CVE-2017-3330 in Siebel CRM
Summary
by MITRE
Vulnerability in the Siebel UI Framework component of Oracle Siebel CRM (subcomponent: Open UI). The supported version that is affected is 16.1. Easily exploitable vulnerability allows low privileged 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 access to critical data or complete access to all Siebel UI Framework accessible data as well as unauthorized update, insert or delete access to some of Siebel UI Framework accessible data. CVSS v3.0 Base Score 7.6 (Confidentiality and Integrity impacts).

The vulnerability identified as CVE-2017-3330 resides within the Siebel UI Framework component of Oracle Siebel CRM, specifically within the Open UI subcomponent version 16.1. This represents a significant security weakness that affects the core user interface framework governing how Siebel applications present data and functionality to end users. The affected system operates as a comprehensive customer relationship management platform that handles sensitive business data, making this vulnerability particularly concerning from a cybersecurity perspective. The vulnerability's classification as easily exploitable indicates that malicious actors require minimal technical expertise to leverage this weakness effectively.
This security flaw manifests as a privilege escalation vulnerability that operates through HTTP network connections, allowing attackers with low privilege levels to compromise the Siebel UI Framework component. The technical nature of this vulnerability involves insufficient access controls within the Open UI framework, which permits unauthorized users to gain access to data and functionality beyond their normal operational scope. The attack vector specifically requires network access via HTTP, making it accessible through standard web protocols without requiring specialized tools or deep technical knowledge. The vulnerability's impact extends beyond just the immediate Siebel UI Framework component, potentially affecting additional products within the Oracle Siebel ecosystem that rely on the same underlying framework components.
The operational impact of this vulnerability is substantial and multifaceted, as successful exploitation can lead to unauthorized access to critical data within the Siebel environment. Attackers can potentially gain complete access to all data accessible through the Siebel UI Framework, including sensitive customer information, business records, and operational data. The vulnerability also permits unauthorized modification capabilities, allowing attackers to insert, update, or delete data within the system. This comprehensive access control bypass represents a severe compromise of both confidentiality and integrity principles, as defined by the CVSS v3.0 base score of 7.6. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted user manipulation may be necessary to complete the exploitation process, though the underlying technical vulnerability remains easily accessible.
The vulnerability's classification aligns with CWE-284 Access Control Issues, which specifically addresses inadequate access controls that allow unauthorized users to access protected resources. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and credential access, particularly T1078 Valid Accounts and T1068 Exploitation for Privilege Escalation. Organizations affected by this vulnerability should implement immediate mitigations including network segmentation to limit access to Siebel applications, implementing robust authentication controls, and applying the relevant Oracle security patches. The vulnerability demonstrates the critical importance of maintaining up-to-date security controls within enterprise CRM systems, as these platforms often contain highly sensitive business information and serve as potential entry points for broader network infiltration attempts. Additionally, organizations should conduct comprehensive security assessments of their Siebel environments to identify any additional vulnerabilities that may compound the risks associated with this particular flaw.
