Apache CXF is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the services listing page. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
A flaw was found in Apache CXF prior to 3.2.1 and 3.1.14. 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.
