Denial Of Service (DoS)

jbossws-common is vulnerable to denial of service (DoS). The vulnerability exists as it was found that JBoss Web Services Native did not properly protect against recursive entity resolution when processing Document Type Definitions (DTD). A remote attacker could exploit this flaw by sending a specially-crafted HTTP POST request to a deployed web service, causing excessive CPU and memory consumption on the system hosting that service. If the attack is repeated to consume all available network sockets, the server will become unavailable. This flaw did not affect systems using JBoss Web Services CXF.
