Vulnerability in the Siebel CRM Deployment product of Oracle Siebel CRM (component: Application Interface). Supported versions that are affected are 17.0-26.6. Easily exploitable vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Siebel CRM Deployment executes to compromise Siebel CRM Deployment. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Siebel CRM Deployment accessible data as well as unauthorized access to critical data or complete access to all Siebel CRM Deployment accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Oracle Siebel CRM Deployment's Application Interface component (versions 17.0 through 26.6) exposes complete read and write access to all CRM data to unauthenticated attackers positioned on the adjacent network segment. The CVSS vector confirms zero authentication requirements and low attack complexity, meaning any actor with access to the physical communication segment hosting the Siebel server can silently exfiltrate or corrupt the entire CRM dataset. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be present on the physical communication segment (Layer 2 network - LAN, VLAN, or equivalent) directly attached to the hardware running Siebel CRM Deployment; this is the defining constraint specified by AV:A in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 8.1 (High) is justified by PR:N (no credentials required), AC:L (low attack complexity), and dual high impacts on confidentiality and integrity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Oracle Critical Security Patch Update released in August 2026, available from Oracle's advisory at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
