CVE-2019-3024 in Installed Base
Summary
by MITRE
Vulnerability in the Oracle Installed Base product of Oracle E-Business Suite (component: Engineering Change Order). Supported versions that are affected are 12.2.3-12.2.9. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Installed Base. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Installed Base, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Installed Base accessible data. CVSS 3.0 Base Score 4.7 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N).

The vulnerability identified as CVE-2019-3024 resides within Oracle E-Business Suite's Installed Base component, specifically within the Engineering Change Order functionality. This represents a critical security weakness that affects Oracle EBS versions 12.2.3 through 12.2.9, making it a widespread concern across numerous enterprise deployments. The vulnerability stems from inadequate input validation and access control mechanisms within the web application layer, creating an exploitable pathway for malicious actors to manipulate the system's data integrity. The affected component processes engineering change orders which are fundamental to managing product configurations and modifications within enterprise environments.
The technical flaw manifests as a lack of proper authentication and authorization checks when processing HTTP requests through the Installed Base web interface. An unauthenticated attacker can leverage this weakness to perform unauthorized operations against the system's data repository. The vulnerability requires minimal technical skill to exploit, as indicated by the CVSS 3.0 base score of 4.7, and can be executed through standard network-based HTTP communications. The attack vector operates over the network (AV:N) with low access complexity (AC:L) and no privilege requirements (PR:N), making it particularly dangerous for organizations that expose their EBS instances to external networks. The requirement for human interaction (UI:R) suggests that while the initial exploitation might require user involvement, the underlying flaw remains persistent and can be repeatedly leveraged.
The operational impact of this vulnerability extends beyond the immediate compromise of Installed Base data, as it can potentially affect interconnected Oracle EBS modules and systems. Attackers can achieve unauthorized update, insert, or delete operations on sensitive data, which could lead to significant business disruption and data corruption. The integrity impact (C:N/I:L/A:N) indicates that while the attacker cannot directly access data (confidentiality not impacted) or cause system availability issues, they can modify critical configuration data that affects product engineering processes. This could result in unauthorized product modifications, incorrect engineering change tracking, or manipulation of installed base records that directly impact inventory management, product development, and manufacturing processes. The scalability of the impact (S:C) demonstrates that a successful attack could potentially cascade through multiple dependent systems within the Oracle EBS ecosystem.
Organizations should implement immediate mitigations including network segmentation to restrict access to EBS instances, deployment of web application firewalls to monitor and filter HTTP traffic, and implementation of strict access controls for the affected components. The vulnerability aligns with CWE-287 (Improper Authentication) and CWE-311 (Missing Encryption of Sensitive Data) categories, reflecting fundamental security design flaws that require comprehensive remediation. From an ATT&CK framework perspective, this vulnerability maps to techniques involving T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) where attackers can leverage HTTP protocols to execute unauthorized data modifications. Patch management should be prioritized immediately, with organizations upgrading to Oracle EBS versions that have addressed this vulnerability. Additionally, monitoring for suspicious HTTP requests and implementing automated alerting for unauthorized data modifications will help detect potential exploitation attempts. The vulnerability demonstrates the critical importance of maintaining up-to-date security patches in enterprise environments, as the exploitation of such flaws can have cascading effects on business operations and data integrity across multiple organizational systems.
