DescriptionCVE.org
Vulnerability in the Siebel CRM Cloud Applications product of Oracle Siebel CRM (component: Siebel Cloud Manager). Supported versions that are affected are 22.3-26.5. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Siebel CRM Cloud Applications. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Siebel CRM Cloud Applications accessible data as well as unauthorized update, insert or delete access to some of Siebel CRM Cloud Applications accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Siebel CRM Cloud Applications. CVSS 3.1 Base Score 7.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L).
Executive ViewAI
Oracle Siebel CRM Cloud Manager (versions 22.3-26.5) contains an unauthenticated remote vulnerability allowing attackers to access customer data and modify records. No vendor patch is currently available, creating ongoing exposure for organizations running these versions. Without immediate compensating controls, companies face material risk of customer data exfiltration from their core CRM system.
Within 24 hours, identify all Siebel Cloud environments and confirm versions in use (22.3-26.5 scope); review access logs for suspicious activity and data access patterns. Within 7 days, implement network segmentation and WAF rules to restrict Siebel Cloud access, enable enhanced monitoring for anomalous API activity, and contact Oracle for patch availability timeline and interim guidance. Within 30 days, evaluate upgrade paths to versions outside the vulnerable range, prioritize remediation for instances handling sensitive customer data, and establish a patching schedule once vendor updates become available.
No vendor-released patch identified at time of analysis. Interim mitigations: restrict network access to Siebel Cloud instances using firewall and WAF rules; implement continuous monitoring for unusual data access and export patterns; review and minimize external API exposure; escalate patch urgency to Oracle support; consider disabling non-essential instances until patches are released.

Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
