Vulnerability in the Oracle Marketing Encyclopedia System product of Oracle E-Business Suite (component: Administration). Supported versions that are affected are 12.1.1-12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Marketing Encyclopedia System. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Marketing Encyclopedia System, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Marketing Encyclopedia System accessible data as well as unauthorized update, insert or delete access to some of Oracle Marketing Encyclopedia System accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

CVE-2020-2807 affects Oracle Marketing Encyclopedia System in Oracle E-Business Suite. An unauthenticated network attacker can abuse it over HTTP, but a separate user must interact. Impact is serious: critical data exposure and limited unauthorized data changes are possible.

Executive priority

Treat as a high-priority remediation for affected Oracle E-Business Suite environments because business data confidentiality is the main risk, with additional integrity impact. Prioritize internet-facing or widely accessible deployments first.

Technical view

Oracle lists affected Marketing Encyclopedia System versions 12.1.1 through 12.1.3, Administration component. CVSS 3.0 is 8.2: AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N. The vulnerability can expose all accessible MES data and modify some accessible data.

Likely exposure

Exposure is likely limited to organizations running Oracle E-Business Suite with Marketing Encyclopedia System 12.1.1-12.1.3. Risk increases where the HTTP interface is reachable by untrusted networks or broad internal user populations.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates unauthenticated network access over HTTP, low complexity, and required human interaction by someone other than the attacker.

Researcher notes

No CWE, proof-of-concept, or root-cause detail is provided in the source bundle. Avoid assuming exploit mechanics beyond the CVSS vector and Oracle description. Validation should focus on version exposure, patch state, and reachable HTTP surfaces.

Mitigation direction

  • Identify Oracle E-Business Suite instances using Marketing Encyclopedia System 12.1.1-12.1.3.
  • Review Oracle April 2020 CPU guidance and apply applicable vendor fixes.
  • Restrict HTTP access to trusted networks until remediation is complete.
  • Prioritize upgrade or vendor-supported mitigation for unsupported affected versions.
  • Monitor Oracle advisories for current E-Business Suite patch requirements.

Validation and detection

  • Confirm whether Marketing Encyclopedia System is deployed and enabled.
  • Inventory exact Oracle E-Business Suite and MES versions.
  • Verify applicable Oracle CPU patches are installed.
  • Review web access controls for MES HTTP endpoints.
  • Check logs for unusual access to MES administration functions.
