VULNERABILITY SUMMARY

Eclypsium researchers have discovered a vulnerability — dubbed “BootHole” — in the GRUB2 bootloader configuration file utilized by most Linux systems that can be used to gain arbitrary code execution during the boot process, even when Secure Boot is enabled. Attackers exploiting this vulnerability can install persistent and stealthy bootkits or malicious bootloaders that could give them near-total control over the victim device.

This configuration file is an external file commonly located in the EFI System Partition and can therefore be modified by an attacker with administrator privileges without altering the integrity of the signed vendor shim and GRUB2 boot loader executables. This could allow an authenticated, local attacker to modify the contents of the GRUB2 configuration file to ensure that the attacker’s chosen code is run before the operating system is loaded.

The vulnerability affects systems using Secure Boot, even if they are not using GRUB2. Almost all signed versions of GRUB2 are vulnerable, meaning virtually every Linux distribution is affected. In addition, GRUB2 supports other operating systems, kernels and hypervisors. The problem also extends to any Windows device that uses Secure Boot with the standard Microsoft Third Party UEFI Certificate Authority. Thus the majority of laptops, desktops, servers and workstations are affected.

Canon Medical is investigating this broad reaching vulnerability to define the scope of products affected and to determine a list of vendors providing relevant updates.

The Department of Homeland Security and CISA ICS-CERT issued a critical security advisory warning covering multiple newly discovered vulnerabilities affecting Internet-connected devices manufactured by multiple vendors.

VULNERABILITY SUMMARY

A networking stack is a software component that provides network connectivity over the standard internet protocols. In this specific case these protocols include ARP, IP (versions 4 and 6), ICMPv4, UDP and TCP communications protocols. The Treck networking stack is used across a broad range of industries (medical, government, academia, utilities, etc.), from a broad range of device manufacturers – a fact which enhances their impact and scope, as each manufacturer needs to push an update for their devices independently of all others.

The impact of these vulnerabilities will vary due to the combination of build and runtime options used while developing different embedded systems. This diversity of implementations and the lack of supply chain visibility has exasperated the problem of accurately assessing the impact of these vulnerabilities. In summary, a remote, unauthenticated attacker may be able to use specially-crafted network packets to cause a denial of service, disclose information, or execute arbitrary code.

NOTE: This is a hardware-centric suite of vulnerabilities. The “Ripple20” is not specific to Canon Medical software.

NOTE: Canon Medical has discovered that related vendor patching for this attack vector has extended beyond the 19 vulnerabilities identified in the original “Ripple 20” announcement by JSOF (see below).

Microsoft has released a security advisory (ADV200001) that currently only includes workarounds and mitigations that can be applied in order to safeguard vulnerable systems from attacks. At the time of writing, there is no patch yet available for this issue. Microsoft said it is working on a fix, to be released at a later date.

While Microsoft said it was aware that the IE zero-day was being exploited in the wild, the company described these as “limited targeted attacks,” suggesting the zero-day was not broadly exploited, but rather that it was part of attacks aimed at a small number of users. These limited IE zero-day attacks are believed to be part of a larger hacking campaign, which also involves attacks against Firefox users.

VULNERABILITY SUMMARY

A remote code execution (RCE) vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website, for example, by sending an email.

REFERENCES

This IE RCE zero-day is also tracked as CVE-2020-0674

RESOLUTION

While this vulnerability and its current Microsoft-provided workaround is not anticipated to directly affect Canon Medical Products, deployments of said products include the affected Internet Explorer file(s) listed in the advisory. Corporations should follow their company policies when considering the configuration mitigations provided in the Microsoft Advisory ADV200001 linked above.

DICOM.org has reported the following Security Advisory:

VULNERABILITY SUMMARY

The DICOM Standards Organization has reported a data validation vulnerability in the preamble defined by the DICOM File format. According to this report, the vulnerability is exploitable by embedding executable code into the 128-byte preamble. A malicious actor could modify a DICOM file preamble so that it is treated as both an executable program and as a DICOM file. A user might be somehow convinced to execute the file.

Note:

The DICOM Network Communications protocol between modalities, PACS, and display systems does not transmit a preamble and is not subject to this vulnerability.

RESOLUTION

Review link provided above for details and vulnerability scenarios.

For Canon Medical customers, always exercise caution by reviewing or AV (Antivirus)  scanning the contents of any portable media (CDs, USBs, etc.) to determine that all files are legitimate DICOM files. Canon Medical recommends that affected users reach out to their specific AV vendor to determine if their solution properly scans for the affected file type. In the situation where an AV solution cannot be installed, affected users should take steps to make sure that they have processes and procedures in place to scan portable/removable media for suspicious files before introducing the media into their medical networks.
