Description: Apache CXF supports sending and receiving attachments via either the JAX-WS or JAX-RS specifications. It is possible to craft a message attachment header that could lead to a Denial of Service (DoS) attack on a CXF web service provider. Both JAX-WS and JAX-RS services are vulnerable to this attack. - - From Apache CXF 3.2.1 and 3.1.14, message attachment headers that are greater than 300 characters will be rejected by default. This value is configurable via the property "attachment-max-header-size". This has been fixed in revision: https://github.com/apache/cxf/commit/8bd915bfd7735c248ad660059c6b6ad26cdbcdf6 Migration: Apache CXF users should upgrade to 3.2.1 or 3.1.14 as soon as possible if they are using web services with attachments.
