CVE-2017-12624

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.

MEDIUM 5.5EPSS 3.70%

Does this matter?

Lower severity and a low EPSS score (3.70%). Track it; it rarely justifies an emergency change on its own.

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".
