[null] wireshark filter to intercept http basic-auth credentails

[Vikas Saxena]

hi guyz,

I am in middle of a war with an arrogant developer.

He has deployed a web application using apache tomcat 7.0.32 that uses htttp basic auth mecahnism over port 8080 (non-ssl)

I was asked to do a pentest for same, and this issue was easliy noticable.

Now, i need an evidence to prove my point.

I tried uding wireshark but could not catch anything using the filter http.authbasic

When i apply this filter no matching packets are displayed.

Am i using the correct filter, if not please suggest the same.

Well,

Does it have to be wireshark dump?

HTTP Basic Authentication uses base64 encoding, so get http traffic from proxy or wireshark and you can easily decode it.

So what did you look in the filter for passwords in clear text? If so then you should be reading up on http-basic auth again.

To solve your problem make a base64 encoded string of username:password and when you capture with wireshark you can use the search function to locate this encoded string. You should get that for sure.

Its http-basic and happening over http. Burp can only help you demo one part of the problem. The encoding. But he will need to capture that on network layer to prove the point.

I want to capture username and password for proxy authentication.

 

I tried filtering packets based on http.request.method="POST"  but didn't get any packets. I use a HTTP server for proxy authentication. Please help.

[Rajesh A.]

If you want to do that with wireshark 

capture packets and filter it by giving following 

http.authbasic
