Update: Another IPMI Mishap? Researcher Claims Supermicro Devices Vulnerable

There’s more bad news for companies that rely on the Intelligent Platform Management Interface (IPMI) to manage servers and other hardware in their IT environments. Specifically: researcher Zachary Wikholm over at Cari.net has published evidence of what he says is a head-slapping vulnerability affecting devices that use IPMI Base Management Controllers (BMCs) made by the firm SuperMicro. According to Wikholm, servers equipped with Supermicro BMCs store a password file, PSBlock, in plain text and – making matters worse- leave it open to the world on port 49152. “You can quite literally download the BMC password file from any UPnP enabled Supermicro motherboard running IPMI on a public interface,” he wrote. Baseboard Management Controllers (BMCs) are small, embedded systems attached to a system’s motherboard that manage IPMI communications. Wikholm says that Supermicro has fixed the problem in the latest version of its IPMI firmware. However, companies are often reluctant to flash […]

UEFI: Security, BIOS and the Internet of Things

One of the notable trends in recent years has been the drive, among malicious actors, to compromise devices in new- and hard-to-detect ways. An area of interest and exploration is malicious software that can attack a computer’s BIOS – the small bit of code that runs when a computing device is first powered on. BIOS malware is so powerful because it offers adversaries the possibility of getting a foothold on systems prior to an operating system and the security features- and applications that run there. Successful BIOS attacks give attackers almost total control over the system they are installed on. BIOS malware isn’t a new idea. In fact, it has been around since the late 1990s, when the Chernobyl Virus was identified. That virus could wipe a machine’s BIOS, a well as the contents of its hard drive. But BIOS threats have been getting more attention lately. Proof of concept malware appeared as recently […]

IPMI’s Inconvenient Truth: A Conversation With Dan Farmer

The work of brilliant computer security researchers often borders on a kind of madness. After all, it takes dedication and a certain amount of monomania to dig through the mush of disassembled source code or the output of application fuzzers and find the one software vulnerabilities – or chain of vulnerabilities – that might lead to a successful attack. Often, this work puts you at odds with what most of us consider “the real world.” Notably: the well-respected researcher Dragos Ruiu had many in the security community wondering about his sanity after he sounded the alarm about a super stealthy piece of BIOS malware he dubbed “BadBIOS” that seemed to be everywhere and nowhere, all at once. Dan Farmer finds himself in a similar position as he continues to sound alarms about the security threat posed by insecure implementations of the Intelligent Platform Management Interface (IPMI)– a ubiquitous protocol used to do remote […]

IPMI Insecurity Affects 200k Systems

It has been almost a year since security researcher Dan Farmer first warned of the danger posed by Intelligent Platform Management Interface (IPMI) – a ubiquitous protocol used to do remote management of servers. According to a new report, however, that warning went unheeded. Writing last week (PDF), Farmer said that a world-wide scan for systems using the Intelligent Platform Management Interface (IPMI) protocol identified over 230,000 Baseboard Management Controllers (BMCs) exposed to the Internet. As many as 90% of the exposed systems could be compromised by exploiting what Farmer characterized as “basic configuration and protocol weaknesses.” Even more worrying, the 230,000 systems that are Internet accessible are probably just a fraction of all the vulnerable systems that might be attacked, with many deployed on (hackable) corporate and private networks. Farmer is reiterating calls for public and private sector organizations to wake up to the dangers posed by IPMI. Hackers who are able to compromise Baseboard Management […]

Cisco Combines Linux, IOS For Internet of Things

Networking equipment giant Cisco Systems said that it is combining elements of the open source Linux operating system to its IOS firmware, launching a new architecture it calls “IOx” that will connect the billions of intelligent devices that will make up the Internet of Things. The new architecture was announced at Distributech in San Antonio – a trade show for the utility industry, on Wednesday. The company said IOx will make it easier for its customers to connect Internet of Things devices to back-end resources and the larger Internet.  As it stands, the Internet of Things ecosystem is fragmented. Intelligent devices like the Nest Thermostat typically communicate back to proprietary cloud resources and might communicate with their surroundings using any one of a number of wireless protocols, including Bluetooth, Bluetooth Low Energy, Zigbee, Z-Wave, and so on.  That balkanization has made it hard to create IoT solutions that span different families […]
