Subject [jira] [Created] (HTTPCLIENT-1803) Malformed path not handled well
Date Tue, 17 Jan 2017 22:27:26 GMT
Tyler Benson created HTTPCLIENT-1803:

             Summary: Malformed path not handled well
                 Key: HTTPCLIENT-1803
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1803
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient (async), HttpClient (classic)
    Affects Versions: 4.5.1
            Reporter: Tyler Benson

When using URIBuilder's constructor with a malformed url argument, host passed in by {{setHost}}
call not honored.

        String path = "@notexample.com/mypath"
        URI uri = new URIBuilder(path).setHost("example.com").build();
        org.junit.Assert.assertEquals("example.com", uri.getHost())

This is caused by the original string being passed into the constructor being treated as the
path, but not verifying the presence of a leading {{/}} character.
This can be seen with other arguments:

{{path = "example"}} -> {{//example.comexample}}

Fix:  URIBuilder should ensure path starts with a leading {{/}}.

Reason priority is considered Major:
In our case, this caused a security vulnerability because the user provided path was able
to override our specified host, resulting in giving network access to a sensitive environment.
 We worked around this in our code by ensuring the leading {{/}}, but this seems like something
better handled by the framework.
