CVE-2026-16141 (GCVE-0-2026-16141)
Vulnerability from cvelistv5
Published
2026-09-15 13:57
Modified
2026-09-15 14:59
Severity ?
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE
  • CWE-798 - Use of Hard-coded Credentials
  • CWE-457 - Use of Uninitialized Variable
Summary
OpenBMC's IPMI implementation, phosphor-net-ipmid, contains a logic flaw in which an unauthenticated client can force the RAKP Message 1 handler to return before it overwrites the authentication object's constructor defaults. The IPMI service then accepts a RAKP Message 3 whose HMAC is computed with the constant 20-byte 'userKey' initialized from the string '0penBmc' and an often-predictable 'bmcRandomNum'. Several downstream vendors implement phosphor-net-ipmid as their IPMI stack, such as NVIDIA and H3C.

CVE-2026-16140 (GCVE-0-2026-16140)
Vulnerability from cvelistv5
Published
2026-09-15 13:57
Modified
2026-09-15 15:00
Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CWE
  • CWE-863 - Incorrect Authorization
Summary
OpenBMC's IPMI implementation, phosphor-net-ipmid, is vulnerable to a logic flaw where the authorization context of an existing session can be replaced with a target account while still maintaining the original integrity and encryption keys. Several downstream vendors implement phosphor-net-ipmid as their IPMI stack, such as NVIDIA and H3C. This issue effectively allows for privilege escalation without re-authentication.
