DescriptionCVE.org

Vulnerability in the Oracle Commerce Platform product of Oracle Commerce (component: Dynamo Application Framework). The supported version that is affected is 11.4.0. Difficult to exploit vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Commerce Platform executes to compromise Oracle Commerce Platform. Successful attacks of this vulnerability can result in takeover of Oracle Commerce Platform. CVSS 3.1 Base Score 7.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).

AnalysisAI

Full platform takeover is possible in Oracle Commerce Platform 11.4.0 via the Dynamo Application Framework component, exploitable by an unauthenticated attacker who can reach the adjacent network segment hosting the server. The CVSS vector (AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) confirms that successful exploitation yields complete compromise of confidentiality, integrity, and availability - consistent with Oracle's characterization of 'takeover.' No public exploit code has been identified at time of analysis, and this CVE does not appear on the CISA KEV catalog.
