services / Azure / Web App slot app setting

App settings of an Azure App Service deployment slot, injected into the running app as environment variables.

App settings routinely hold API keys, passwords, and connection secrets returned in cleartext; treated as credential material.

Creating/updating a slot app setting alters a runtime environment variable the app consumes, letting an attacker redirect dependencies or inject config the app's identity acts upon.

Risks

1. Data manipulation (HIGH)
2. Lateral movement (BOOST)

Scope: CRITICAL

This privilege may grant access to sensitive data from a significant fraction of organizational functions, allow interruption of critical organizational services, or its exploit could lead to significant privilege escalation.
