REDHAT-BUG-880443
First published: Tue Nov 27 2012(Updated: )
Tibor Jager, Kenneth G. Paterson and Juraj Somorovsky have described XML encryption backwards compatibility attacks against various frameworks, including Apache CXF. An attacker can use these flaws to force a server to utilize insecure, legacy cryptosystems when secure cryptosystems are enabled on endpoints. This could expose flaws in the underlying legacy cryptosystems, such as <a href="https://access.redhat.com/security/cve/CVE-2011-1096">CVE-2011-1096</a> and <a href="https://access.redhat.com/security/cve/CVE-2011-2487">CVE-2011-2487</a>. This flaw also affects the jbossws-native stack.
