CVE-2017-10170 in Field Service
Summary
by MITRE
Vulnerability in the Oracle Field Service component of Oracle E-Business Suite (subcomponent: Wireless/WAP). Supported versions that are affected are 12.1.1, 12.1.2 and 12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Field Service. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Field Service, 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 Field Service accessible data as well as unauthorized update, insert or delete access to some of Oracle Field Service 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-2017-10170 resides within the Oracle Field Service component of Oracle E-Business Suite, specifically within the Wireless/WAP subcomponent. This flaw affects Oracle E-Business Suite versions 12.1.1, 12.1.2, and 12.1.3, representing a significant security weakness that has persisted across multiple release versions. The vulnerability operates at the application layer and is classified as easily exploitable, indicating that attackers can leverage it with minimal technical sophistication. The security implications extend beyond the immediate component, as successful exploitation can compromise not only Oracle Field Service but also impact additional Oracle products within the ecosystem. The vulnerability's accessibility via HTTP protocol means that attackers can potentially exploit it from remote locations without requiring physical access to the network infrastructure. This characteristic aligns with the CVSS 3.0 base score of 8.2, which reflects a high severity level based on the combination of confidentiality and integrity impacts. The attack vector AV:N indicates network-based exploitation, while AC:L suggests low attack complexity, making this vulnerability particularly dangerous for organizations that have not implemented proper network segmentation or access controls.
The technical nature of this vulnerability stems from insufficient authentication and authorization mechanisms within the Wireless/WAP functionality of Oracle Field Service. Attackers can potentially gain unauthorized access to critical data and achieve complete access to all data accessible through Oracle Field Service. The vulnerability enables unauthorized update, insert, or delete operations on some Oracle Field Service accessible data, creating a comprehensive compromise scenario where both data confidentiality and integrity are at risk. The requirement for human interaction from a person other than the attacker indicates that while the initial exploitation may be automated, successful compromise often requires some form of social engineering or user involvement. This aspect of the vulnerability makes it particularly insidious as it can be difficult to detect through automated security monitoring systems. The CVSS vector specifically highlights the critical nature of this flaw with a high confidentiality impact score of C:H and a moderate integrity impact score of I:L, suggesting that while the attacker can access sensitive information, they can also potentially modify data with limited impact on system availability. The score S:C indicates that the vulnerability can affect a large number of products within the Oracle ecosystem, not just the primary target.
The operational impact of CVE-2017-10170 extends far beyond immediate data compromise, as it can lead to significant business disruption and financial loss. Organizations utilizing Oracle Field Service may face unauthorized access to sensitive customer information, service records, and operational data that could be exploited for competitive advantage or malicious purposes. The ability to perform unauthorized data modifications creates risks for operational continuity, as field service technicians and managers may receive incorrect information that could lead to service failures or safety issues. The vulnerability's potential to affect multiple Oracle products within the E-Business Suite ecosystem means that organizations may experience cascading effects, where compromise of one component can lead to broader system infiltration. This vulnerability particularly impacts organizations that rely heavily on mobile field service operations, where wireless connectivity and WAP functionality are essential for real-time service delivery. The risk of data corruption or manipulation is especially concerning for field service operations that depend on accurate information for scheduling, inventory management, and customer service activities. Organizations may also face regulatory compliance issues if sensitive data is accessed or modified without authorization, particularly in industries governed by data protection regulations such as healthcare, finance, or government sectors.
Mitigation strategies for CVE-2017-10170 should include immediate patch application from Oracle, as this represents the most effective defense against the vulnerability. Organizations should implement network segmentation to limit access to Oracle Field Service components, particularly those with wireless/WAP functionality, and deploy firewalls with strict access controls to prevent unauthorized HTTP access. The implementation of multi-factor authentication and strong access controls should be enforced for all users accessing Oracle Field Service, especially those with administrative privileges. Network monitoring and intrusion detection systems should be configured to detect unusual access patterns or attempts to access the vulnerable Wireless/WAP functionality. Regular security assessments and vulnerability scanning should be conducted to identify potential exploitation attempts and ensure that security measures remain effective. Organizations should also consider implementing application-level controls and access logging to track user activities and detect potential unauthorized access. The principle of least privilege should be applied to all Oracle Field Service accounts, ensuring that users only have access to the minimum functionality required for their roles. Additionally, regular security awareness training should be provided to personnel who may be targeted by social engineering attacks that could exploit this vulnerability, as the requirement for human interaction suggests that user behavior plays a role in successful exploitation. Organizations should also establish incident response procedures specifically addressing this vulnerability to ensure rapid response and containment in case of successful exploitation attempts.
