CVE-2019-2907 in Web Services
Summary
by MITRE
Vulnerability in the Oracle Web Services product of Oracle Fusion Middleware (component: SOAP with Attachments API for Java). The supported version that is affected is 12.2.1.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Web Services. While the vulnerability is in Oracle Web Services, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Web Services accessible data as well as unauthorized read access to a subset of Oracle Web Services accessible data. CVSS 3.0 Base Score 7.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2019-2907 resides within Oracle Web Services component of Oracle Fusion Middleware, specifically affecting the SOAP with Attachments API for Java implementation in version 12.2.1.3.0. This flaw represents a critical security weakness that operates at the intersection of web service communication protocols and application layer security. The vulnerability manifests as a remote code execution vector that can be exploited without requiring authentication, making it particularly dangerous for environments where Oracle Web Services operates in exposed network configurations. The attack surface is expanded through the component's integration with broader Oracle Fusion Middleware ecosystem, potentially allowing adversaries to leverage this weakness to compromise additional Oracle products that share underlying infrastructure or communication protocols.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the SOAP with Attachments API implementation. Attackers can exploit this weakness through HTTP network connections without requiring any authentication credentials, leveraging the SOAP protocol's attachment handling capabilities to execute malicious payloads. The vulnerability's classification as easily exploitable indicates that the attack vector requires minimal technical sophistication and can be automated, making it attractive to both targeted and opportunistic threat actors. The flaw essentially allows unauthorized modification of data through update, insert, and delete operations while simultaneously enabling read access to sensitive information within the affected system's data scope.
The operational impact of CVE-2019-2907 extends beyond the immediate Oracle Web Services component, creating cascading security implications throughout Oracle Fusion Middleware environments. Successful exploitation can result in data integrity compromise, allowing attackers to modify or delete critical business data, while also enabling unauthorized data exfiltration. The CVSS 3.0 score of 7.2 reflects the moderate to high severity of this vulnerability, with confidentiality and integrity impacts rated as low to moderate but still significant given the potential for data manipulation. The vulnerability's potential to affect additional products aligns with ATT&CK technique T1210 for exploitation of remote services and T1071.004 for application layer protocol usage, demonstrating how a single vulnerability can serve as a foothold for broader system compromise.
Organizations affected by this vulnerability should implement immediate mitigations including network segmentation to limit exposure of Oracle Web Services to untrusted networks, applying Oracle's security patches as soon as they become available, and implementing robust network monitoring to detect anomalous SOAP protocol traffic patterns. The vulnerability's characteristics align with CWE-284 (Improper Access Control) and CWE-345 (Insufficient Verification of Data Authenticity), emphasizing the need for proper input validation and access control enforcement. Security teams should also consider implementing Web Application Firewall rules to filter suspicious SOAP requests and establish comprehensive incident response procedures that account for potential data integrity violations and unauthorized access scenarios. The CVSS vector indicates that this vulnerability operates with network access requirements but minimal attack complexity, making it essential for organizations to prioritize remediation efforts and monitor for exploitation attempts in their production environments.
