Title
OpenBMC IPMI Privilege Escalation via Retargeted RAKP 1
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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
