CVE-2017-10029 in BI Publisher
Summary
by MITRE
Vulnerability in the BI Publisher component of Oracle Fusion Middleware (subcomponent: Web Server). The supported version that is affected is 11.1.1.7.0. 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-2017-10029 represents a critical security flaw within Oracle Fusion Middleware's BI Publisher component, specifically within its Web Server subcomponent. This vulnerability affects version 11.1.1.7.0 of the Oracle Fusion Middleware suite, which is a widely deployed enterprise application platform. The flaw exists in the way the system handles certain HTTP requests, creating an exploitable condition that can be leveraged by malicious actors without requiring authentication credentials. The vulnerability's classification as easily exploitable indicates that the attack vector is straightforward and accessible to threat actors with basic network connectivity, making it particularly dangerous in enterprise environments where such systems are commonly exposed to external networks.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the BI Publisher Web Server component. Attackers can exploit this weakness by crafting specific HTTP requests that bypass normal authentication procedures and gain unauthorized access to the underlying data repositories. The vulnerability's impact extends beyond the immediate BI Publisher component, as successful exploitation can lead to cascading effects that compromise additional Oracle products within the same ecosystem. This interconnected nature of the vulnerability aligns with ATT&CK technique T1078 which describes valid accounts usage and T1190 which covers exploitation of remote services. The flaw essentially allows an unauthenticated attacker to perform unauthorized operations that can result in complete data compromise and modification capabilities.
The operational impact of CVE-2017-10029 is severe and multifaceted, as demonstrated by the CVSS 3.0 base score of 8.2 which indicates high severity. The vulnerability can lead to unauthorized access to critical business intelligence data, potentially exposing sensitive corporate information, financial records, and strategic planning documents. The confidentiality impact is rated as high (C:H) because attackers can access all data accessible through BI Publisher without authentication, while the integrity impact is rated as low (I:L) as the vulnerability allows for unauthorized update, insert, or delete operations on some data. The fact that human interaction is required for successful exploitation suggests that the attack may involve social engineering elements or require specific conditions to be met, though this does not mitigate the overall risk. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) clearly shows that the attack requires no privileges, has low complexity, and can be executed remotely, making it particularly attractive to automated attack tools.
Organizations affected by this vulnerability should implement immediate mitigations including network segmentation to limit access to the affected BI Publisher instances, deployment of web application firewalls to monitor and filter HTTP requests, and implementation of strict access controls for the Web Server component. The vulnerability's classification under CWE-287 (Improper Authentication) and its alignment with ATT&CK techniques highlight the need for comprehensive security measures beyond simple patching. Security teams should also conduct thorough audits of their Oracle Fusion Middleware deployments to identify all instances of the vulnerable version and ensure proper patch management procedures are in place. Additionally, monitoring for unusual HTTP request patterns and implementing intrusion detection systems can help identify potential exploitation attempts. The vulnerability's potential for significant data compromise makes it essential for organizations to review their incident response procedures and ensure they can quickly detect and respond to unauthorized access attempts. Organizations should also consider implementing additional layers of security such as multi-factor authentication and regular security assessments to reduce the attack surface and protect against similar vulnerabilities in other components of their Oracle infrastructure.
