Description
Vulnerability in the Siebel CRM Integration product of Oracle Siebel CRM (component: EAI). Supported versions that are affected are 17.0-26.9. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Siebel CRM Integration. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Siebel CRM Integration, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Siebel CRM Integration accessible data as well as unauthorized update, insert or delete access to some of Siebel CRM Integration accessible data. CVSS 3.1 Base Score 6.9 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:L/A:N).

AI Analysis

Impact

The vulnerability lies in the Siebel CRM Integration’s HTTP endpoints, which lack proper authentication, allowing an unauthenticated attacker to read or modify critical data. This results in confidentiality loss and integrity compromise, matching CWE-200. Successful exploitation grants the attacker unrestricted access to all data exposed by the integration and can extend to other connected products due to the scope change noted in the advisory.

Affected Systems

Oracle Siebel CRM Integration, versions 17.0 through 26.9, is the sole product cited as affected. The impact may cascade to additional products that interact with the integration because of a scope change.

Risk and Exploitability

The CVSS 3.1 base score of 6.9 indicates moderate severity, while the EPSS score of less than 1% suggests a low likelihood of widespread exploitation. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires unauthenticated HTTP access and a separate human user at the target, reducing immediate remote attack feasibility but still posing a medium‑to‑high threat for organizations with exposed integration endpoints. The risk is elevated for systems that host the integration and expose its endpoints to the network.
