Permissions, Privileges, and Access Controls
Java Web Start in Sun JDK and JRE 5.0 Update 12 and earlier, and SDK and JRE 1.4.2_15 and earlier, on Windows does not properly enforce access restrictions for untrusted applications, which allows user-assisted remote attackers to read local files via an untrusted application.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
