## Technical details

This is a privilege escalation vulnerability in the Server Infrastructure component of Oracle Siebel CRM Deployment (versions 17.0–26.7). The vulnerability requires an attacker to have high-level privileges and network access via HTTP; no special preconditions or user interaction are needed beyond these. Successful exploitation allows a high-privileged attacker to achieve complete system compromise with scope change, affecting confidentiality, integrity, and availability across Siebel CRM Deployment and potentially related products. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H) reflects network accessibility and high complexity with high-privilege requirements.
