CVSS 3.1 Base Score 6.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/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 confidence

Oracle Clinical Remote Data Capture version 5.4.0.2 contains a vulnerability in the Forms component that allows a low-privileged attacker with network access via HTTP to gain unauthorized access to critical or all data in the system. The vulnerability has high confidentiality impact with no integrity or availability impact, indicating a data exposure/authorization flaw.

MitigationApply the Oracle Critical Patch Update that addresses CVE-2023-21993, or upgrade to a patched version of Oracle Clinical Remote Data Capture if available. If patches are delayed, review and restrict user permissions in the Forms component and implement additional network-level access controls.

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 Oracle Clinical Remote Data Capture version
    Check the application version through Oracle Clinical's built-in version information page, typically accessible via the About or Version link in the application footer, or query the Oracle Clinical database version tables if you have administrative access
    Affected if The installed version is exactly 5.4.0.2
  2. Verify Forms component is deployed and accessible
    Check if the Forms component is deployed on your Oracle Clinical application server by reviewing the application configuration files (such as formsweb.cfg for Oracle Forms) or accessing the Forms servlet URL endpoint typically at /forms/frmservlet or /forms90/frmservlet
    Affected if The Forms component is exposed and accessible via HTTP/HTTPS network access
  3. Confirm Forms component is accessible over the network
    Test network connectivity to the Forms component URL endpoints (such as /forms/frmservlet or the Oracle Clinical Forms listener port) using curl or a browser from an external or untrusted network segment
    Affected if The Forms component is reachable from network locations where low-privileged users operate
  4. Review Forms component user permissions and authorization configuration
    Examine the Oracle Clinical user roles and permissions assigned to the Forms component through the application administration interface, specifically checking whether low-privileged users have access to sensitive data fields or unauthorized record sets within Forms
    Affected if Low-privileged users have permissions that allow access to critical or all data through the Forms interface
  5. Examine application access logs for anomalous Forms data access
    Review Oracle HTTP Server access logs, Oracle Forms runtime logs, and Oracle Clinical application logs for patterns where low-privileged users accessed records or data fields outside their expected scope
    Affected if Logs show low-privileged users accessing data beyond their authorized scope

Your environment is affected if you are running Oracle Clinical Remote Data Capture version 5.4.0.2 with the Forms component accessible over the network and low-privileged users can access data beyond their authorized scope.
