CVE-2017-10263 in Siebel UI Framework
Summary
by MITRE
Vulnerability in the Siebel UI Framework component of Oracle Siebel CRM (subcomponent: UIF Open UI). Supported versions that are affected are 16.0 and 17.0. 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 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 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-2017-10263 resides within the Siebel UI Framework component of Oracle Siebel CRM, specifically affecting the UIF Open UI subcomponent. This security flaw impacts versions 16.0 and 17.0 of the Siebel CRM platform, representing a significant threat to enterprise organizations that rely on this customer relationship management system. The vulnerability operates within the context of a web-based interface where users interact with the Siebel application through standard HTTP protocols, making it accessible to attackers who can reach the system over network connections without requiring authentication credentials.
The technical implementation of this vulnerability stems from inadequate input validation and access control mechanisms within the Siebel UI Framework. Attackers can exploit this weakness by crafting malicious HTTP requests that bypass normal authentication procedures and gain unauthorized access to sensitive data within the system. The flaw allows for unauthorized access to critical data and provides attackers with the ability to modify, insert, or delete information within the Siebel UI Framework accessible data stores. This represents a fundamental breakdown in the application's security model where the system fails to properly validate user inputs and maintain proper authorization boundaries.
The operational impact of CVE-2017-10263 extends beyond the immediate compromise of the Siebel UI Framework itself. The vulnerability's classification as easily exploitable means that attackers can potentially leverage this flaw to gain significant access to enterprise data without requiring specialized tools or extensive technical knowledge. The CVSS 3.0 score of 8.2 indicates a high severity threat with confidentiality and integrity impacts, where the attacker can access critical data and potentially modify system information. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted phishing campaigns may be necessary to initially exploit the vulnerability, though once the initial access point is established, the attacker can operate with significant privileges.
Organizations affected by this vulnerability face substantial risks including data breaches, unauthorized modifications to customer information, and potential disruption of business operations. The compromise of Siebel CRM systems can have cascading effects throughout an organization's customer management processes, potentially leading to loss of customer trust and regulatory compliance violations. The vulnerability's ability to impact additional products demonstrates how security flaws in one component can create broader systemic risks within enterprise applications. According to CWE classification, this vulnerability relates to improper input validation and insufficient authorization controls, which are fundamental security weaknesses that frequently appear in web applications and enterprise software platforms.
Mitigation strategies for CVE-2017-10263 should include immediate implementation of Oracle security patches and updates for affected versions 16.0 and 17.0 of Siebel CRM. Organizations should also implement network segmentation to limit access to Siebel applications, deploy web application firewalls to monitor and filter HTTP traffic, and establish robust monitoring procedures to detect suspicious activities. The ATT&CK framework categorizes this type of vulnerability under privilege escalation and credential access techniques, making it essential for organizations to implement comprehensive security monitoring and incident response procedures. Additionally, regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other enterprise applications and ensure that access controls remain effective against evolving threat landscapes.
