CVE-2019-2828 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle Field Service component of Oracle E-Business Suite (subcomponent: Wireless). Supported versions that are affected are 12.1.1 - 12.1.3 and 12.2.3 - 12.2.8. 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 takeover of Oracle Field Service. CVSS 3.0 Base Score 9.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H).

The vulnerability identified as CVE-2019-2828 represents a critical security flaw within Oracle Field Service component of the Oracle E-Business Suite ecosystem, specifically affecting the Wireless subcomponent. This vulnerability exists in multiple version ranges including 12.1.1 through 12.1.3 and 12.2.3 through 12.2.8, indicating a widespread impact across several generations of the Oracle E-Business Suite. The flaw manifests as an easily exploitable condition that permits unauthenticated attackers to compromise the targeted system through standard HTTP network connections, making it particularly dangerous in environments where network exposure is inevitable. The vulnerability's classification as CVSS 3.0 Base Score 9.6 demonstrates its severe impact potential across all three core security principles of confidentiality, integrity, and availability, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H indicating network-based access with low attack complexity, no privilege requirements, and requiring human interaction but potentially affecting additional products beyond the primary target.
The technical exploitation of this vulnerability involves leveraging weaknesses in the wireless communication protocols or interfaces within Oracle Field Service that allow unauthorized access without proper authentication mechanisms. This type of vulnerability typically stems from inadequate input validation, improper access controls, or flawed session management within the wireless component that processes field service requests and communications. The requirement for human interaction suggests that while the initial exploitation may be automated, some form of user involvement or specific conditions must be met for the attack to succeed, potentially involving social engineering or targeted user actions that trigger the vulnerable code path. The security implications extend beyond the immediate field service component as indicated by the CVSS score S:C, meaning that successful exploitation can impact additional products within the Oracle ecosystem, creating cascading security consequences that may affect other interconnected systems.
The operational impact of CVE-2019-2828 is substantial given its high CVSS score and the critical nature of field service operations within enterprise environments. An attacker who successfully exploits this vulnerability could gain complete control over the Oracle Field Service functionality, potentially allowing them to manipulate field service data, disrupt operations, access sensitive customer information, or even use the compromised system as a pivot point for attacking other systems within the enterprise network. The confidentiality, integrity, and availability impacts are all rated as high, meaning that attackers could potentially read sensitive data, modify critical field service records, or completely disable the service functionality. Organizations using affected Oracle Field Service versions face significant risk of operational disruption, data breaches, and potential regulatory compliance violations, particularly in industries where field service operations are critical to business continuity and customer satisfaction.
Mitigation strategies for CVE-2019-2828 should prioritize immediate patch application from Oracle, as this represents the most effective defense against the vulnerability. Organizations should also implement network segmentation and access controls to limit exposure of the affected Oracle Field Service components to untrusted networks, utilizing firewalls and intrusion detection systems to monitor for suspicious HTTP traffic patterns. Additional defensive measures include implementing strong authentication mechanisms, regularly monitoring system logs for unauthorized access attempts, and conducting thorough security assessments of the wireless components within Oracle Field Service. The vulnerability aligns with CWE-287 which addresses improper authentication issues, and may map to ATT&CK techniques involving privilege escalation and lateral movement within enterprise networks, particularly T1078 for valid accounts and T1021 for remote services. Organizations should also consider implementing network monitoring solutions that can detect anomalous behavior patterns consistent with exploitation attempts and maintain comprehensive incident response procedures specifically addressing Oracle E-Business Suite vulnerabilities to ensure rapid containment and remediation of any successful exploitation attempts.
