> HttpClient permits man in the middle attacks when using HTTPS
> -------------------------------------------------------------
>
> Key: HTTPCLIENT-1256
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1256
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 3.1 Final
> Reporter: Robert Elliot
> Priority: Critical
>
> As documented here:http://www.cs.utexas.edu/~shmat/shmat_ccs12.pdf HttpClient 3.1 does not use JSSE correctly - specifically, a request over HTTPS does not validate that the returned certificate is actually for the domain originally requested. This means a man in the middle attack via DNS poisoning will work.
> I have proven this locally by setting a /etc/hosts entry for www.google.com to the IP address of github.com. When I then run the following code:
> HttpClient client = new HttpClient();
> GetMethod get = new GetMethod("https://www.google.com");
> client.executeMethod(get);
> System.out.println(get.getResponseBodyAsString());
> I am returned the contents of the github.com page. I should have had an exception warning me that the certificate was not valid for www.google.com.
> Whilst I appreciate that 3.x is not under development, given the large number of applications and libraries (such as Axis 1 & 2) that depend on version 3 it would seem responsible to fix this vulnerability.
