Sun Java Runtime Environment (JRE) Applet Class Loader unauthorized access

sun-java-class-unauthorized-access (35491) The risk level is classified as MediumMedium Risk

Description:

Sun Java Runtime Environment (JRE) could allow a remote attacker to gain unauthorized access to the system, caused by a vulnerability in the Applet Class Loader. By persuading a victim to load a specially-crafted Java applet, a remote attacker could establish a socket connection to a local host and gain unauthorized access to the system. An attacker could exploit this vulnerability to possibly launch further attacks on the vulnerable system.
