Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Solaris.  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in  unauthorized access to critical data or complete access to all Oracle Solaris accessible data as well as  unauthorized update, insert or delete access to some of Oracle Solaris accessible data.
