Summary
Vulnerability in the Oracle Solaris product of Oracle Systems (component: Plugins) affecting version 11.4. A high privileged attacker with local logon can exploit it with human interaction to gain unauthorized creation, deletion or modification access to critical data and complete access to all accessible data, with scope change impacting additional products.
Risk Assessment
Exploitation can compromise confidentiality and integrity of critical data and affect additional products.
Recommendation
Apply the Oracle patch for Oracle Solaris 11.4 and restrict installation and execution of untrusted plugins.

Original NVD description (English source)
Vulnerability in the Oracle Solaris product of Oracle Systems (component: Plugins). The supported version that is affected is 11.4. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle Solaris executes to compromise Oracle Solaris. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Solaris, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Solaris accessible data as well as unauthorized access to critical data or complete access to all Oracle Solaris accessible data. CVSS 3.1 Base Score 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:N).
