CVE-2020-14762: 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 20.2. Easily exploitable vulnerability allows low privileged attacker having SQL Workshop privilege with network access via HTTP to compromise Oracle Application Express. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Application Express, 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 accessible data as well as unauthorized read access to a subset of Oracle Application Express 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

CVE-2020-14762 affects Oracle Application Express before 20.2. A low-privileged user with SQL Workshop access can, with another user's interaction, read some APEX-accessible data and change some data. It is not listed as known exploited in the source bundle.

Executive priority

Treat this as a targeted medium-priority remediation item. It is not described as actively exploited, but it can alter or expose business data where vulnerable APEX deployments and SQL Workshop access exist.

Technical view

The issue is in Oracle Application Express within Oracle Database Server. It is network reachable over HTTP, low complexity, requires low privileges and user interaction, and has changed scope. Impact is limited confidentiality and integrity loss, with no availability impact. CVSS 3.1 score is 5.4.

Likely exposure

Exposure is most likely where Oracle APEX prior to 20.2 is deployed, reachable over HTTP, and users have SQL Workshop privileges. The sources do not identify specific deployments, configurations, or downstream products beyond noting possible impact to additional products.

Exploitation context

The CVE describes the flaw as easily exploitable but requiring human interaction from someone other than the attacker. The source bundle does not include CISA KEV status or other cited evidence of active exploitation.

Researcher notes

No CWE is provided in the source bundle. The affected range is stated as prior to 20.2, but detailed vulnerable subversions and configuration-specific behavior are not included. Validate privilege paths, user-interaction assumptions, and APEX-accessible data scope before assigning business impact.

Mitigation direction

  • Identify Oracle APEX deployments running versions prior to 20.2.
  • Review Oracle's October 2020 Critical Patch Update guidance.
  • Upgrade APEX to a non-affected supported version where applicable.
  • Restrict SQL Workshop privileges to users with a clear business need.
  • Limit HTTP exposure to trusted networks where operationally feasible.

Validation and detection

  • Inventory Oracle APEX versions across production and non-production environments.
  • Confirm whether SQL Workshop privileges are assigned to low-privileged users.
  • Check whether APEX is reachable over HTTP from untrusted networks.
  • Review change logs for unauthorized APEX data reads or modifications.
  • Document any dependent products that consume APEX-accessible data.
