A potential vulnerability was reported in the ThinkPad L390 Yoga and 10w Notebook that could allow a local attacker to escalate privileges by accessing an embedded UEFI shell.

The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad T495s, X395, T495, A485, A285, A475, A275 which may allow for unauthorized access.

An internal shell was included in BIOS image in some ThinkPad models that could allow escalation of privilege.

The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad A285, BIOS versions up to r0xuj70w; A485, BIOS versions up to r0wuj65w; T495 BIOS versions up to r12uj55w; T495s/X395, BIOS versions up to r13uj47w, while the emergency-reset button is pressed which may allow for unauthorized access.

Lenovo implemented Intel CSME Anti-rollback ARB protections on some ThinkPad models to prevent roll back of CSME Firmware in flash.

A weak default password for the serial port was reported in some Lenovo Personal Cloud Storage devices that could allow unauthorized device access to an attacker with physical access.

A vulnerability was reported in various BIOS versions of older ThinkPad systems that could allow a user with administrative privileges or physical access the ability to update the Embedded Controller with unsigned firmware.

A vulnerability was reported on some Lenovo Notebook systems that could allow an attacker with physical access to elevate privileges under certain conditions during a BIOS update performed by Lenovo Vantage.

A vulnerability was reported in ThinkPad T14s Gen 3 and X13 Gen3 that could cause the BIOS tamper detection mechanism to not trigger under specific circumstances which could allow unauthorized access.

A vulnerability was reported in ThinkPad T14s Gen 3 and X13 Gen3 that could cause the BIOS tamper detection mechanism to not trigger under specific circumstances which could allow unauthorized access.

A DLL preloading vulnerability was reported in Lenovo Driver Management prior to version 2.9.0719.1104 that could allow privilege escalation.

A vulnerability was reported in LenovoAppScenarioPluginSystem for Lenovo System Interface Foundation prior to version 1.2.184.31 that could allow unsigned DLL files to be executed.

A vulnerability in the software image verification functionality of Cisco IOS XE Software for the Cisco Catalyst 9000 Family of switches could allow an unauthenticated, physical attacker to execute unsigned code at system boot time. The vulnerability is due to an improper check in the code function that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to boot a malicious software image or execute unsigned code and bypass the image verification check part of the secure boot process of an affected device. To exploit this vulnerability, the attacker would need to have unauthenticated physical access to the device or obtain privileged access to the root shell on the device.

Possible authentication bypass due to improper order of signature verification and hashing in the signature verification call in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables

On Schneider Electric ConneXium Tofino Firewall TCSEFEA23F3F22 before 03.23, TCSEFEA23F3F20/21, and Belden Tofino Xenon Security Appliance, an arbitrary firmware image can be loaded because firmware signature verification (for a USB stick) can be bypassed. NOTE: this issue exists because of an incomplete fix of CVE-2017-11400.

A vulnerability in software image verification in Cisco IOS XE Software could allow an unauthenticated, physical attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability is due to an improper check on the area of code that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device.

A vulnerability in the software image verification functionality of Cisco IOS XE Software for Cisco Catalyst 9200 Series Switches could allow an unauthenticated, physical attacker to execute unsigned code at system boot time. This vulnerability is due to an improper check in the code function that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to boot a malicious software image or execute unsigned code and bypass the image verification check part of the boot process of the affected device. To exploit this vulnerability, the attacker needs either unauthenticated physical access to the device or privileged access to the root shell on the device. Note: In Cisco IOS XE Software releases 16.11.1 and later, root shell access is protected by the Consent Token mechanism. However, an attacker with level-15 privileges could easily downgrade the Cisco IOS XE Software running on a device to a release where root shell access is more readily available.

The tested version of Dominion Voting Systems ImageCast X does not validate application signatures to a trusted root certificate. Use of a trusted root certificate ensures software installed on a device is traceable to, or verifiable against, a cryptographic key provided by the manufacturer to detect tampering. An attacker could leverage this vulnerability to install malicious code, which could also be spread to other vulnerable ImageCast X devices via removable media.
