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 iSupport product of Oracle E-Business Suite (component: User Responsibilities). Supported versions that are affected are 12.1.1-12.1.3 and 12.2.3-12.2.10. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle iSupport. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iSupport, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle iSupport accessible data as well as unauthorized update, insert or delete access to some of Oracle iSupport accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/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 · high confidence

An unauthenticated attacker can exploit Oracle iSupport's User Responsibilities component via HTTP to gain unauthorized access to sensitive data or perform unauthorized updates, inserts, or deletes. The attack requires human interaction (likely CSRF or social engineering), operates over the network with low complexity, and can impact additional products beyond iSupport due to scope changes.

MitigationApply Oracle's January 2021 Critical Patch Update (CPU) containing the fix for CVE-2021-2083. If immediate patching is not feasible, restrict network access to Oracle iSupport and implement additional authentication/multi-factor 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. Confirm Oracle iSupport is installed
    Check your system for Oracle iSupport application files or contact your Oracle administrator to verify iSupport is deployed in your environment
    Affected if Oracle iSupport is not installed on your system - this CVE does not apply
  2. Identify Oracle iSupport version
    Query the iSupport application or check Oracle Application Server version: look for version strings matching 12.1.x or 12.2.x in iSupport installation directories, Oracle Enterprise Manager, or application metadata
    Affected if The installed version falls outside 12.1.1 to 12.1.3 or 12.2.3 to 12.2.10 - only those ranges are affected
  3. Verify User Responsibilities component is accessible
    Check if the User Responsibilities module is enabled and accessible in the iSupport application by examining the application's component configuration or URL accessibility
    Affected if User Responsibilities component is not enabled or not accessible via HTTP - the vulnerability requires this component to be present and exposed
  4. Check HTTP interface exposure
    Determine if the iSupport HTTP listener is exposed to network access by reviewing web server configuration, load balancer rules, or firewall policies
    Affected if iSupport is only accessible via localhost or completely isolated internal network with no external attack surface - the vulnerability requires network accessibility

Your environment is affected if Oracle iSupport is installed with a version between 12.1.1-12.1.3 or 12.2.3-12.2.10, the User Responsibilities component is enabled, and the HTTP interface is network-accessible to potential attackers.
