OpenSSL

After scanning a website with 'Nessus'.

I found out that the website is, to quote

 
  
 The remote host is using a version of OpenSSL which is
older than 0.9.6m or 0.9.7d

There are several bug in this version of OpenSSL which may allow
an attacker to cause a denial of service against the remote host.

Nessus solely relied on the banner of the remote host
to issue this warning


Solution: Upgrade to version 0.9.6m (0.9.7d) or newer

Risk Factor : High
CVE : CVE-2004-0079, CVE-2004-0081, CVE-2004-0112
BID : 9899
Other references : IAVA:2004-B-0006, OSVDB:4316, OSVDB:4317, OSVDB:4318
Plugin ID : 12110

 
 
 
 The remote host is using a version of OpenSSL which is
older than 0.9.6j or 0.9.7b

This version is vulnerable to a timing based attack which may
allow an attacker to guess the content of fixed data blocks and
may eventually be able to guess the value of the private RSA key
of the server.

An attacker may use this implementation flaw to sniff the
data going to this host and decrypt some parts of it, as well
as impersonate your server and perform man in the middle attacks.

Is there anyway I can exploit this, or are there any articles I can read to help me.

Report this log to the admin, i think mozzer or aldarhawk wrote a good article that help you reporting bugs to the admin.

If you want, install this version of openssl locally and try exploits locally. This is a good method of work in hacking and in security.

Okay thanks,

But reporting it to the admin wasn't really what I had in mind ;)

I shall try finding exploits locally as you suggested :D
