ZDI-11-306 : Oracle Java IIOP Deserialization Type Confusion Remote Code
Execution Vulnerability

October 26, 2011

-- CVE ID:
CVE-2011-3521

-- CVSS:
9, AV:N/AC:L/Au:N/C:P/I:P/A:C

-- Affected Vendors:

Oracle

-- Affected Products:

Oracle Java Runtime

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Oracle Java. User interaction is required to
exploit this vulnerability in that the target must visit a malicious
page or open a malicious file.

The specific flaw exists within the way Java handles IIOP
deserialization. Due to insufficient type checking it is possible to
trick java into allowing access to otherwise protected and private
fields in built-in objects. This could be used, for example, to disable
to security manager normally in place for applets. This leads to remote
code execution under the context of the current user.

-- Vendor Response:

Oracle has issued an update to correct this vulnerability. More details
