Vulnerability in the Oracle Workflow product of Oracle E-Business Suite (component: Workflow Notification Mailer). Supported versions that are affected are 12.1.3 and 12.2.3-12.2.9. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Workflow. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Workflow accessible data. CVSS 3.0 Base Score 5.3 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

CVE-2020-2753 is an Oracle E-Business Suite Workflow issue that can let an unauthenticated network attacker alter some Workflow data over HTTP. The business risk is data integrity, not data theft or outage based on the supplied CVSS vector.

Executive priority

Treat this as a medium-priority integrity risk. It does not indicate confirmed exploitation or full system compromise from the supplied sources, but unauthenticated HTTP reachability justifies timely patch verification.

Technical view

The vulnerability affects Oracle Workflow, specifically Workflow Notification Mailer, in supported versions 12.1.3 and 12.2.3 through 12.2.9. CVSS 3.0 is 5.3 with network access, low complexity, no privileges, no user interaction, unchanged scope, and low integrity impact only.

Likely exposure

Exposure is most relevant where Oracle E-Business Suite Workflow is reachable over HTTP and running version 12.1.3 or 12.2.3-12.2.9. Internet-facing or broadly accessible internal deployments carry higher operational concern.

Exploitation context

The supplied sources do not show CISA KEV listing or active exploitation evidence. The vulnerability is still notable because Oracle describes it as easily exploitable without authentication over HTTP.

Researcher notes

No CWE is supplied in the bundle. The CVSS vector limits impact to integrity, so validation should focus on affected version confirmation, reachable Workflow surfaces, and patch state rather than assuming broader confidentiality or availability compromise.

Mitigation direction

  • Review Oracle April 2020 Critical Patch Update guidance for this CVE.
  • Apply the relevant Oracle E-Business Suite Workflow patches or later supported fixes.
  • Restrict HTTP access to Oracle E-Business Suite Workflow interfaces where possible.
  • Prioritize exposed or business-critical E-Business Suite environments first.

Validation and detection

  • Inventory Oracle E-Business Suite instances and enabled Workflow components.
  • Confirm whether Workflow Notification Mailer is present and exposed over HTTP.
  • Verify deployed versions against 12.1.3 and 12.2.3-12.2.9.
  • Check patch records for Oracle April 2020 CPU remediation coverage.
  • Review access logs for unexpected unauthenticated Workflow-related HTTP activity.
