  - Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent:
    Security). Supported versions that are affected are Java SE: 6u181, 7u161 and 8u152; Java SE Embedded:
    8u152; JRockit: R28.3.17. Difficult to exploit vulnerability allows unauthenticated attacker with network
    access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this
    vulnerability can result in unauthorized creation, deletion or modification access to critical data or all
    Java SE, Java SE Embedded, JRockit accessible data as well as unauthorized access to critical data or
    complete access to all Java SE, Java SE Embedded, JRockit accessible data. Note: Applies to client and
    server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start
    applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the
    specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as
    through a web service. (CVE-2018-2783)

Note that Nessus relies on the presence of the package as reported by the vendor.");
