CVE-2017-10028 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-2017-10028 resides within the BI Publisher component of Oracle Fusion Middleware, specifically within the Web Server subcomponent. This flaw affects version 11.1.1.7.0 of the software, representing a critical security weakness that can be exploited by unauthenticated attackers. The vulnerability operates through HTTP network access, making it particularly dangerous as it requires no prior authentication credentials to initiate exploitation attempts. The affected system represents a core component of Oracle's enterprise reporting and publishing infrastructure, which typically handles sensitive business intelligence data and document generation processes.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the BI Publisher Web Server implementation. Attackers can leverage this weakness to gain unauthorized access to critical data within the BI Publisher environment, potentially achieving complete access to all accessible data through HTTP connections. The vulnerability's characteristics indicate a path traversal or directory traversal flaw that allows attackers to bypass normal authentication procedures and directly access internal system resources. This type of vulnerability typically manifests through improper handling of user-supplied input parameters that are processed by the web server component without adequate sanitization or validation checks.
From an operational impact perspective, successful exploitation of this vulnerability can result in severe consequences for organizations relying on Oracle Fusion Middleware. The CVSS 3.0 base score of 8.2 reflects the high severity nature of this flaw, with confidentiality and integrity impacts rated as high. Attackers can potentially access sensitive business intelligence data, financial reports, and other critical information that BI Publisher typically manages. Additionally, the vulnerability enables unauthorized modification capabilities, allowing attackers to insert, update, or delete data within the system. The requirement for human interaction suggests that while the initial exploitation might be automated, successful compromise often requires some form of user engagement or specific conditions that may involve social engineering or targeted attacks against specific personnel.
The security implications extend beyond the immediate BI Publisher component, as the attack vector can significantly impact additional Oracle products within the Fusion Middleware ecosystem. This interconnected nature of the vulnerability means that compromise of one component can potentially lead to broader system infiltration. Organizations utilizing this version of Oracle Fusion Middleware face substantial risk exposure, particularly in environments where the BI Publisher component handles sensitive corporate data or serves as a gateway to other critical systems. The vulnerability's classification as easily exploitable indicates that attackers with basic technical skills can leverage this weakness without requiring extensive resources or specialized knowledge. This characteristic makes it particularly dangerous in environments where security monitoring may be insufficient or where the affected systems are exposed to untrusted network traffic.
Mitigation strategies for CVE-2017-10028 should prioritize immediate patching of the affected Oracle Fusion Middleware version, as this represents the most effective defense against exploitation attempts. Organizations should implement network segmentation to limit access to the affected BI Publisher component, particularly restricting direct HTTP access from untrusted networks. Additional protective measures include implementing robust web application firewalls to monitor and filter HTTP requests, deploying intrusion detection systems to identify potential exploitation attempts, and conducting comprehensive network access reviews to ensure that only authorized personnel can access the vulnerable component. Security monitoring should focus on identifying unusual access patterns or attempts to access restricted BI Publisher resources. The vulnerability aligns with CWE-20 (Improper Input Validation) and may map to ATT&CK techniques involving initial access through web application exploitation and privilege escalation through data manipulation. Organizations should also consider implementing comprehensive backup and recovery procedures to ensure rapid restoration of compromised systems and establish incident response protocols specifically addressing this type of vulnerability.
