CWE-269  (opens in a new tab)

How to fix?

Upgrade Steeltoe.Management.EndpointBase to version 3.4.0 or higher.

Overview

Affected versions of this package are vulnerable to Improper Privilege Management in the permission enforcement process for sensitive actuator endpoints such as heapdump, env, and threaddump. An attacker can access sensitive application data by authenticating with only restricted permissions, which are typically granted to low-trust roles such as Space Auditors.

Workaround

This vulnerability can be mitigated by explicitly setting RequiredPermissions = EndpointPermissions.Full in the options for HeapDumpEndpointOptions, EnvironmentEndpointOptions, and ThreadDumpEndpointOptions, or by registering only the required actuators individually instead of using AddAllActuators().
