# Oracle Solaris 11.4 Plugins flaw lets privileged local user compromise system

A flaw in the Plugins component of Oracle Solaris 11.4 lets an attacker who already has high-privilege logon to the system compromise Solaris. A successful attack needs a second person to take an action and can change or read critical data, and the scope change means other products may also be affected.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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).
