Description
Oracle Java contains a vulnerability that could allow an unauthenticated, remote attacker to bypass security restrictions and execute arbitrary code on a targeted system.
The vulnerability is due to improper security restrictions imposed by the affected software. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to visit a malicious web page or follow a malicious link. Successful exploitation could allow an attacker to bypass Java sandbox security restrictions. An attacker could use this vulnerability to execute arbitrary code on the system.
Functional code that demonstrates an exploit of this vulnerability is available as a part of the Metasploit framework.
Oracle has confirmed this vulnerability and released updated software.
Warning Indicators
Oracle Java Runtime Environment (JRE) 7 Update 7 and prior are vulnerable.
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
Functional code is publicly available which may aid an attacker in exploiting this vulnerability.
An unauthenticated, remote attacker could exploit this vulnerability to bypass Java sandbox security and execute arbitrary code on a targeted system. Successful exploitation could result in a complete system comprise.
Technical Information
