AI Analysis

Impact

The vulnerability in Oracle Siebel CRM Deployment’s Server Infrastructure enables low‑privileged attackers to access the system over HTTP and perform unauthorized creation, deletion, and modification of critical data, gain unrestricted access to all data available through the deployment, and induce a partial denial of service. The flaw affects all supported releases from version 17.0 through 26.9.

Affected Systems

Oracle Siebel CRM Deployment; all supported versions 17.0 through 26.9 are affected.

Risk and Exploitability

The CVSS v3.1 base score of 8.3 indicates major confidentiality, integrity, and moderate availability impact. The EPSS score of < 1 % suggests a very low probability of exploitation.
