AI-analyzed exploit summary This exploit leverages a vulnerability in the Sun Java Virtual Machine to bypass the Java Security Model, allowing arbitrary code execution. It attempts to load a restricted class to confirm vulnerability.

Description

The loadClass method of the sun.applet.AppletClassLoader class in the Java Virtual Machine (JVM) in Sun SDK and JRE 1.4.1_03 and earlier allows remote attackers to bypass sandbox restrictions and execute arbitrary code via a loaded class name that contains "/" (slash) instead of "." (dot) characters, which bypasses a call to the Security Manager's checkPackageAccess method.
