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

Unauthenticated HTTP vulnerability in Oracle CRM Gateway for Mobile Devices (Setup of Mobile Applications) allows remote attackers to gain unauthorized access to critical data. The vulnerability is easily exploitable over the network with no user interaction required, and while scoped to this component, attacks may impact additional products in the Oracle E-Business Suite.

MitigationApply the applicable Oracle Critical Patch Update for CVE-2020-2838. If immediate patching is not feasible, restrict network access to the Oracle CRM Gateway for Mobile Devices HTTP endpoints (e.g., via firewall or web application firewall) to prevent unauthenticated external access.

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 CRM Gateway for Mobile Devices is installed
    Locate and identify the Oracle CRM Gateway for Mobile Devices component in your environment using Oracle inventory tools, application listings, or system documentation
    Affected if The component is present in the environment
  2. Determine the installed version
    Use Oracle application administration tools, check the Oracle E-Business Suite version information, or query the component directly to identify the exact version number
    Affected if The installed version is 12.1.1, 12.1.2, or 12.1.3 (falls within >=12.1.1 and <=12.1.3)
  3. Verify the HTTP service is accessible
    Attempt to access the HTTP endpoints for the Mobile Applications setup component using a web browser or HTTP client from an internal or external network location
    Affected if The HTTP service is reachable and responds to requests without authentication
  4. Confirm lack of authentication on vulnerable endpoints
    Send HTTP requests to the CRM Gateway for Mobile Devices endpoints without providing credentials and observe if access to critical data is granted
    Affected if Unauthenticated requests successfully retrieve sensitive data or perform unauthorized actions

If Oracle CRM Gateway for Mobile Devices version 12.1.1 through 12.1.3 is installed and its HTTP interface is exposed without proper authentication controls, the environment is affected by CVE-2020-2838.
