CVE-2018-3059 in Siebel CRM
Summary
by MITRE
Vulnerability in the Siebel UI Framework component of Oracle Siebel CRM (subcomponent: UIF Open UI). Supported versions that are affected are 18.7, 18.8 and 18.9. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Siebel UI Framework. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Siebel UI Framework, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Siebel UI Framework accessible data as well as unauthorized read access to a subset of Siebel UI Framework accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2018-3059 resides within the Siebel UI Framework component of Oracle Siebel CRM, specifically affecting the UIF Open UI subcomponent. This security flaw impacts versions 18.7, 18.8, and 18.9 of the Siebel CRM platform, representing a significant concern for organizations relying on this enterprise customer relationship management solution. The vulnerability operates at the application layer and manifests through the HTTP protocol, creating an attack surface that can be exploited by unauthenticated remote adversaries without requiring any prior authentication credentials or privileged access.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Siebel UI Framework's Open UI implementation. The flaw allows attackers to perform unauthorized operations against the framework's data access controls, enabling them to execute unauthorized update, insert, or delete operations on sensitive data within the affected system. Additionally, the vulnerability permits unauthorized read access to specific subsets of data that should otherwise be protected. The CVSS 3.0 scoring of 6.1 indicates a medium severity vulnerability with confidentiality and integrity impacts, where the attack requires low complexity but necessitates user interaction from someone other than the attacker. This requirement for human interaction suggests the vulnerability may be exploited through social engineering or phishing techniques that trick users into performing actions that trigger the malicious code execution.
The operational impact of this vulnerability extends beyond the immediate Siebel UI Framework component, as successful exploitation can potentially affect additional products within the Siebel CRM ecosystem. This cascading effect demonstrates the interconnected nature of enterprise applications and highlights how a single vulnerability in a core framework component can compromise broader organizational data integrity and confidentiality. The vulnerability's classification under CWE-284 (Improper Access Control) and its alignment with ATT&CK technique T1078 (Valid Accounts) indicates that attackers can leverage this flaw to establish persistent access patterns while maintaining operational stealth. Organizations may face significant data exposure risks, including potential modification of customer records, transactional data manipulation, and unauthorized access to proprietary business information.
Mitigation strategies for CVE-2018-3059 should prioritize immediate patch application from Oracle, as this represents the most effective remediation approach for addressing the underlying access control weaknesses. Network segmentation and firewall rules should be implemented to restrict HTTP access to Siebel CRM components, particularly limiting access to only trusted administrative networks. Additional defensive measures include implementing robust input validation controls, enabling comprehensive audit logging for all framework operations, and conducting regular security assessments to identify potential exploitation vectors. Organizations should also consider implementing privileged access management solutions and establishing strict user access controls to minimize the potential impact of successful exploitation attempts. The vulnerability's characteristics align with ATT&CK tactic TA0006 (Credential Access) and TA0008 (Lateral Movement), emphasizing the need for layered security approaches that address both perimeter defense and internal access controls to prevent unauthorized data manipulation and exfiltration activities.
