| ipmi-cipher-zero:
| VULNERABLE:
| IPMI 2.0 RAKP Cipher Zero Authentication Bypass
| State: VULNERABLE
| Risk factor: High
| Description:
|
| The issue is due to the vendor shipping their devices with the
| cipher suite '0' (aka 'cipher zero') enabled. This allows a
| remote attacker to authenticate to the IPMI interface using
| an arbitrary password. The only information required is a valid
| account, but most vendors ship with a default 'admin' account.
| This would allow an attacker to have full control over the IPMI
| functionality.
