A flaw in the BMC RAKP+ implementation may allow an attacker to send a request followed by a specially crafted RAKP message and establish an RMCP+ session, which could then be used to execute commands.
The BMC does not correctly enforce integrity and encryption requirements for IPMI commands. An attacker may be able to craft packets that execute arbitrary commands on an active session.

An OS command injection vulnerability exists because of insufficient input filtering. An attacker can inject a command payload into a BMC function; the payload may execute when the related service is restarted.
TL;DR: We identified 36,872 internet-exposed BMCs, and 24,650 of them disclosed password-derived authentication hashes before login because of CVE-2013-4786. More than 30% of the returned hashes were linked to passwords that could be recovered using common wordlists or predictable factory password formats. The exposure affected modern Supermicro and HPE servers, including systems operated by GPU providers. The bigger risk is that a compromised BMC gives an attacker highly privileged access below the operating system. Because BMC management networks are often poorly segmented and lightly monitored, one exposed interface can become a foothold into broader data center infrastructure. We also created an interactive map where you can explore the exposed systems: https://lavahq.io/bmcradar
There is a vulnerability in the Supermicro BMC web function at Supermicro MBD-X13SEDW-F. After logging into the BMC Web server, an attacker can use a specially crafted payload to trigger the Stack buffer overflow vulnerability.
Supermicro BMC Insyde SMASH shell program has a stacked-based overflow vulnerability
The Supermicro BMC implementation allows remote attackers to bypass authentication and execute arbitrary IPMI commands by using cipher suite 0 (aka cipher zero) and an arbitrary password.
