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

Oracle REST Data Services contains an information disclosure vulnerability in the General component affecting versions 24.2.0 through 26.1.0. An unauthenticated attacker with network access via HTTPS can read a subset of accessible data due to improper access controls.

MitigationApply the appropriate Oracle patch for this vulnerability when available, or upgrade to a patched version of Oracle REST Data Services. Additionally, restrict network access to the ORDS endpoints to minimize exposure.

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 installed ORDS version
    Check the ORDS installation by looking for the ords.war file version, or query the /ords/ path with /ords/_/health endpoint, or check the ORDS logs for the version string during startup
    Affected if The installed version is between 24.2.0 and 26.1.0 inclusive
  2. Confirm ORDS HTTP/HTTPS listener is active
    Verify the Oracle REST Data Services web listener is running and accessible on its configured port (typically 8080, 8443, or 443) by making a test request to the root endpoint
    Affected if ORDS is running and responding to HTTP/HTTPS requests on any network interface
  3. Verify network accessibility of ORDS endpoints
    Check if the ORDS server is bound to a public or unresticted IP address, or if firewall rules allow external access to the ORDS port. Use 'netstat -tlnp' or equivalent to see binding address
    Affected if ORDS is bound to 0.0.0.0 or an IP accessible from untrusted networks, allowing unauthenticated access
  4. Test unauthenticated endpoint access
    Send an HTTP request to the ORDS base URL without providing any authentication credentials and observe whether the service responds with data or exposes protected resources
    Affected if The service responds to unauthenticated requests and returns data that should require authentication

A user is affected if their ORDS installation version is 24.2.0 through 26.1.0 and the service is accessible over the network without authentication.
