Password-hash disclosure via unauthenticated bootloader arguments
Published Jun 13, 2024 · Updated Aug 2, 2024
Authentication bypass in Vigilant Fixed LPR Coms Box firmware 3.1.171.9 and earlier allows physically proximate attackers to read password hashes. The GRUB bootloader accepts custom arguments that bypass authentication and expose the appliance file system. Exploitation requires physical access to the device; the documented consequence is file-system access and password-hash disclosure.
