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 Advanced Outbound Telephony product of Oracle E-Business Suite (component: User Interface). Supported versions that are affected are 12.1.1-12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Advanced Outbound Telephony. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Advanced Outbound Telephony, 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 Advanced Outbound Telephony accessible data as well as unauthorized update, insert or delete access to some of Oracle Advanced Outbound Telephony accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/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

Oracle Advanced Outbound Telephony UI component in E-Business Suite versions 12.1.1-12.1.3 contains a vulnerability exploitable via HTTP by unauthenticated remote attackers. Successful exploitation allows unauthorized access to critical data and unauthorized modification (insert/update/delete) of some accessible data, requiring human interaction (e.g., tricking a user into clicking a malicious link).

MitigationApply Oracle Critical Patch Update (CPU) patches for CVE-2020-2856 to Oracle E-Business Suite 12.1.x. Until patches are applied, restrict network access to the Oracle Advanced Outbound Telephony interface through network segmentation or web application firewall rules.

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
    Query the database or check the APPL_TOP for Oracle E-Business Suite installation: SELECT product_version FROM apps.fnd_product_groups WHERE product_group_name LIKE 'E-Business Suite%'; or check $APPL_TOP/$APPLLOG for version files.
    Affected if E-Business Suite version is 12.1.x (12.1.1 through 12.1.3)
  2. Locate Oracle Advanced Outbound Telephony component
    Check if the Advanced Outbound Telephony module is installed by querying: SELECT patch_level FROM apps.fnd_patch_service_levels WHERE patch_level LIKE '%Advanced%Outbound%'; or check the Oracle Applications Manager (OAM) for installed modules.
    Affected if The Advanced Outbound Telephony component is present in the E-Business Suite installation
  3. Determine Advanced Outbound Telephony version
    Query the specific version of the Advanced Outbound Telephony module: SELECT a.application_name, b.release_name FROM apps.fnd_application a, apps.fnd_application_tl b WHERE a.application_id = b.application_id AND a.application_name LIKE '%Advanced%Outbound%'; or check the Oracle HTML DB interface for module version information.
    Affected if Version falls within range >= 12.1.1 and <= 12.1.3
  4. Verify HTTP accessibility of the UI component
    Check if the Oracle Advanced Outbound Telephony web interface is accessible over HTTP/HTTPS by attempting to access the endpoint or reviewing web server configuration files in $IAS_ORACLE_HOME/Apache/Apache/conf for URL mappings to the Advanced Outbound Telephony module.
    Affected if The UI component is exposed via HTTP and accessible to network users

User is affected if Oracle E-Business Suite 12.1.x with Oracle Advanced Outbound Telephony component version 12.1.1-12.1.3 is installed and the UI is network-accessible via HTTP.
