CVE-2019-2665 in Common Applications
Summary
by MITRE
Vulnerability in the Oracle Common Applications component of Oracle E-Business Suite (subcomponent: CRM User Management Framework). Supported versions that are affected are 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6, 12.2.7 and 12.2.8. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Common Applications. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Common Applications, 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 Common Applications accessible data as well as unauthorized update, insert or delete access to some of Oracle Common Applications 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-2019-2665 resides within the Oracle Common Applications component of Oracle E-Business Suite, specifically within the CRM User Management Framework subcomponent. This security flaw affects multiple versions including 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6, 12.2.7, and 12.2.8, representing a significant attack surface across the Oracle E-Business Suite ecosystem. The vulnerability's classification as easily exploitable indicates that attackers can leverage it with minimal technical sophistication, making it particularly dangerous in production environments where such systems often contain sensitive business data and critical operational information.
The technical nature of this vulnerability allows an unauthenticated attacker to compromise Oracle Common Applications through network access via HTTP protocols. This means that malicious actors can exploit the flaw without requiring valid credentials or prior access to the system, which significantly increases the attack surface and potential impact. The vulnerability requires human interaction from users other than the attacker, suggesting that social engineering or targeted phishing campaigns might be necessary to facilitate exploitation. However, the underlying flaw itself creates an accessible entry point that can be leveraged by attackers with basic network connectivity to the affected systems.
From an operational impact perspective, successful exploitation of this vulnerability can result in unauthorized access to critical data within Oracle Common Applications, potentially exposing sensitive customer information, financial records, and business intelligence. The CVSS 3.0 base score of 8.2 reflects the severity of the impact, with high confidentiality impact and low integrity impact, indicating that data theft poses the primary concern while modification capabilities are more limited. The vulnerability's potential to compromise complete access to all Oracle Common Applications accessible data means that attackers could potentially gain visibility into extensive business operations, customer relationships, and internal processes managed through the E-Business Suite. Additionally, unauthorized update, insert, or delete access to some data could lead to data corruption, manipulation, or complete data loss in affected systems.
The security implications extend beyond the immediate Oracle Common Applications component, as attacks may significantly impact additional products within the Oracle E-Business Suite ecosystem. This cascading effect means that exploitation of this vulnerability could potentially compromise other integrated Oracle applications, creating a broader attack surface and increasing the potential for business disruption. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) clearly indicates that network-based attacks require low access complexity, no privilege requirements, and human interaction, while the scope change (S:C) suggests that the vulnerability could affect additional products beyond the directly targeted component. This vulnerability aligns with CWE-287 (Improper Authentication) and potentially CWE-352 (Cross-Site Request Forgery) categories, representing a fundamental breakdown in authentication mechanisms that allows unauthorized access to protected resources.
Organizations should implement immediate mitigations including applying the relevant Oracle patches and updates, implementing network segmentation to limit access to affected systems, and monitoring network traffic for suspicious HTTP requests targeting the vulnerable CRM User Management Framework. Access controls should be strengthened through firewall rules that restrict access to Oracle E-Business Suite components, while security monitoring solutions should be configured to detect and alert on anomalous access patterns. Additionally, organizations should conduct comprehensive vulnerability assessments to identify all instances of affected Oracle E-Business Suite versions and ensure that all users receive security awareness training to recognize potential social engineering attempts that could facilitate exploitation of this vulnerability. The ATT&CK framework would categorize this vulnerability under T1190 (Exploit Public-Facing Application) and potentially T1071.004 (Application Layer Protocol: DNS) if exploitation involves DNS-based reconnaissance or command and control communications.
