Abstract

The ACL model is unable to make correct access decisions for interactions involving more than two principals, since required information is not retained across message sends. Though this deficiency has long been documented in the published literature, it is not widely understood. This logic error in the ACL model is exploited by both the clickjacking and Cross-Site Request Forgery attacks that affect many Web applications.
