Multiple security vulnerabilities have been disclosed in the Intelligent Platform Management Interface ( IPMI ) firmware for Supermicro baseboard management controllers (BMCs) that could result in privilege escalation and execution of malicious code on affected systems. The seven flaws, tracked from CVE-2023-40284 through CVE-2023-40290, vary in severity from High to Critical, according to Binarly, enabling unauthenticated actors to gain root access to the BMC system. Supermicro has  shipped  a BMC firmware update to patch the bugs. BMCs are special processors on server motherboards that support remote management, enabling administrators to monitor hardware indicators such as temperature, set fan speed, and update the UEFI system firmware. What's more, BMC chips remain operational even if the host operating system is offline, making them lucrative attack vectors to deploy  persistent malware . A brief explainer of each of the vulnerabilities is below - CVE-2023-40284, CVE-20

An analysis of firmware images across devices from Dell, HP, and Lenovo has revealed the presence of outdated versions of the  OpenSSL  cryptographic library, underscoring a supply chain risk. EFI Development Kit, aka  EDK , is an open source implementation of the Unified Extensible Firmware Interface ( UEFI ), which functions as an interface between the operating system and the firmware embedded in the device's hardware. The firmware development environment, which is in its second iteration (EDK II), comes with its own cryptographic package called  CryptoPkg  that, in turn, makes use of services from the OpenSSL project. Per firmware security company Binarly, the firmware image associated with Lenovo Thinkpad enterprise devices was found to use three different versions of OpenSSL: 0.9.8zb, 1.0.0a, and 1.0.2j, the last of which was released in 2018. What's more, one of the firmware modules named InfineonTpmUpdateDxe relied on OpenSSL version 0.9.8zb that was shipped on Au

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

A number of firmware security flaws uncovered in HP's business-oriented high-end notebooks continue to be left unpatched in some devices even months after public disclosure. Binarly, which first  revealed details  of the issues at the  Black Hat USA conference  in mid-August 2022, said the vulnerabilities "can't be detected by firmware integrity monitoring systems due to limitations of the Trusted Platform Module (TPM) measurement." Firmware flaws can have serious implications as they can be abused by an adversary to achieve long-term persistence on a device in a manner that can survive reboots and evade traditional operating system-level security protections. The high-severity weaknesses identified by Binarly affect HP EliteBook devices and concern a case of memory corruption in the System Management Mode (SMM) of the firmware, thereby enabling the execution of arbitrary code with the highest privileges - CVE-2022-23930  (CVSS score: 8.2) - Stack-based buffer
