CVE-2020-2514: Vulnerability in the Oracle Application Express component of Oracle Database Server.

Vulnerability in the Oracle Application Express component of Oracle Database Server. The supported version that is affected is Prior to 19.2. Easily exploitable vulnerability allows low privileged attacker having End User Role privilege with network access via HTTPS to compromise Oracle Application Express. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Application Express accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Application Express. CVSS 3.0 Base Score 4.6 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L).

Security readout for executives and security teams

Plain-English summary

CVE-2020-2514 affects Oracle Application Express in Oracle Database Server before version 19.2. A low-privileged end user with HTTPS access could, with another user’s interaction, alter some APEX-accessible data or partially disrupt APEX. It is medium severity because impact is limited and requires privileges plus user interaction.

Executive priority

Treat as a scheduled remediation item unless APEX is broadly exposed or used for sensitive operational workflows. It is not a crisis-level CVE from the provided evidence, but affected systems can suffer data integrity changes and partial service disruption.

Technical view

The CVE is network-reachable over HTTPS, low attack complexity, requires low privileges and user interaction, and has unchanged scope. CVSS 3.0 is 4.6 with no confidentiality impact, low integrity impact, and low availability impact. Affected Oracle Application Express versions are described as prior to 19.2.

Likely exposure

Organizations running Oracle Application Express before 19.2 are the relevant exposure group. Risk is higher where APEX is reachable over networks used by untrusted or broadly provisioned end users. The sources do not identify specific configurations, modules, or deployments beyond Oracle Application Express.

Exploitation context

The provided bundle does not cite active exploitation, and the CVE is not marked KEV. Exploitation requires a low-privileged APEX end user, HTTPS network access, and human interaction by someone other than the attacker. The sources do not provide exploit maturity details.

Researcher notes

Focus validation on APEX versions prior to 19.2 and reachable HTTPS surfaces. The CVE record gives no CWE, no exploit details, and no product subcomponent beyond Oracle Application Express. Avoid assuming database-wide compromise; the stated impact is limited to some APEX-accessible data and partial APEX denial of service.

Mitigation direction

  • Identify Oracle Application Express deployments and versions.
  • Upgrade affected APEX installations from versions prior to 19.2.
  • Review Oracle April 2020 CPU guidance before remediation.
  • Restrict APEX access to trusted users and networks where practical.
  • Monitor APEX for unexpected data changes or availability issues.

Validation and detection

  • Inventory APEX version numbers across Oracle Database environments.
  • Confirm no production APEX instance remains below 19.2.
  • Verify HTTPS exposure and user-role access paths to APEX.
  • Review logs for unusual updates, inserts, deletes, or partial outages.
  • Document remediation status against Oracle CPU April 2020.
