Vulnerability in the Oracle BI Publisher product of Oracle Fusion Middleware (component: BI Publisher Security). Supported versions that are affected are 5.5.0.0.0, 11.1.1.9.0, 12.2.1.3.0 and 12.2.1.4.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle BI Publisher. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle BI Publisher accessible data as well as unauthorized update, insert or delete access to some of Oracle BI Publisher accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle BI Publisher. CVSS 3.1 Base Score 7.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L).

Security readout for executives and security teams

Plain-English summary

CVE-2021-2013 is a high-severity Oracle BI Publisher vulnerability. A low-privileged user with HTTP network access could compromise BI Publisher data, including full unauthorized read access, limited data modification, and partial service disruption. This matters most where BI Publisher is reachable by broad user populations or exposed beyond trusted networks.

Executive priority

Treat as a near-term remediation item for BI Publisher environments, especially if the platform contains sensitive reporting data or is reachable by many authenticated users. Prioritize patch verification and access restriction before routine backlog work.

Technical view

The issue affects Oracle BI Publisher Security in versions 5.5.0.0.0, 11.1.1.9.0, 12.2.1.3.0, and 12.2.1.4.0. CVSS 3.1 is 7.6 with network attack vector, low complexity, low privileges required, no user interaction, high confidentiality impact, and low integrity and availability impact.

Likely exposure

Organizations running affected Oracle BI Publisher versions are exposed if attackers can reach the BI Publisher HTTP interface and authenticate with low privileges. Internet-facing, partner-accessible, or broadly internal deployments carry higher business risk.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates exploitation is considered easy once a low-privileged attacker has HTTP access, but no exploit details are provided.

Researcher notes

No CWE is provided in the source bundle. The strongest evidence is the CVE description, CVSS vector, affected version list, and Oracle CPU reference. Avoid assuming root cause, exploit availability, or fixes beyond Oracle guidance.

Mitigation direction

  • Identify all Oracle BI Publisher deployments and versions.
  • Review Oracle January 2021 CPU guidance for CVE-2021-2013.
  • Apply the relevant Oracle-supported BI Publisher update or fix.
  • Restrict HTTP access to trusted networks and users where feasible.
  • Review BI Publisher privileges for unnecessary low-privileged access.

Validation and detection

  • Confirm whether any instance runs an affected listed version.
  • Verify the Oracle CPU fix level for BI Publisher.
  • Map who can reach BI Publisher over HTTP.
  • Review logs for unusual low-privileged data access or changes.
  • Document compensating controls if patching is delayed.
