What is CVE-2019-1372?

A remote code execution vulnerability exists in Azure App Service due to improper handling of buffer lengths during memory operations. This issue allows an attacker to execute code in the context of NT AUTHORITY\system, thereby escaping the confines of the Sandbox environment. Successful exploitation can occur when an attacker sends crafted inputs to unprivileged functions, which may not be sufficiently sanitized before execution. Microsoft has addressed this vulnerability by implementing security updates that improve input validation for user-supplied data, enhancing the overall security posture of the Azure platform.
