CVE-2022-34302 – New Horizon Datasys Inc.We have identified vulnerabilities in three different bootloaders, which have been assigned the following CVEs: This section summarizes the key points of each vulnerability, however, a more in-depth analysis is available in our recent DEF CON talk ( link). Failing to do so will result in the device failing to boot. HOWEVER, it is important to note that any devices that use the three affected bootloaders will need to obtain new bootloaders from the affected vendors BEFORE updating the DBX. Ultimately, organizations will need to update the DBX database on their devices, which maintains a list of disallowed code. Since this issue impacts multiple parts of the supply chain, the mitigation process may require multiple steps. Such an update would require the attacker to have administrator privileges, however, such escalations are common and readily available. As a result, an attacker could simply install the vulnerable bootloader, and it would be trusted by the target device. By default, this CA is trusted by virtually all traditional Windows and Linux-based systems such as laptops, desktops, servers, tablets, and all-in-one systems. Much like our previous GRUB2 BootHole research, these new vulnerable bootloaders are signed by the Microsoft UEFI Third Party Certificate Authority. These vulnerabilities could be used by an attacker to easily evade Secure Boot protections and compromise the integrity of the boot process enabling the attacker to modify the operating system as it loads, install backdoors, and disable operating system security controls. Note: Peace Shield items cannot be activated while your troops are reinforcing a Government Building.As part of our continuing research into vulnerable and malicious bootloaders, we have identified three new bootloader vulnerabilities which affect the vast majority of devices released over the past 10 years including x86-64 and ARM-based devices.During all stages, if a player's city is successfully attacked in the center area of the map, that city will be automatically teleported to a random place outside the center area. ![]() ![]() The Alliance who possesses the Codes at the end of this stage wins the "DEFCON One" event. The goal of this stage is to protect the Nuclear Launch Codes from being stolen. If an attack is successful, the Codes will automatically be transported to the attacker's HQ. Until the end of the Defend stage, all other Alliances can attack the HQ in an attempt to steal the Nuclear Launch Codes. This item will be automatically transported to the Alliance HQ of the winning Alliance.
