CVE-2021-2460: Vulnerability in the Oracle Application Express Data Reporter component of Oracle Database Server.

Vulnerability in the Oracle Application Express Data Reporter component of Oracle Database Server. The supported version that is affected is Prior to 21.1.0.00.04. Easily exploitable vulnerability allows low privileged attacker having Valid User Account privilege with network access via HTTP to compromise Oracle Application Express Data Reporter. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Application Express Data Reporter, 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 Data Reporter accessible data as well as unauthorized read access to a subset of Oracle Application Express Data Reporter 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 Oracle APEX Data Reporter flaw can let an authenticated low-privilege user, with another person’s interaction, read or change some Data Reporter-accessible data. It is not described as unauthenticated or availability-impacting, but it can affect confidentiality and integrity in business data workflows.

Executive priority

Prioritize in the normal Oracle patch cycle, or faster if APEX is broadly accessible or handles sensitive reporting data. The main business risk is unauthorized data reading or modification by an authenticated user.

Technical view

CVE-2021-2460 affects Oracle Application Express Data Reporter before 21.1.0.00.04. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, meaning network access over HTTP, low privileges, required user interaction, changed scope, and low confidentiality/integrity impact.

Likely exposure

Exposure is likely where Oracle APEX versions prior to 21.1.0.00.04 are deployed and reachable over HTTP by authenticated users. Risk increases if APEX is available to broad user groups or supports sensitive reporting workflows.

Exploitation context

The source bundle states the issue is easily exploitable by a low-privileged attacker with a valid account and HTTP access, but requires interaction by another person. KEV is false, and no provided source states active exploitation.

Researcher notes

Evidence is limited to CVE and Oracle advisory metadata. The bundle does not include root cause details, exploit examples, or product-specific configuration conditions beyond APEX Data Reporter before 21.1.0.00.04.

Mitigation direction

  • Apply Oracle July 2021 Critical Patch Update guidance for affected Oracle APEX deployments.
  • Upgrade Oracle APEX to 21.1.0.00.04 or later where applicable.
  • Restrict APEX HTTP access to trusted networks and required user groups.
  • Review low-privilege APEX accounts and remove unnecessary access.
  • Monitor Oracle guidance for environment-specific patching instructions.

Validation and detection

  • Inventory Oracle APEX deployments and record exact version numbers.
  • Confirm no exposed APEX instance is earlier than 21.1.0.00.04.
  • Verify Oracle July 2021 CPU remediation status for affected systems.
  • Map which authenticated user groups can reach APEX over HTTP.
  • Review audit logs for unexpected Data Reporter read or write activity.
