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.

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.

CWE
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
Summary
slpd-lite is a unicast SLP UDP server. Any OpenBMC system that includes the slpd-lite package is impacted. Installing this package is the default when building OpenBMC. Nefarious users can send slp packets to the BMC using UDP port 427 to cause memory overflow issues within the slpd-lite daemon on the BMC. Patches will be available in the latest openbmc/slpd-lite repository.
