CVE-2020-14763: Vulnerability in the Oracle Application Express Quick Poll component of Oracle Database Server.

Vulnerability in the Oracle Application Express Quick Poll component of Oracle Database Server. The supported version that is affected is Prior to 20.2. Easily exploitable vulnerability allows low privileged attacker having Valid User Account privilege with network access via HTTP to compromise Oracle Application Express Quick Poll. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Application Express Quick Poll, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Application Express Quick Poll accessible data as well as unauthorized read access to a subset of Oracle Application Express Quick Poll accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

This issue affects Oracle Application Express Quick Poll before 20.2. A low-privileged authenticated user with HTTP access could, with another person’s interaction, read some Quick Poll data or make unauthorized changes. It is not described as a full system takeover, but it can affect data integrity and may impact connected products.

Executive priority

Treat this as a medium-priority remediation item for environments using APEX before 20.2. Prioritize internet-exposed or broadly accessible APEX systems because the issue can alter or disclose application data after user interaction.

Technical view

CVE-2020-14763 is a network-reachable Oracle APEX Quick Poll vulnerability with low attack complexity, low privileges required, and required user interaction. The CVSS 3.1 score is 5.4 with changed scope, low confidentiality impact, low integrity impact, and no availability impact.

Likely exposure

Organizations are mainly exposed if they run Oracle Application Express prior to 20.2, have Quick Poll present, and allow authenticated users HTTP access to the APEX environment.

Exploitation context

The source bundle does not cite active exploitation, and the CVE is not marked KEV. Exploitation requires a valid low-privileged account, network access over HTTP, and interaction by someone other than the attacker.

Researcher notes

Evidence is limited to the CVE description and Oracle advisory reference. The affected component is Quick Poll within Oracle Application Express, with impact limited to some accessible data. No exploit details or confirmed exploitation are provided in the bundle.

Mitigation direction

  • Review Oracle October 2020 CPU guidance for CVE-2020-14763.
  • Update Oracle APEX from versions prior to 20.2 using vendor guidance.
  • Restrict HTTP access to APEX to trusted users and networks.
  • Disable or remove unused Quick Poll functionality where operationally acceptable.
  • Review low-privileged account access to APEX applications.

Validation and detection

  • Inventory Oracle APEX instances and record installed versions.
  • Identify any APEX deployments prior to version 20.2.
  • Confirm whether Quick Poll is installed, enabled, or reachable.
  • Check whether low-privileged authenticated users can access relevant APEX paths.
  • Review logs for unusual Quick Poll data reads or modifications.
