Critical Nessus Plugin ID 61681

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 9.5

Synopsis

The remote Windows host contains a programming platform that is affected by multiple vulnerabilities.

Description

The version of Oracle (formerly Sun) Java SE or Java for Business installed on the remote host is earlier than 7 Update 7 and is, therefore, potentially affected the following vulnerabilities :

- The 'getField' method in the 'sun.awt.SunToolkit class' provided by the bundled SunToolkit can be used to obtain any field of a class - even private fields.
This error can allow privilege escalation.
(CVE-2012-0547)

- Two unspecified remote code execution vulnerabilities exist related to the 'com.sun.beans.finder.ConstructorFinder' and 'com.sun.beans.finder.FieldFinder' methods. No further details have been provided. (CVE-2012-1682, CVE-2012-3136)

- The 'setField' method provided by the bundled SunToolkit can be used to execute a privileged operation and calls 'setAccessible(true)' on the returned field reference, allowing an attacker to disable any 'final' or 'private' directives and gain full control to run code in the Java virtual machine. (CVE-2012-4681)

Note that at least one of these vulnerabilities is currently being exploited in the wild.

Solution

Upgrade to JDK / JRE 7 Update 7 or later, and remove, if necessary, any affected versions.
