You might try Foundstone's SSLDigger (free) to help verify. It's provides a
detail report of actual ciphers used. IMHO: Nessus only identifies surface
blemishes with web apps.

Subject: verify HTTPS 'vulnerabilities'

List,

Simple question:

I have a report from Nessus telling me that a web server is offering 'export
class' cyphers for it's SSL/TLS service. Nessus also managed to obtain an
internal IP address from the host (which is correct).
Only HTTPS is open.

However the target host requires basic authentication, and I don't have any
credentials to obtain access. I would like to verify these manually, and
would usually just use something like wfetch. However, I'm not getting the
usual prompt that my encryption is too weak.
Instead in the response I can see a message saying the page cannot be
displayed. There is also no sign of the internal IP address.

Can anyone tell me how they would prove that they are not false positives (I
know the IP address is correct, but the client may want to replicate the
vulnerability so they can be sure when they go to fix it)?

thanks

Dan
