Hello and thanks for posting. I checked the iDRAC settings on this server and I had the community string changed in both places. Nessus is showing this vulnerability for port 8161. If I check resource monitor, core.service.exe is what is using this port. This appears to be AppAssure. Any ideas on where to change this string in AppAssure?
