The Chassis Management Board in Entrust nShield Connect XC, nShield 5c, and nShield HSMi through 13.6.11, or 13.7 (patched in 13.6.12 (LTS) and 13.9.0 (STS)), allows a physically proximate attacker to persistently modify firmware and influence the (insecurely configured) appliance boot process. To exploit this, the attacker must modify the firmware via JTAG or perform an upgrade to the chassis management board firmware. This is called F03.

CVE-2024-36345—1.2%
——0Improper input validation in the AMD OverDrive (AOD) System Management Mode (SMM) module could allow a privileged attacker to perform an out-of-bounds read, potentially resulting in loss of confidentiality.6dCVE-2025-653966.1 MED11.7%
——4A vulnerability in the boot process of Blurams Flare Camera version 24.1114.151.929 and earlier allows a physically proximate attacker to hijack the boot mechanism and gain a bootloader shell via the UART interface. This is achieved by inducing a read error from the SPI flash memory during the boot, by shorting a data pin of the IC to ground. An attacker can then dump the entire firmware, leading to the disclosure of sensitive information including cryptographic keys and user configurations.120d
