Oracle Java JDK / JRE 6 < Update 35 SunToolKit getField() and getMethod() Access Issue

critical Nessus Plugin ID 61746

Language:

Synopsis

The remote host contains a runtime environment that contains methods that can aid in further attacks.

Description

The version of Oracle (formerly Sun) Java Runtime Environment (JRE) 6.x installed on the remote host is earlier than Update 35. It, therefore, potentially contains two methods that do not properly restrict access to information about other classes. Specifically, the 'getField' and 'getMethod' methods in the 'sun.awt.SunToolkit' class provided by the bundled SunToolKit can be used to obtain any field or method of a class
- even private fields and methods.

Please note this issue is not directly exploitable, rather it can aid in attacks against other, directly exploitable vulnerabilities, such as that found in CVE-2012-4681.

Solution

Update to JDK / JRE 6 Update 35 or later and remove, if necessary, any affected versions.
