CVE-2017-10119 in Service Bus
Summary
by MITRE
Vulnerability in the Oracle Service Bus component of Oracle Fusion Middleware (subcomponent: OSB Web Console Design, Admin). The supported version that is affected is 11.1.1.9.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Service Bus. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Service Bus, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Service Bus accessible data as well as unauthorized update, insert or delete access to some of Oracle Service Bus accessible data. CVSS 3.0 Base Score 7.6 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2017-10119 resides within Oracle Service Bus component of Oracle Fusion Middleware, specifically targeting the OSB Web Console Design and Admin subcomponents. This flaw affects version 11.1.1.9.0 of the software stack, representing a significant security weakness in enterprise service bus implementations. The vulnerability operates at the application layer and requires network access via HTTP protocols, making it accessible to remote attackers who can leverage standard web-based exploitation techniques. The security implications extend beyond the immediate component, as successful exploitation can potentially impact additional Oracle products within the same ecosystem, creating cascading security risks for organizations relying on Oracle Fusion Middleware solutions.
The technical nature of this vulnerability stems from insufficient access controls and authentication mechanisms within the Oracle Service Bus web console interfaces. Attackers with low privilege levels can exploit this weakness to gain unauthorized access to sensitive data and potentially modify system configurations. The vulnerability's classification as easily exploitable indicates that the attack vector requires minimal technical sophistication, though it does necessitate human interaction from users other than the attacker, suggesting a social engineering component or user-based exploitation scenario. The CVSS 3.0 score of 7.6 reflects the severity with which this vulnerability can be leveraged, particularly given the high confidentiality impact and moderate integrity impact it can cause. The vector notation AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N indicates network-based access with low attack complexity, requiring only low privileges, but needing user interaction, with a potentially catastrophic impact on confidentiality while affecting integrity moderately.
The operational impact of CVE-2017-10119 extends far beyond simple data theft, as successful exploitation can lead to complete access to all Oracle Service Bus accessible data, including sensitive enterprise service configurations, integration workflows, and business-critical service endpoints. Attackers can potentially modify service definitions, alter data flow routing, and compromise the integrity of service bus operations. The vulnerability also allows unauthorized update, insert, and delete operations on accessible data, providing attackers with comprehensive control over the service bus environment. This type of vulnerability directly maps to CWE-284 (Improper Access Control) and aligns with ATT&CK techniques related to privilege escalation and credential access. Organizations using this vulnerable version face significant risk of service disruption, data compromise, and potential regulatory violations, particularly in environments where service bus components manage critical business processes and sensitive data flows.
Mitigation strategies for this vulnerability should prioritize immediate patching of Oracle Service Bus to versions that address the access control weaknesses. Organizations should implement network segmentation to limit access to the service bus web console interfaces, particularly restricting access to trusted administrative networks. Additional defensive measures include implementing robust authentication mechanisms, enabling multi-factor authentication for administrative access, and conducting regular security audits of service bus configurations. Network monitoring should be enhanced to detect unusual access patterns or unauthorized attempts to interact with the web console. Security teams should also consider implementing web application firewalls to filter malicious HTTP requests targeting the vulnerable interfaces. The vulnerability highlights the importance of maintaining up-to-date security patches and conducting regular vulnerability assessments of enterprise middleware components to prevent exploitation of known weaknesses that could lead to significant operational and security impacts.
