CVE-2018-0362 is a medium-severity vulnerability affecting Cisco 5000 Series Enterprise Network Compute System and Cisco Unified Computing E-Series Servers. It allows an unauthenticated, local attacker to bypass BIOS authentication by submitting an empty password, gaining access to a restricted set of user-level BIOS commands. The attack requires physical presence (AV:P) and has low impact on confidentiality, integrity, and availability (C:L/I:L/A:L). There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
