Technical details
This local privilege escalation vulnerability in Oracle Siebel CRM's Server Infrastructure component (versions 17.0–26.7) requires the attacker to have low-level logon privileges and local access to the infrastructure where Siebel CRM Deployment executes. The vulnerability is easily exploitable and requires no user interaction or elevated initial privileges. Successful exploitation allows an attacker to achieve complete compromise of the Siebel CRM Deployment system, gaining unauthorized control over confidentiality, integrity, and availability of CRM data and services. Patches are expected from Oracle as part of their regular security release cycle.
