CVE-2013-7397 is a medium-severity flaw (CVSS 4.3) affecting jboss fuse, async-http-client. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Async Http Client (aka AHC or async-http-client) before 1.9.0 skips X.509 certificate verification unless both a keyStore location and a trustStore location are explicitly set, which allows man-in-the-middle attackers to spoof HTTPS servers by presenting an arbitrary certificate during use of a typical AHC configuration, as demonstrated by a configuration that does not send client certificates.
