CVE-2021-2198: Vulnerability in the Oracle Knowledge Management product of Oracle E-Business Suite (component: Setup, Admin).

Vulnerability in the Oracle Knowledge Management product of Oracle E-Business Suite (component: Setup, Admin). Supported versions that are affected are 12.1.1-12.1.3 and 12.2.3-12.2.10. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Knowledge Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Knowledge Management, 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 Knowledge Management accessible data as well as unauthorized update, insert or delete access to some of Oracle Knowledge Management accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/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-2021-2198 is a high-severity Oracle E-Business Suite Knowledge Management flaw. An unauthenticated attacker reachable over HTTP could compromise sensitive Knowledge Management data if a separate user interacts with the attack. The main business risk is critical data disclosure, with some risk of unauthorized data changes.

Executive priority

Treat as a high-priority remediation item for affected EBS environments, especially internet-accessible or partner-accessible deployments. The issue can expose critical data and allow limited data modification, but available sources do not establish active exploitation.

Technical view

The issue affects Oracle Knowledge Management Setup/Admin in supported EBS versions 12.1.1-12.1.3 and 12.2.3-12.2.10. CVSS 3.1 is 8.2: network reachable, low complexity, no privileges, user interaction required, changed scope, high confidentiality impact, low integrity impact, no availability impact.

Likely exposure

Exposure is likely limited to organizations running affected Oracle E-Business Suite Knowledge Management versions with HTTP access reachable by untrusted users. Human interaction is required, but no attacker authentication is needed.

Exploitation context

The source bundle does not show CISA KEV listing or other evidence of active exploitation. It does state easy exploitation over HTTP, no privileges required, and required interaction from a non-attacker user.

Researcher notes

No CWE is provided in the source bundle. The vulnerability is in Oracle Knowledge Management but may impact additional products through changed scope. Avoid assuming a specific exploit technique beyond unauthenticated HTTP access plus user interaction.

Mitigation direction

  • Review Oracle's April 2021 Critical Patch Update guidance for CVE-2021-2198.
  • Apply applicable Oracle E-Business Suite Knowledge Management security patches per vendor instructions.
  • Restrict HTTP access to EBS administrative and Knowledge Management surfaces where feasible.
  • Prioritize systems containing sensitive customer, support, or operational knowledge-base data.
  • Monitor Oracle advisories for superseding patch or mitigation guidance.

Validation and detection

  • Inventory Oracle E-Business Suite instances and Knowledge Management component usage.
  • Check whether versions are 12.1.1-12.1.3 or 12.2.3-12.2.10.
  • Confirm applicable Oracle CPU patches are installed on affected systems.
  • Review whether affected HTTP endpoints are exposed to untrusted networks.
  • Look for unusual unauthenticated HTTP activity and suspicious Knowledge Management data changes.
