CVE-2021-2140: Vulnerability in the Oracle Financial Services Analytical Applications Infrastructure product of Oracle Fin...

Vulnerability in the Oracle Financial Services Analytical Applications Infrastructure product of Oracle Financial Services Applications (component: Rules Framework). Supported versions that are affected are 8.0.6-8.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Financial Services Analytical Applications Infrastructure. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Financial Services Analytical Applications Infrastructure, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Financial Services Analytical Applications Infrastructure accessible data as well as unauthorized read access to a subset of Oracle Financial Services Analytical Applications Infrastructure accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

This vulnerability affects Oracle Financial Services Analytical Applications Infrastructure versions 8.0.6 through 8.1.0. An unauthenticated attacker with HTTP network access could trigger it if a separate user interacts with malicious content. Successful abuse could read or change some application-accessible data, but the source bundle does not show availability impact or confirmed exploitation.

Executive priority

Treat this as a moderate business risk for financial-services environments using affected Oracle software. Prioritize inventory and vendor-guided patching, especially where OFSAAI is externally reachable or used by personnel likely to receive untrusted links.

Technical view

CVE-2021-2140 is in the Rules Framework component of Oracle Financial Services Analytical Applications Infrastructure. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, score 6.1. It is remotely reachable over HTTP, requires user interaction, and can affect confidentiality and integrity across a changed scope.

Likely exposure

Exposure is limited to organizations running Oracle Financial Services Analytical Applications Infrastructure versions 8.0.6 through 8.1.0, especially where HTTP interfaces are reachable by untrusted users or networks.

Exploitation context

The provided sources do not indicate active exploitation, and the CVE is not marked KEV. Exploitation is described as easy, unauthenticated, and network-based over HTTP, but it requires human interaction from someone other than the attacker.

Researcher notes

The source bundle does not name a CWE, proof of concept, or fixed version. Analysis should stay tied to Oracle’s advisory and CVE metadata. Key triage factors are affected version range, HTTP reachability, user-interaction path, and potential partial data read or modification impact.

Mitigation direction

  • Identify all OFSAAI deployments and versions before prioritizing remediation.
  • Review Oracle April 2021 CPU guidance for the applicable patch or upgrade path.
  • Restrict OFSAAI HTTP access to trusted networks while remediation is pending.
  • Reduce phishing and unsafe-link exposure for users with access to OFSAAI.
  • Monitor vendor advisories for superseding fixes or support status changes.

Validation and detection

  • Confirm whether OFSAAI versions 8.0.6 through 8.1.0 are present.
  • Verify the Rules Framework component is included in deployed instances.
  • Check whether applicable Oracle CPU remediation has been applied.
  • Validate OFSAAI HTTP endpoints are not exposed beyond required networks.
  • Review access logs for unusual unauthenticated HTTP activity.
