The following cyber advisory was issued by the New York State Office of Information Technology Services and is intended for State government entities. The information may or may not be applicable to the general public and, accordingly, the State does not warrant its use for any specific purposes.

ITS ADVISORY NUMBER:
2013-033

DATE(S) ISSUED:
03/15/2013

SUBJECT:
Vulnerabilities in Oracle Java SE Could Allow Remote Code Execution

OVERVIEW:

Vulnerabilities have been discovered in Oracle Java SE that can lead to remote code execution. The Java Platform, Standard Edition (SE) is used to develop and deploy Java applications on desktops and servers. These vulnerabilities may be exploited if a user visits, or is redirected to a specifically crafted web page. Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the Java application. Depending on the privileges associated with the application, an attacker could execute arbitrary code in the context of the application, and bypass security restrictions.

SYSTEMS AFFECTED:

  • Oracle Java 7 Update 17. Earlier versions may also be affected.

RISK:
Government:

  • Large and medium government entities: High
  • Small government entities: High

Businesses:

  • Large and medium business entities: High
  • Small business entities: High

Home users: High

DESCRIPTION:
Vulnerabilities have been discovered in Oracle Java SE that can lead to remote code execution. In order to exploit these vulnerabilities, an attacker must first create a web page with a specially crafted applet designed to leverage this issue. When the web page is visited, the attacker-supplied code is run in the context of the affected application. Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the java application. Depending on the privileges associated with the application, an attacker could execute arbitrary code in the context of the application, and bypass security restrictions.

These vulnerabilities were demonstrated at a recent cyber security forum; however no public working exploits are reported to be available.

RECOMMENDATIONS:
We recommend the following actions be taken:

  • Once the patches become available and after appropriate testing, apply the patches from Oracle immediately.
  • Set web browser security to disable the execution of script code or active content.
  • Run all software as a non-privileged user (one without administrative privilege.es) to diminish the effects of a successful attack.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
