('binary' encoding is not supported, stored as-is) A repost, my previous one seem to have failed. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ____________________________________________________________________________ SECURITY vulnerability in ECS-K7S5A(L) boards ____________________________________________________________________________ DESCRIPTION =========== The administrator-password set in the BIOS of the K7S5A(L) locks out BIOS-access from the console. However, it does not disable access to the boot-menu. Eventhough the system is configured to boot from harddrive only, and has an admin-password set, someone with physical access to the system can still boot from floppy or CD using the boot-menu. IMPACT ====== Security: Moderate Any person with physical access to the machine can reboot from a removable medium (introduced by him-self). By doing this, authentication mechanisms on the machine can be bypassed, composmising the data on the system and the system itself. Working from this compromised system with e.g. root/admin access can threaten the rest of a network, depending on the architecture and authentication mechanisms. AFFECTED VERSIONS ================= All K7S5AL-boards, confirmed up to BIOS V.02/02/06 WORKARROUNDS ============ None at this moment, restrict physical access to the console where possible. FIXES ===== None at this moment.
