Summary
ASP.NET Core has incorrect default permissions that allow an authorized attacker to elevate privileges locally. The issue concerns the default permission configuration in the ASP.NET Core environment.
Risk Assessment
An attacker with valid credentials could gain higher privileges on the system, potentially leading to further escalation and host compromise.
Recommendation
Apply available ASP.NET Core updates that fix the default permissions and review permission configuration in production environments.
