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

Supermicro (SMC) SMASH services contain an Arbitrary code execution issue in X14DBG-DAP and X14DBI. An authorized attacker can exploit SMASH’s input capability to compromise data integrity or launch a Denial-of-Service (DoS) attack against the BMC.
There is a vulnerability in the Supermicro BMC SMTP service at Supermicro AS-2115HS-TNR. An attacker may obtain administrator privileges and inject specially crafted characters into the SMTP service configuration. This may cause the underlying system to execute unintended commands during process invocation.
Potential impact includes denial-of-service attacks, arbitrary code execution, or permanent compromise of the controller.
The web interface in the Intelligent Platform Management Interface (IPMI) baseboard management controller (BMC) implementation on Supermicro X11 and M11 based devices, with firmware versions before 3.17.02, allows remote authenticated users to execute arbitrary commands via a crafted request targeting vulnerable cgi endpoints.
The configuration functionality in the Intelligent Platform Management Interface (IPMI) baseboard management controller (BMC) implementation on Supermicro X11 and M11 based devices, with firmware versions through 3.17.02, allows remote authenticated users to execute arbitrary commands.
A web server in the Intelligent Platform Management Interface (IPMI) baseboard management controller (BMC) implementation on Supermicro X11 and M11 based devices, with firmware versions up to 3.17.02, allows remote unauthenticated users to perform directory traversal, potentially disclosing sensitive information.
Supermicro X11SSL-CF HW Rev 1.01, BMC firmware v1.63 was discovered to contain insecure permissions.
