## Overview

The IPMI 2.0 specification supports RMCP+ Authenticated Key-Exchange Protocol (RAKP) authentication, which allows remote attackers to obtain password hashes and conduct offline password guessing attacks by obtaining the HMAC from a RAKP message 2 response from a BMC.

## Affected

- `fujitsu_m10_firmware <= 2290`
- `intelligent_platform_management_interface = 2.0`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
