Privilege escalation via undisclosed REST validation flaw
Published Sep 20, 2023 · Updated Sep 24, 2024
Improper input validation in the NVIDIA DGX H100 BMC REST service before 23.08.18 allows attackers to escalate privileges and read data. NVIDIA identifies the REST service as the affected locus but has not disclosed the malformed input, endpoint, or validation operation. Exploitation requires adjacent-network access and high privileges; the reported consequence is privilege escalation and information disclosure without service interruption.
