HIGH EXPLOITED IN THE WILD RANSOMWARE

Fujitsu M10 Firmware < 2290 - Unauthenticated Password Hash Exposure via IPMI RAKP HMAC

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2013-4786 has been observed exploited in the wild (reported by VulnCheck KEV, InTheWild.io), including in ransomware campaigns. EIP tracks 3 public exploits from researchers including Dan Farmer, fin3ss3g0d, including a Metasploit module auxiliary/scanner/ipmi/ipmi_dumphashes.

AI-analyzed exploit summary This Perl script exploits CVE-2013-4786, an information disclosure vulnerability in IPMI 2.0's RAKP protocol. It performs a brute-force attack to guess passwords by extracting HMAC hashes from the BMC's response during session establishment.

Description

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.
