Issues with sqlmap, burp and SSL

[tcf]

Hi everybody,

in the process of slowly getting acquainted with Kali, I was running across a weird issue today when using sqlmap via burp on an https connection. It happened that the SSL handshake ran into an error:


# sqlmap -u https://a.b.c/test.aspx --proxy=http://localhost:8080 -v 3

sqlmap/1.0-dev - automatic SQL injection and database takeover tool

The reason for this seems to be an issue with openssl when connecting to SSLv3 systems.

I was able to fix it with a rather dirty hack and would love to hear about more decent solutions.

This is what I did:


vi /usr/share/sqlmap/lib/request/httpshandler.py

Remove ssl.PROTOCOL_SSLv23 from the _protocols list:


#_protocols = [ssl.PROTOCOL_SSLv23, ssl.PROTOCOL_SSLv3, ssl.PROTOCOL_TLSv1]
_protocols = [ssl.PROTOCOL_SSLv3, ssl.PROTOCOL_TLSv1]

Compile httpshandler.py:


python -m compileall /usr/share/sqlmap/lib/request/httpshandler.py

After this, the handshake between sqlmap and burp works like a charm.

But, I'd be very much interested in solutions that address the root cause of the issue.

Cheerz,
TC

Great workaround! thanks tcf. There is need for forcing the SSL version to get this working.

Same issue here using sqlmap 1.0-dev, burp 1.5.11, and OpenSSL 1.0.1e 11 Feb 2013. I get the following error:

[DEBUG] SSL connection error occured ('[Errno 1] _ssl.c:504: error:14077438:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert internal error')

anyone a good solution for patching python requests lib in general?

I keep getting an error when I want to use requests to post to burp https proxy:
