CVSS 3.1 Base Score 6.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/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 · high confidenceVulnerability in the Logging component of Oracle Hospitality OPERA 5 Property Services (versions 5.5, 5.6) allows a high-privileged attacker with network access via HTTP to perform unauthorized creation, deletion, or modification of critical data, as well as unauthorized access to sensitive or complete data sets. The flaw likely involves improper authorization or input validation within the logging functionality.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed OPERA 5 Property Services versionLocate the version information for Oracle Hospitality OPERA 5 Property Services in the system inventory, about screen, or version diagnostic tool used in your deploymentAffected if The installed version is exactly 5.5 or 5.6
-
Confirm affected version matches CVECompare your identified version against the affected ranges: 5.5 and 5.6 onlyAffected if The version is exactly 5.5 or 5.6 (not higher or lower)
-
Verify Logging component is present and enabledCheck the Oracle OPERA 5 Property Services configuration to determine if the Logging component is installed and operationalAffected if The Logging component exists and is enabled in the installation
-
Check network accessibility of HTTP-based logging endpointsDetermine whether the logging functionality is accessible over HTTP/HTTPS network connections from untrusted networksAffected if The logging endpoints are reachable via network (HTTP) from outside trusted segments
-
Assess high-privileged account exposureReview which accounts in OPERA 5 Property Services hold high privileges that could be used to exploit the logging functionality per the CVE descriptionAffected if High-privileged accounts exist that could leverage this vulnerability
Your environment is affected if the installed version is exactly 5.5 or 5.6 and the Logging component is network-accessible to high-privileged users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Oracle's available patches for CVE-2020-14877 to the OPERA 5 Property Services installation. If patches are unavailable, restrict network access to the logging endpoints and ensure high-privileged accounts follow least-privilege principles.
