CVE-2017-10043 in BI Publisher
Summary
by MITRE
Vulnerability in the BI Publisher component of Oracle Fusion Middleware (subcomponent: BI Publisher Security). Supported versions that are affected are 11.1.1.7.0 and 11.1.1.9.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise BI Publisher. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in BI Publisher, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all BI Publisher accessible data as well as unauthorized update, insert or delete access to some of BI Publisher 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).

The vulnerability identified as CVE-2017-10043 resides within the BI Publisher component of Oracle Fusion Middleware, specifically within the BI Publisher Security subcomponent. This flaw affects Oracle Fusion Middleware versions 11.1.1.7.0 and 11.1.1.9.0, representing a critical security weakness that exposes organizations to significant operational risks. The vulnerability's classification as easily exploitable indicates that attackers can leverage it with minimal technical sophistication, making it particularly dangerous in environments where proper network segmentation and access controls are not adequately implemented. The attack vector operates through HTTP network access, eliminating the need for authentication or privileged credentials, which significantly broadens the potential threat surface.
The technical implementation of this vulnerability stems from insufficient access controls and authentication mechanisms within the BI Publisher security framework. An unauthenticated attacker can exploit this weakness to gain unauthorized access to critical data stored within the BI Publisher environment, potentially compromising the confidentiality and integrity of sensitive business intelligence information. The vulnerability's impact extends beyond the immediate BI Publisher component, as successful exploitation can affect additional Oracle products within the same ecosystem, creating cascading security implications throughout the organization's technology infrastructure. The CVSS 3.0 score of 8.2 reflects the severity of potential consequences, with high confidentiality impact and low integrity impact, indicating that data exposure poses the primary risk while modification capabilities remain limited.
The operational impact of CVE-2017-10043 manifests through unauthorized access to sensitive business intelligence data, potentially exposing proprietary information, financial reports, strategic plans, or other confidential business data. The vulnerability enables attackers to achieve complete access to all BI Publisher accessible data, which could include customer information, financial records, operational metrics, and other critical business intelligence. Additionally, the flaw permits unauthorized update, insert, or delete operations on certain data within the BI Publisher accessible environment, creating potential for data corruption or manipulation that could significantly impact business operations and decision-making processes. Organizations relying on BI Publisher for critical reporting and analytics may face severe consequences including regulatory compliance violations, financial losses, and reputational damage if this vulnerability is exploited.
Mitigation strategies for CVE-2017-10043 should prioritize immediate patch management and system hardening measures. Organizations must implement the official Oracle security patches released for versions 11.1.1.7.0 and 11.1.1.9.0 to address the underlying authentication and access control weaknesses. Network-level protections should include implementing strict firewall rules to restrict HTTP access to BI Publisher services, particularly when the component is not essential for external access. Additional defensive measures encompass deploying intrusion detection systems to monitor for suspicious HTTP traffic patterns, implementing network segmentation to isolate BI Publisher components, and conducting regular security assessments to identify potential unauthorized access attempts. The vulnerability aligns with CWE-284, which addresses improper access control, and maps to ATT&CK techniques involving unauthorized access and data exposure, emphasizing the need for comprehensive security controls beyond simple patching to protect against sophisticated exploitation attempts.
