Hi Andreas,

Thanks for the response. We have already followed the instructions in AXIS2 
documentations to migrate to 1.7.4. We tried with a customized 
RPCServiceClient, and it picks the new HTTPClient version. However, we fear 
that the below mentioned vulnerability would still be reported as Maven 
transiently still packs the old version of HTTPClient (3.1). So we have added 
an <excludes> clause in our dependency.

This will work for now, however, it looks like a workaround-ish fix. We hope 
that AXIS2 would provide a ‘default’ fix (without having users to rely on the 
<excludes>) in a near future release (or a fork for backward compatibility?).

Eagerly awaiting your response,
Avi Sanwal

httpclient(CVE-2015-5262) - Denial of Service Vulnerability

You need to switch to the HttpClient 4.x based HTTP transport as
explained in the Axis2 1.7.0 release notes [1]. This means that you
need to create a customized axis2.xml config file, instantiate a
ConfigurationContext from that file and pass it to the
RPCServiceClient (instead of letting RPCServiceClient create a default
ConfigurationContext for you).
