Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the Oracle Hospitality OPERA 5 Property Services component of Oracle Hospitality Applications (subcomponent: OPERA Printing). Supported versions that are affected are 5.4.0.x, 5.4.1.x, 5.4.2.x, 5.4.3.x, 5.5.0.x and 5.5.1.x. Easily "exploitable" vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hospitality OPERA 5 Property Services. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hospitality OPERA 5 Property Services, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Hospitality OPERA 5 Property Services accessible data as well as unauthorized read access to a subset of Oracle Hospitality OPERA 5 Property Services accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Unauthenticated network attacker can exploit the OPERA Printing subcomponent in Oracle Hospitality OPERA 5 via HTTP to achieve unauthorized read and partial data modification (insert/update/delete) on accessible data. Exploitation requires human interaction (e.g., tricking a user to click a malicious link). Scope changed indicates impact extends beyond the vulnerable subcomponent.

MitigationApply Oracle's relevant security patch from the CPU. If unavailable, restrict network access to the OPERA HTTP interface and implement additional input validation/authentication layers for the printing service.

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 Hospitality OPERA 5 is installed
    Check for OPERA 5 installation directories, services, or consult your Oracle licensing/inventory for property management systems. Look for 'OPERA' or 'Oracle Hospitality' in installed software listings.
    Affected if OPERA 5 Property Services is not installed on the system
  2. Identify installed OPERA version
    Use Oracle's standard version identification methods for OPERA 5, such as checking the application About/Version dialog, consulting the system administrator, or reviewing Oracle support documentation for version location.
    Affected if The installed version is 5.4.0, 5.4.1, 5.4.2, 5.4.3, 5.5.0, or 5.5.1
  3. Determine if OPERA HTTP interface is enabled
    Check the OPERA configuration settings or web server configuration for the property services application. Verify whether the HTTP/HTTPS listener is active for the OPERA Printing subcomponent.
    Affected if The HTTP interface for the printing service is enabled and listening
  4. Assess network accessibility of the printing service
    Review network firewall rules, reverse proxy configurations, and access control lists to determine if the OPERA HTTP port (typically 8080 or 443 for Oracle OPERA) is reachable from untrusted networks.
    Affected if The OPERA HTTP interface is exposed to network segments accessible to unauthenticated attackers
  5. Verify human interaction requirement
    Review the application topology and consider whether end users would be likely to access the HTTP interface through crafted links, particularly in scenarios where phishing or social engineering could be attempted.
    Affected if Users have network access to the OPERA HTTP interface and could be targeted with malicious links

A system is affected if Oracle Hospitality OPERA 5 Property Services versions 5.4.0 through 5.5.1 are installed with the OPERA Printing subcomponent accessible via HTTP to potentially vulnerable users.
