CVE-2023-28312Public exploit

Information disclosure via unauthenticated DSIMountAgent endpoints

Published Apr 11, 2023 · Updated Jan 23, 2025

Information disclosure in Microsoft Azure Machine Learning before 3.0.02199.0001 allows remote attackers to read compute-instance service logs. The DSIMountAgent service listens on TCP port 46802 by default and exposes its HTTP service and log endpoints without authentication. Reachability requires control of a virtual machine in the same subnet as the compute instance; disclosed Jupyter logs can contain commands, secrets, tokens, or credentials.
