  • XML External Entities Blowup
    This attack takes advantage of the entity replacement property of XML where the value of the replacement is a URI. A well-crafted XML document could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
