NVIDIA DGX machine learning servers vulnerabilities

NVIDIA has published fixes for vulnerabilities in NVIDIA Machine learning servers with CVSS up to 9.8.

NVIDIA DGX-1, DGX-2, and DGX A100 Servers are affected and can be hacked via BMC OOB interfaces. 




CVE‑2020‑11483 NVIDIA DGX servers contain a vulnerability in the AMI BMC firmware in which the firmware includes hard-coded credentials, which may lead to elevation of privileges or information disclosure.

CVE‑2020‑11484 NVIDIA DGX servers contain a vulnerability in the AMI BMC firmware in which an attacker with administrative privileges can obtain the hash of the BMC/IPMI user password, which may lead to information disclosure.

CVE‑2020‑11487 NVIDIA DGX servers contain a vulnerability in the AMI BMC firmware in which the use of a hard-coded RSA 1024 key with weak ciphers may lead to information disclosure.

CVE‑2020‑11485 NVIDIA DGX servers contain  a Cross-Site Request Forgery (CSRF) vulnerability in the AMI BMC firmware in which the web application does not sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request, which can lead to information disclosure or code execution.

CVE‑2020‑11486 NVIDIA DGX servers contain a vulnerability in the AMI BMC firmware in which software allows an attacker to upload or transfer files that can be automatically processed within the product's environment, which may lead to remote code execution.

CVE‑2020‑11615 NVIDIA DGX servers contain a vulnerability in the AMI BMC firmware in which it uses a hard-coded RC4 cipher key, which may lead to information disclosure.

CVE‑2020‑11488 NVIDIA DGX servers contain a vulnerability in the AMI BMC firmware in which software does not validate the RSA 1024 public key used to verify the firmware signature, which may lead to information disclosure or code execution.

CVE‑2020‑11489 NVIDIA DGX servers contain a vulnerability in the AMI BMC firmware in which default SNMP community strings are used, which may lead to information disclosure.

CVE‑2020‑11616 NVIDIA DGX servers contain a vulnerability in the AMI BMC firmware in which the Pseudo-Random Number Generator (PRNG) algorithm used in the JSOL package that implements the IPMI protocol is not cryptographically strong, which may lead to information disclosure.

Kudos: Sergey Gordeychik,  Denis Kolegov, Maria Nedyak, Roman Palkin, Anton Nikolaev.

More details: Sergey Gordeichik talks at CodeBlue and The Standoff.
