CVE-2021-35665: Vulnerability in the Hyperion Financial Reporting product of Oracle Hyperion (component: Repository).

Vulnerability in the Hyperion Financial Reporting product of Oracle Hyperion (component: Repository). The supported version that is affected is 11.2.6.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Hyperion Financial Reporting. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Hyperion Financial Reporting, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Hyperion Financial Reporting accessible data as well as unauthorized read access to a subset of Hyperion Financial Reporting 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

CVE-2021-35665 affects Oracle Hyperion Financial Reporting 11.2.6.0. An unauthenticated network attacker could use HTTP and user interaction to read some accessible reporting data or modify some data. The business risk is data integrity and confidentiality in financial reporting, not system outage.

Executive priority

Treat as a moderate-priority financial reporting data risk. It is not listed as actively exploited in the supplied evidence, but affected systems should be checked promptly because unauthorized data changes or reads could affect reporting confidence.

Technical view

Oracle describes an easily exploitable Repository component issue in Hyperion Financial Reporting. The vector is network-accessible over HTTP, low complexity, no privileges required, user interaction required, and changed scope. Impacts are low confidentiality and low integrity, with no availability impact. CVSS 3.1 score is 6.1.

Likely exposure

Exposure is most likely where Oracle Hyperion Financial Reporting 11.2.6.0 is deployed and reachable over HTTP by users or adjacent networks. The supplied sources name only this supported version and product, so broader Hyperion exposure should not be assumed without inventory evidence.

Exploitation context

The source bundle does not show CISA KEV listing or other evidence of active exploitation. Exploitation requires interaction from someone other than the attacker, which lowers immediacy but still matters for finance systems because reporting data can influence decisions and controls.

Researcher notes

Key constraints are the narrow affected version and user-interaction requirement. The sources do not provide CWE, exploit proof, or detailed patch mechanics. Validate exposure through asset inventory and network reachability, then align remediation with Oracle’s CPU guidance.

Mitigation direction

  • Review Oracle October 2021 CPU guidance for vendor-confirmed remediation.
  • Prioritize remediation for internet-facing or broadly reachable Hyperion deployments.
  • Restrict HTTP access to trusted networks where operationally possible.
  • Use user awareness controls for suspicious links targeting Hyperion users.
  • Monitor vendor advisories for any updated fix or workaround details.

Validation and detection

  • Inventory Oracle Hyperion Financial Reporting deployments and versions.
  • Confirm whether version 11.2.6.0 exists in production or test.
  • Map HTTP exposure paths to the Repository component.
  • Review access logs for unusual Hyperion Financial Reporting activity.
  • Check patch status against Oracle October 2021 CPU guidance.
