Hi.
I managed to pwn all hosts but I miss ws02, I feel stuck I can’t find a way to get into.I tried all credential that I collected on each service and I did not find CVEs or similar, any help?
I missed this flags:
Update the policy!
Single or double quotesUpdate the policy makes me think that I should exploit some information that I should already have but I have not success
I missed these flags as well - I would be very happy if somebody could point out where these flags are hidden (via PM). 
Thank you.
