Please see the below table for the affected firmware versions. Please visit the advisories for the latest updates. HP released advisories on Aug 9 and updated them on Aug 11 and Sep 7. There are multiple firmware versions and devices affected by these SMM vulnerabilities, such as laptops, desktops, point-of-sale systems, and edge computing nodes. HP Firmware Affected by These Vulnerabilities: Exploiting this issue could lead to escalating privileges to SMM. This is an SMM memory corruption vulnerability in an HP device allowing a possible attacker to write fixed or predictable data to SMRAM. Exploiting this issue could lead to escalating privileges to SMM.ĬVSS v3.1: AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:HĪ SMM callout on HP device, which allows a attacker to access the System Management Mode and execute arbitrary code.ĬVSS v3.1:AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H This a an SMM memory corruption vulnerability in an HP device allowing a possible attacker to write fixed or predictable data to SMRAM. Check out the page for more technical details. These vulnerabilities in HP BIOS let attackers, not just Implant persistent malware programs that survive operating system updates and re-installations but are also capable of bypassing UEFI Secure Boot, Intel Boot Guard, virtualization-based security, and endpoint security systems. Summary Of these Six Unpatched SMM Vulnerabilities in HP Enterprise Devices: How To Fix these Six Unpatched SMM Vulnerabilities in HP Enterprise Devices?.HP Firmware Affected by These Vulnerabilities:.Summary Of these Six Unpatched SMM Vulnerabilities in HP Enterprise Devices:.Since these vulnerabilities affect multiple HP products, including laptops, desktops, point-of-sale systems, and edge computing nodes, let’s see how to fix these six unpatched SMM vulnerabilities in HO Enterprise devices in this post. Owners of HP devices should be aware of these six unpatched SMM vulnerabilities in HO Enterprise devices. ![]() Since these attacks occur at the firmware level, it’s been said that these types of attacks can easily evade OS-level security systems and survive reboots.Īll these SMM vulnerabilities are considered high in severity since they have got a score from 7.5 to 8.2 out of 10 in the CVSS scoring system. Attackers can abuse these vulnerabilities to implant malicious codes that enable attackers to maintain long-time persistence. According to the research team, these vulnerabilities can pose a severe threat to vulnerable devices if exploited. The Binarly security research team has published a report about six unpatched SMM vulnerabilities in HP Enterprise devices.
