Date Discovered February 28, 2013
Description Oracle Java SE is prone to a remote code execution vulnerability.
An attacker can exploit this issue to execute arbitrary code in the context of the application.
This vulnerability affects the following supported versions:
JDK and JRE 7 Update 15 and prior
JDK and JRE 6 Update 41 and prior
JDK and JRE 5.0 Update 40 and prior
Block external access at the network boundary, unless external parties require service. Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity including unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Do not follow links provided by unknown or untrusted sources. Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Set web browser security to disable the execution of script code or active content. Disabling the execution of script code in the browser may limit exposure to this and other latent vulnerabilities.
Run all software as a nonprivileged user with minimal access rights.
To limit the impact of latent vulnerabilities, configure applications to run as a nonadministrative user with minimal access rights.
Updates are available. Please see the references or vendor advisory for more information.
The payloads delivered by the exploit kits are detected by Symantec as 'Trojan.Zbot' and 'Trojan.Horse'.
