Subject [jira] Commented: (AXIS2C-1465) crash in axis2_http_sender_configure_proxy_auth
Date Tue, 09 Mar 2010 14:44:27 GMT

    [ https://issues.apache.org/jira/browse/AXIS2C-1465?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12843065#action_12843065
] 

Olivier Mengué commented on AXIS2C-1465:
----------------------------------------

Here is the full HTTP response header:

HTTP/1.1 407 Proxy Authentication Required
Proxy-Authenticate: NEGOTIATE
Proxy-Authenticate: NTLM
Cache-Control: no-cache
Pragma: no-cache
Content-Type: text/html; charset=utf-8
Proxy-Connection: close
Set-Cookie: BCSI-CS-F998621D699625D2=2; Path=/
Connection: close
Content-Length: 1842

Of course I understand NTLM is not supported by Axis2/C core transport, however it should
not crash and report an error.

> My application crashes in function axis2_http_sender_configure_proxy_auth.
> Here is how the proxy is defined in axis2.xml:
>     <transportSender name="http" class="axis2_http_sender">
>         <parameter name="PROTOCOL" locked="false">HTTP/1.1</parameter>
>         <parameter name="xml-declaration" insert="false"/>
>         <!--parameter name="Transfer-Encoding">chunked</parameter-->
>         <!--parameter name="HTTP-Authentication" username="" password="" locked="true"/-->
>         <parameter name="PROXY" proxy_host="xxxxxx" proxy_port="nnnn" proxy_username=""
proxy_password=""
>  locked="false"/>
>     </transportSender>
> Here is the block where the crash occurs:
>         if(auth_type)
>         {
>             auth_type_end = axutil_strchr(auth_type, ' ');
>             *auth_type_end = AXIS2_ESC_NULL;
>             auth_type_end++;
>             /*Read the realm and the rest stuff now from auth_type_end */
>         }
> Local variables:
> force_proxy_auth=0
> auth_type="NTLM"
> So auth_type_end is NULL and writing to *auth_type_end is invalid.
> Here is the full stack trace:
