Code execution via KVM input validation failure
Published Sep 20, 2023 · Updated Sep 24, 2024
Improper input validation in NVIDIA DGX H100 BMC before 23.08.07 allows remote authenticated users to execute code through the KVM service. The KVM service accepts attacker-controlled input without adequate validation, but NVIDIA has not disclosed the affected request, parser, or operation. Exploitation requires low-privilege access from an adjacent network and can also disclose information, elevate privileges, or interrupt the BMC.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <23.08.07
- Affected versionversion=All versions prior to 23.08.07
