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.

The tested version of Dominion Voting Systems ImageCast X’s on-screen application hash display feature, audit log export, and application export functionality rely on self-attestation mechanisms. An attacker could leverage this vulnerability to disguise malicious applications on a device.

The tested version of Dominion Voting Systems ImageCast X has a Terminal Emulator application which could be leveraged by an attacker to gain elevated privileges on a device and/or install malicious code.

The tested version of Dominion Voting Systems ImageCast X allows for rebooting into Android Safe Mode, which allows an attacker to directly access the operating system. An attacker could leverage this vulnerability to escalate privileges on a device and/or install malicious code.

The tested version of Dominion Voting System ImageCast X can be manipulated to cause arbitrary code execution by specially crafted election definition files. An attacker could leverage this vulnerability to spread malicious code to ImageCast X devices from the EMS.

Applications on the tested version of Dominion Voting Systems ImageCast X can execute code with elevated privileges by exploiting a system level service. An attacker could leverage this vulnerability to escalate privileges on a device and/or install malicious code.

The authentication mechanism used by technicians on the tested version of Dominion Voting Systems ImageCast X is susceptible to forgery. An attacker with physical access may use this to gain administrative privileges on a device and install malicious code or perform arbitrary administrative actions.

The authentication mechanism used by poll workers to administer voting using the tested version of Dominion Voting Systems ImageCast X can expose cryptographic secrets used to protect election information. An attacker could leverage this vulnerability to gain access to sensitive information and perform privileged actions, potentially affecting other election equipment.

The authentication mechanism used by voters to activate a voting session on the tested version of Dominion Voting Systems ImageCast X is susceptible to forgery. An attacker could leverage this vulnerability to print an arbitrary number of ballots without authorization.

A flawed pseudorandom number generator in Dominion Voting Systems ImageCast Precinct (ICP and ICP2) and ImageCast Evolution (ICE) scanners allows anyone to determine the order in which ballots were cast from public ballot-level data, allowing deanonymization of voted ballots, in several types of scenarios. This issue was observed for use of the following versions of Democracy Suite: 5.2, 5.4-NM, 5.5, 5.5-A, 5.5-B, 5.5-C, 5.5-D, 5.7-A, 5.10, 5.10A, 5.15. NOTE: the Democracy Suite 5.17 EAC Certificate of Conformance mentions "Improved pseudo random number algorithm," which may be relevant.
