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 Common Applications product of Oracle E-Business Suite (component: CRM User Management Framework). 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 Common Applications. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Common Applications, 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 Common Applications accessible data as well as unauthorized update, insert or delete access to some of Oracle Common Applications 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

SQL injection or authentication bypass in Oracle E-Business Suite's CRM User Management Framework allows unauthenticated remote attackers to access, modify, or delete sensitive data. The vulnerability requires human interaction (likely phishing) and can impact additional products beyond the directly affected Oracle Common Applications component.

MitigationApply Oracle Critical Patch Update (CPU) patches for CVE-2021-2093 to affected E-Business Suite versions 12.1.1-12.1.3 and 12.2.3-12.2.10. Restrict HTTP exposure to CRM User Management Framework interfaces and monitor for suspicious activity.

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 Oracle E-Business Suite installation
    Locate Oracle E-Business Suite components in your environment by querying application servers, checking for Oracle Middleware home directories, or reviewing installed enterprise applications
    Affected if Oracle E-Business Suite is present in the environment
  2. Determine Oracle Common Applications version
    Query the Oracle Applications version through the application's About page, adident utility, or version information tables in the Oracle database
    Affected if Version is 12.1.1 through 12.1.3 OR 12.2.3 through 12.2.10
  3. Check CRM User Management Framework exposure
    Identify if the CRM User Management Framework web interfaces (typically under /OA_HTML/umf or similar paths) are accessible from the network by reviewing web server configuration and URL access logs
    Affected if The User Management Framework interface is exposed to network access
  4. Verify authentication configuration
    Review the authentication settings for the User Management Framework component in Oracle Applications Manager (OAM) or the related configuration files to confirm whether authentication is properly enforced
    Affected if Authentication is not properly enforced or can be bypassed for the CRM User Management Framework

You are affected if Oracle E-Business Suite with Oracle Common Applications versions 12.1.1-12.1.3 or 12.2.3-12.2.10 is running and the CRM User Management Framework is network-accessible without proper authentication controls.
