You heard that right - the BMC will tell you the password hash for any valid user account you request. In short, the authentication process for IPMI 2.0 mandates that the server send a salted SHA1 or MD5 hash of the requested user’s password to the client, prior to the client authenticating. More recently, Dan Farmer identified an even bigger issue with the IPMI 2.0 specification. Here’s a little Perl program that implements it.
#Hp ilo 4 exploit cracked
The short version: the RAKP protocol in the IPMI specification allows anyone to use IPMI commands to grab a HMAC IPMI password hash that can be cracked offline. IPMI 2 uses the RAKP protocol to exchange keys, and this has a huge security risk, first identified by Dan Farmer in this post:

Currently in version 2.0, IPMI gives “out of band” access over ethernet to things like rebooting a server, measuring temperature or fan speed, or accessing an interface to a server such as IP-KVM or Serial-over-Lan. Googling for the term “Bare Metal BMC automation” leads to a lot of references about IPMI, such as this post. I previously exploited it in Zipper, but there I could log in as guest, which isn’t an option here. Zabbix is an enterprise monitoring application. zabbix/monitor/ - TCP 80Īll three of these subdomains return the same site, which is a login form for a Zabbix instance: ?
