CVE-2026-101451 in Siebel Life Sciences
Summary
by MITRE • 10/21/2026
Vulnerability in the Siebel Life Sciences product of Oracle Siebel CRM (component: Web UI). Supported versions that are affected are 17.0-26.9. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Siebel Life Sciences. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Siebel Life Sciences, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Siebel Life Sciences accessible data as well as unauthorized access to critical data or complete access to all Siebel Life Sciences accessible data. CVSS 3.1 Base Score 8.7 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N).

The identified vulnerability resides within the Web UI component of Oracle Siebel Life Sciences, a specialized module of the broader Oracle Siebel CRM suite designed for pharmaceutical and life sciences industries. This security flaw affects supported versions ranging from 17.0 through 26.9, indicating that it is present in multiple iterations of the software rather than being isolated to a single release cycle. The vulnerability classifies as an easily exploitable issue, which significantly lowers the barrier for entry for potential adversaries. While the technical root cause lies within Siebel Life Sciences, the operational impact extends beyond this specific module due to scope changes that allow attacks to compromise additional products integrated with or accessible from the affected system. This lateral movement capability amplifies the risk profile considerably, as a breach in one area can cascade into broader organizational systems, potentially exposing sensitive data across multiple enterprise applications rather than being contained within the life sciences workflow alone.
From a technical perspective, the vulnerability allows for unauthorized creation, deletion, or modification of critical data, as well as complete access to all Siebel Life Sciences accessible data. This behavior is characteristic of an Insecure Direct Object Reference (IDOR) or Broken Access Control flaw, where the application fails to properly verify that the authenticated user has permission to perform actions on specific resources identified by their unique identifiers. The attack vector requires network access via HTTP and low privileged attacker status, meaning that individuals with basic login credentials can exploit this weakness without needing administrative rights. However, a critical constraint in the exploitation chain is the requirement for human interaction from a person other than the attacker. This suggests the vulnerability may involve social engineering elements or require the victim to perform an action such as clicking a malicious link or confirming a deceptive prompt within the web interface. Despite this user involvement requirement, the ease of exploitation and low privilege threshold make it a high-risk threat in environments where users are not adequately trained in security awareness.
The operational impact of successfully exploiting this vulnerability is severe, aligning with a CVSS 3.1 Base Score of 8.7, which denotes High severity. The primary impacts are on Confidentiality and Integrity, as indicated by the vector components C:H and I:H, while Availability remains unaffected (A:N). This means that attackers can exfiltrate sensitive patient or clinical trial data, leading to significant regulatory compliance violations under frameworks such as HIPAA or GDPR if personal health information is involved. Furthermore, the ability to modify critical data poses a direct threat to business continuity and decision-making integrity. In life sciences contexts, tampering with research data, drug interaction records, or supply chain logistics could have catastrophic real-world consequences beyond digital security breaches. The scope change aspect further complicates incident response, as remediation efforts must address not just the Siebel Life Sciences component but also any interconnected systems that rely on its data integrity and access controls.
Mitigation strategies should prioritize immediate patching to the latest supported version of Oracle Siebel CRM if available, ensuring all security updates related to Web UI vulnerabilities are applied. In cases where patching is delayed due to operational constraints, network segmentation becomes critical; restricting HTTP traffic to the vulnerable component from untrusted networks and enforcing strict access control lists can limit exposure. Implementing robust input validation on the server side for all object references handled by the web interface will address the root cause of unauthorized data manipulation. Additionally, deploying Web Application Firewalls with rulesets tuned to detect IDOR patterns or abnormal data modification requests can provide a layer of defense in depth. Security awareness training is also essential given the human interaction requirement; users must be educated on recognizing suspicious prompts that could facilitate exploitation. Regular audits of access control policies and privilege assignments will help ensure that low-privileged accounts do not possess excessive permissions over critical resources, thereby reducing the attack surface for this specific vulnerability class mapped to CWE-639 in industry standards.
