CVE-2021-2188: Vulnerability in the Oracle iStore product of Oracle E-Business Suite (component: Shopping Cart).

Vulnerability in the Oracle iStore product of Oracle E-Business Suite (component: Shopping Cart). 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 iStore. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iStore, 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 iStore accessible data as well as unauthorized update, insert or delete access to some of Oracle iStore 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-2021-2188 affects Oracle iStore Shopping Cart in Oracle E-Business Suite. An unauthenticated attacker reachable over HTTP could compromise iStore data if a separate user interacts with the attack. The main business risk is exposure of critical iStore data and unauthorized changes to some accessible data.

Executive priority

Treat as high priority where Oracle iStore is externally reachable or handles sensitive customer, order, or account data. The issue can expose critical data and permit some unauthorized data modification, though the provided sources do not confirm active exploitation.

Technical view

Oracle reports affected iStore versions 12.1.1-12.1.3 and 12.2.3-12.2.10. CVSS 3.1 is 8.2 with network attack vector, low complexity, no privileges required, required user interaction, changed scope, high confidentiality impact, and low integrity impact. CWE is not specified in the provided sources.

Likely exposure

Organizations using Oracle E-Business Suite with Oracle iStore Shopping Cart on the listed versions are potentially exposed, especially where iStore is reachable over HTTP from untrusted networks.

Exploitation context

The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. Oracle describes the issue as easily exploitable over HTTP by an unauthenticated attacker, but successful exploitation requires human interaction by someone other than the attacker.

Researcher notes

Do not assume a specific flaw class; CWE is absent. Focus validation on version presence, iStore Shopping Cart exposure, HTTP reachability, user-interaction paths, and patch status from Oracle’s April 2021 CPU. Avoid claiming exploit availability without additional evidence.

Mitigation direction

  • Inventory Oracle E-Business Suite deployments running iStore Shopping Cart on affected versions.
  • Review Oracle April 2021 Critical Patch Update guidance for the relevant iStore fixes.
  • Prioritize remediation for internet-facing or partner-facing iStore instances.
  • Restrict HTTP access to iStore where business operations allow until vendor guidance is applied.
  • Monitor iStore activity for unusual data access or unauthorized data modifications.

Validation and detection

  • Confirm whether Oracle iStore Shopping Cart is enabled in E-Business Suite.
  • Check deployed E-Business Suite/iStore versions against 12.1.1-12.1.3 and 12.2.3-12.2.10.
  • Verify applicable Oracle CPU patches or vendor-recommended updates are installed.
  • Review exposure paths for HTTP access from external or lower-trust networks.
  • Check logs for suspicious iStore access patterns around user-driven workflows.
