Vulnerability in the Oracle Human Resources product of Oracle E-Business Suite (component: Hierarchy Diagrammers). Supported versions that are affected are 12.1.1-12.1.3 and 12.2.3-12.2.9. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Human Resources. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Human Resources accessible data as well as unauthorized access to critical data or complete access to all Oracle Human Resources accessible data. CVSS 3.0 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).

Security readout for executives and security teams

Plain-English summary

This is a high-severity Oracle E-Business Suite Human Resources flaw. A low-privileged user who can reach the HR application over HTTP could read or change critical HR data. The main business risk is unauthorized disclosure or tampering with employee and HR records, not service outage.

Executive priority

Prioritize remediation for any affected HR deployment because the issue can expose or alter sensitive employee data. Treat this as urgent for externally reachable or broadly internally accessible EBS HR systems.

Technical view

CVE-2020-2882 affects Oracle Human Resources in Oracle E-Business Suite, Hierarchy Diagrammers component, versions 12.1.1-12.1.3 and 12.2.3-12.2.9. Oracle rates it CVSS 8.1 with network attack vector, low complexity, low privileges, no user interaction, high confidentiality and integrity impact, and no availability impact.

Likely exposure

Exposure is likely where affected Oracle E-Business Suite HR versions are deployed and reachable over HTTP by authenticated low-privileged users. Internet exposure is not stated in the bundle; assess internal, VPN, partner, and externally published EBS access paths.

Exploitation context

The source bundle says the vulnerability is easily exploitable by a low-privileged attacker with network access via HTTP. It does not provide evidence of active exploitation, and KEV status is false. No exploit steps or public weaponization details are included in the provided sources.

Researcher notes

The bundle does not name a CWE or root cause. Use vendor advisory and ZDI material for patch identifiers and technical context. Validation should focus on affected version confirmation, patch status, reachable HTTP paths, and evidence of unauthorized HR data access or modification.

Mitigation direction

  • Review Oracle April 2020 Critical Patch Update guidance for this CVE.
  • Apply the applicable Oracle E-Business Suite Human Resources fixes.
  • Limit HTTP access to EBS HR to trusted networks and required users.
  • Enforce least privilege for HR application accounts.
  • Monitor HR data access and modification activity for anomalies.

Validation and detection

  • Inventory Oracle E-Business Suite HR versions in production and non-production.
  • Confirm whether versions fall within 12.1.1-12.1.3 or 12.2.3-12.2.9.
  • Verify the relevant Oracle CPU fixes are applied.
  • Map who can reach HR over HTTP, including VPN and partner paths.
  • Review logs for unusual HR data reads, creates, deletes, or modifications.
