[Contribution] Add TrendMicro Azure ML vulnerabilities

[korniko98]

Summary (give a brief description of the issue)

We investigated Azure ML, a managed MLaaS from Microsoft. Our findings talk of two broad classes of security issues, namely:
Insecure logging of sensitive information: We found five instances of credentials leaking in cleartext on Compute Instances due to insecure usage of open-source components and insecure system design of how the environment was being provisioned.
Sensitive information disclosure: We found a case of exposed APIs in cloud middleware leaking sensitive information from Compute Instances. Network-adjacent attackers could leverage the vulnerability after initial access to laterally move or snoop in on the commands executed using a Jupyter terminal on a Compute Instance.
