CyberRota Analysis
AI-GeneratedIGEL OS versions prior to 12.9.0, 12.8.3 LTS, and 11.11.150 are vulnerable to a secure boot bypass that enables physically present attackers to gain unauthorized root access. By exploiting GRUB's fail-open signature verification, an attacker can place an unsigned file on the system, allowing them to boot the device's kernel with custom arguments and access a root shell. Organizations using these versions should prioritize patching to mitigate the risk of physical attacks that could compromise system integrity.

Original NVD Description
IGEL OS 12 before 12.9.0, 12.8.3 LTS and IGEL OS 11 before 11.11.150 contain a secure boot bypass vulnerability in the GRUB boot stage that allows physically present attackers to gain unauthorized root access by placing an unsigned empty file named igel.conf on a partition. Attackers can exploit GRUB's fail-open signature verification behavior to drop into an interactive GRUB prompt, then boot the device's own kernel with additional command-line arguments to obtain a root shell with the disk unlocked while leaving TPM PCR values unaltered.
