Permission Target Name | What the Permission Allows | Risks of Allowing this Permission |
---|---|---|
setDefaultAuthenticator | The ability to set the way authentication information is retrieved when a proxy or HTTP server asks for authentication | Malicious code can set an authenticator that monitors and steals user authentication input as it retrieves the input from the user. |
requestPasswordAuthentication | The ability to ask the authenticator registered with the system for a password | Malicious code may steal this password. |
specifyStreamHandler | The ability to specify a stream handler when constructing a URL | Malicious code may create a URL with resources that it would normally not have access to (like file:/foo/fum/), specifying a stream handler that gets the actual bytes from someplace it does have access to. Thus it might be able to trick the system into creating a ProtectionDomain/CodeSource for a class even though that class really didn't come from that location. |
