SSL Not Working
Opened this issue · 1 comments
When scanning a host that runs Apache 2.4.18 on both 80 (for http) and 443 (for https), the scheme doesn't appear to change to https, causing the ssl enum scans to fail. My initial guess was that the service was being misidentified by the nmap scan, but I've attached the nmap scan (with some info omitted) as well and it appears to label the service correctly as 'ssl/http'.
My other guess is that perhaps once 'http' is chosen as the scheme when it first scans port 80, it doesn't do a second check for scheme when it's scanning port 443? Looking at the timing for when the output files were created, it definitely look like port 80 is scanned before port 443. Not sure, just throwing it out there. Please let me know if I can provide any additional info.

Nikto appears to work fine, but I believe it will automatically try https if http fails. I noticed you had a note in the code about # -C all potentially slowing it down?
Perhaps the nikto_ssl variable is not changing to ' -ssl' for the same reason the scheme is having issues and this is causing nikto to test with http first before https (causing the slow speeds)?
'443_http_nmap.txt' doesn't require scheme, so no issues there.
Is this still being maintained?
