CVE-2026-47032 in Siebel CRM End User
Summary
by MITRE • 07/22/2026
Vulnerability in the Siebel CRM End User product of Oracle Siebel CRM (component: Redwood UI). Supported versions that are affected are 24.4-26.3. Difficult to exploit vulnerability allows high privileged attacker with network access via HTTP to compromise Siebel CRM End User. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Siebel CRM End User, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Siebel CRM End User. CVSS 3.1 Base Score 2.6 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:N/A:L).

This vulnerability resides within Oracle Siebel CRM's End User component, specifically within the Redwood UI framework which serves as the modern user interface layer for the enterprise customer relationship management platform. The affected versions span from 24.4 through 26.3, indicating a substantial release range that would impact organizations using these particular Siebel CRM iterations. The vulnerability classification as difficult to exploit suggests that while the attack vector is technically achievable, it requires specific conditions and circumstances that make successful exploitation less straightforward than more severe vulnerabilities.
The security flaw manifests as a privilege escalation issue that allows a high-privileged attacker with network access via HTTP protocol to compromise the Siebel CRM End User environment. This represents a significant concern because the attacker must already possess elevated privileges within the system, yet the vulnerability enables further exploitation capabilities. The CVSS 3.1 scoring of 2.6 with a vector of AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:N/A:L indicates that while the attack requires high privileges and human interaction, the scope change aspect introduces additional risk as impacts may extend beyond the primary target to other connected systems.
The technical implementation of this vulnerability appears to involve an insufficient authorization mechanism within the Redwood UI framework that fails to properly validate access controls for certain operations. The partial denial of service condition suggests that successful exploitation could disrupt normal operational workflows within Siebel CRM End User, potentially affecting user access and system functionality without completely rendering the application unusable. This aligns with CWE-285 which addresses improper authorization issues in software systems.
The requirement for human interaction from a person other than the attacker indicates that this vulnerability likely involves user-facing interfaces or interactive processes that require legitimate user engagement to execute malicious code or manipulate system behavior. The scope change aspect of the vulnerability demonstrates how security incidents can cascade beyond initial targets, suggesting that exploitation may enable access to additional components within the broader Siebel CRM ecosystem or connected applications. This characteristic aligns with ATT&CK technique T1078 which covers legitimate credentials and privilege escalation tactics.
Organizations should implement immediate mitigations including reviewing and tightening HTTP access controls, monitoring for unusual network activity patterns, and ensuring that user interaction requirements are properly enforced through additional validation layers. The vulnerability's classification as a partial denial of service indicates that organizations should also prepare incident response procedures to address potential disruptions in CRM operations. Regular security assessments of the Redwood UI framework should be conducted to identify similar authorization gaps, with particular attention to how different system components interact and share access controls.
The attack vector through HTTP access points requires network-level security measures including proper firewall configurations, web application firewalls, and monitoring solutions that can detect anomalous HTTP traffic patterns. Organizations implementing Siebel CRM End User within their infrastructure should consider upgrading to patched versions as soon as available, while simultaneously evaluating their overall security posture regarding privileged access and user interaction controls. The vulnerability's scope change characteristic emphasizes the importance of maintaining comprehensive network segmentation and access control policies to limit potential lateral movement and cascading impacts across interconnected enterprise systems.
This vulnerability represents a concerning example of how modern enterprise applications can contain authorization flaws that, while not immediately catastrophic, create opportunities for significant operational disruption and potential escalation to more severe security incidents. The combination of high privileges required, network accessibility via HTTP, and scope change characteristics indicates that organizations should approach this vulnerability with careful consideration of their existing security controls and incident response readiness. Proper patch management strategies, user access reviews, and continuous monitoring protocols will be essential components in defending against exploitation attempts targeting this specific authorization weakness within the Siebel CRM End User environment.
The technical implications extend beyond simple service disruption to include potential data integrity concerns and operational availability impacts that could affect customer relationship management processes critical to business operations. Organizations should also consider implementing additional authentication layers and access validation mechanisms to prevent unauthorized access to privileged functions within the Redwood UI framework, particularly as this vulnerability demonstrates how seemingly isolated components can create broader security impact through scope change characteristics.
