Pardon in advance if this is a very noob question..
So I am learning to use nmap command and currently, I am doing a scan to check for the OS details of an image.
The command I have used is nmap -O -sV <ip address> and I am slightly confused by the OS details it outputted as I am trying to derive the exact OS version, to check if there are any vulnerability in the version.
It is as follows:
Running: Linux 3.X|4.X
OS CPE: cpe:/o:linux:linux_kernel:3 cpe:/o:linux:linux_kernel:4
OS details: Linux 3.2 - 4.9
While I am unable to access/ log into the said image, based off the above result, can I presume that there are 2 different Linux OS versions, in this case, one is running on Linux 3.2 and the other is on Linux 4.9?
Is it possible that an image can have multiple OS (as seen above, assuming what I mentioned above is correct)?
Many thanks in advance.
