If I execute the plink command
plink user@192.168.1.12 sudo nano /etc/hosts
Upon typing the password when prompted, I am getting
sudo: no tty present and no askpass program specified
Sorry, try again.
sudo: no tty present and no askpass program specified
Sorry,try again.
sudo: no tty present and no askpass program specified

sudo: 3 incorrect password attempts
How to execute the sudo command from plink? Or is there any alternatives?

i know that the question is old but this can help
you can execute plink (putty tools)
plink -v -ssh -m "path/to/commands.txt" -l usertologin -pw PASSWORDSERVER
commands.txt:
echo -e "PASSWORD\n" | sudo -S cat /etc/passwd
sudo -S is to receive the password from stdin and with the echo -e "password\n" is to pass the password (and \n is like to press intro -new line- )
the same way you can execute the passwd command:
> echo -e "OLDPASSWORD\nNEWPASSWORD\nNEWPASSWORD" | passwd

Why are you using plink here? In general, you'd use plink to call a non-interactive script on a remote host. If you want to do interactive stuff, (like edit a file), just ssh to the server (either from your shell, using 'ssh' client on Linux, or by running putty on Windows), then edit the file.
More info on plink, and some examples, can be found here: http://the.earth.li/~sgtatham/putty/0.53b/htmldoc/Chapter7.html

Why Plink ? use SSH instead. Also SSH would need -t option for sudo commands.
From ssh man page:
-t Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote
machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty
allocation, even if ssh has no local tty.

I needed to make some folders and set perms. These blocks worked for me in PowerShell to automate. Whoever up there that is suggesting to just use SSH hopefully has figured out that is currently not the right solution. Reduction of manual process should be everyone's goal.
$null = iex "cmd /c $plinkpath -ssh -l $linuser -pw $linpass $computername `"echo $linpass | sudo -S mkdir $puppetfolder`"" *>&1
$null = iex "cmd /c $plinkpath -ssh -l $linuser -pw $linpass $computername `"echo $linpass | sudo -S chmod o+wx $puppetfolder`"" *>&1
