Azure App Service Remote Debugging Enabled

Description¶

This weakness arises when the Azure App Service has remote debugging enabled in a production environment. Remote debugging opens a debug port that allows direct runtime access to the application process, enabling attackers to inspect memory, execute arbitrary code, extract secrets from memory, and gain complete control over the application. This feature is intended for development purposes only, and creates a critical security vulnerability when enabled in production.

Impact¶

Remote debugging provides direct access to the application's runtime environment, including: memory dumps containing secrets and credentials, ability to execute arbitrary code within the application context, access to environment variables and configuration, inspection of live request/response data, and potential escalation to the underlying infrastructure. This combination enables complete application compromise and data exfiltration.
