Technical details
This vulnerability in the Siebel CRM Deployment Server Infrastructure component is easily exploitable and allows a low-privileged attacker with network access via HTTPS to achieve complete system compromise. The attack requires minimal preconditions—only a low-privilege account and network reachability—and does not require user interaction. Successful exploitation results in full takeover of the Siebel CRM Deployment, granting the attacker unrestricted access to confidentiality, integrity, and availability of the system and data. The vulnerability affects versions 17.0 through 26.7; patch availability should be confirmed with Oracle.
