A Java Web Start vulnerability exists in Oracle Java. The vulnerability can be exploited by remote unauthenticated attackers to execute arbitrary code on a vulnerable system.
Java Web Start enables the deployment and execution of remote applications on a local system. The instructions for application execution are specified in a Java Network Launching Protocol (JNLP) file. An input validation vulnerability exists during the processing of execution parameters. A remote attacker can exploit this vulnerability by enticing a target user to open a crafted JNLP file. In a successful attack, the attacker can execute arbitrary code within the context of the affected user.
