exposure
    Review network configuration, firewall rules, or load balancer settings to determine if the OPERA 5 Property Services HTTP interface is accessible from untrusted networks. Check if external network access is permitted to the logging component port/endpoint.
    Affected if The HTTP interface is accessible from untrusted or external network segments

You are affected if Oracle Hospitality OPERA 5 Property Services version 5.5 or 5.6 is installed with its logging component exposed via HTTP to untrusted networks, allowing a high-privileged attacker to potentially interact with the system.
