CVE-2020-2843: Vulnerability in the Oracle iSupport product of Oracle E-Business Suite (component: Profile).

Vulnerability in the Oracle iSupport product of Oracle E-Business Suite (component: Profile). 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 iSupport. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iSupport, 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 iSupport accessible data as well as unauthorized update, insert or delete access to some of Oracle iSupport 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-2020-2843 affects Oracle iSupport in Oracle E-Business Suite versions 12.1.1 through 12.1.3. An unauthenticated attacker who can reach the service over HTTP could compromise sensitive iSupport data if a separate user interacts with the attack. The issue is high severity because it can expose critical data and allow limited data modification.

Executive priority

Treat this as a high-priority legacy Oracle E-Business Suite exposure review. Internet-facing or partner-facing iSupport instances should be handled first because the impact includes critical data disclosure and some unauthorized data changes.

Technical view

Oracle describes this as an easily exploitable Profile component vulnerability in Oracle iSupport. The CVSS 3.0 score is 8.2: network attack vector, low complexity, no privileges required, user interaction required, changed scope, high confidentiality impact, low integrity impact, and no availability impact.

Likely exposure

Exposure is most likely where Oracle E-Business Suite includes Oracle iSupport versions 12.1.1 through 12.1.3 and the iSupport HTTP interface is reachable by untrusted users or the internet.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability is still concerning because Oracle says it is remotely reachable over HTTP without authentication, although successful exploitation requires user interaction.

Researcher notes

Evidence is limited to the CVE description and Oracle CPU reference. No CWE, proof-of-concept status, or detailed root cause is provided. Scope is changed, meaning compromise of Oracle iSupport may significantly affect additional products.

Mitigation direction

  • Inventory Oracle E-Business Suite deployments for iSupport 12.1.1 through 12.1.3.
  • Review Oracle April 2020 CPU guidance and apply applicable vendor fixes.
  • Restrict HTTP exposure to trusted networks until remediation is verified.
  • Prioritize systems handling customer support, profile, or sensitive account data.
  • Monitor vendor advisories if patch applicability is unclear for your deployment.

Validation and detection

  • Confirm installed Oracle iSupport version and Profile component exposure.
  • Verify whether April 2020 CPU fixes are applied.
  • Check whether iSupport HTTP endpoints are internet-accessible or broadly reachable.
  • Review access logs for suspicious unauthenticated requests to iSupport paths.
  • Confirm compensating controls do not break required support workflows.
