New BMC Supply Chain Vulnerabilities Affect Servers from Dozens of Manufacturers

You are here: Home / General Cyber Security News / New BMC Supply Chain Vulnerabilities Affect Servers from Dozens of Manufacturers
December 5, 2022

A few diverse security flaws have been disclosed in American Megatrends (AMI) MegaRAC Baseboard Management Controller (BMC) application that could direct to remote code execution on vulnerable servers.

“The affect of exploiting these vulnerabilities include distant command of compromised servers, remote deployment of malware, ransomware and firmware implants, and server bodily problems (bricking),” firmware and hardware security business Eclypsium said in a report shared with The Hacker Information.

BMCs are privileged independent techniques inside servers that are applied to management minimal-amount components configurations and control the host running technique, even in situations when the device is powered off.

Collectively referred to as BMC&C, the freshly identified issues can be exploited by attackers owning obtain to distant administration interfaces (IPMI) this kind of as Redfish, most likely enabling adversaries to attain command of the systems and put cloud infrastructures at risk.

The most severe among the issues is CVE-2022-40259 (CVSS score: 9.9), a scenario of arbitrary code execution by means of the Redfish API that involves the attacker to by now have a least level of entry on the system (Callback privileges or greater).

CVE-2022-40242 (CVSS rating: 8.3) relates to a hash for a sysadmin consumer that can be cracked and abused to get administrative shell access, though CVE-2022-2827 (CVSS score: 7.5) is a bug in the password reset aspect that can be exploited to establish if an account with a distinct username exists.

“[CVE-2022-2827] allows for pinpointing pre-current end users and does not direct into a shell but would give an attacker a listing of targets for brute-drive or credential stuffing attacks,” the scientists described.

The results when again underscore the relevance of securing the firmware offer chain and ensuring that BMC systems are not specifically uncovered to the internet.

“As info centers are inclined to standardize on particular hardware platforms, any BMC-degree vulnerability would most very likely use to big quantities of gadgets and could perhaps influence an full details heart and the products and services that it delivers,” the firm said.

The conclusions arrive as Binarly disclosed several superior-effects vulnerabilities in AMI-dependent products that could final result in memory corruption and arbitrary code execution in the course of early boot phases (i.e., a pre-EFI ecosystem).

Before this May, Eclypsium also uncovered what is actually termed a “Pantsdown” BMC flaw impacting Quanta Cloud Technology (QCT) servers, a thriving exploitation of which could grant attackers whole command more than the products.
