🚨 Supermicro server BMCs: a CVSS 9.8 flaw may let an attacker inject IPMI commands into an active session 🆔 CVE-2026-18450 · CVSS 3.1 9.8 (Supermicro, CNA): the BMC doesn't correctly enforce integrity and encryption requirements for IPMI commands, so crafted packets may execute arbitrary commands on an active RMCP+ session 📦 Part of an 8-CVE BMC firmware advisory (Oct 26, 2026) credited to runZero researchers, incl. CVE-2026-65219 · 7.4: an out-of-order RAKP message 3 may grant an IPMI session ✅ Fixed BMC firmware is listed per motherboard across X11-X14 and H11-H14 boards (e.g. X12SPi-TF: 01.07.27); a few SKUs are still TBD ⚠️ Supermicro says it is not aware of malicious use in the wild. Not in CISA KEV 🛡️ Update the BMC firmware and keep IPMI/BMC interfaces off the internet 🔗 https://www.supermicro.com/en/support/security_BMC_IPMI_Oct_2026_1 #Supermicro #IPMI #CVE
