CVE-2026-80359: Dell Boot Optimized Server Storage (BOSS), versions prior to 2.2.13.2038, contains an On-Chip Debug and Test Interface With Improper Access

Noroxi assessment

Priority: Monitor (action score 27/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
  • Physical access to the device is required. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Dell Boot Optimized Server Storage (BOSS) 2.2.13.2038.

Low priority for now. Upgrade to Dell Boot Optimized Server Storage (BOSS) 2.2.13.2038 or later.
