Vulnerability details

Weak authentication in ASP.NET Core & Visual Studio allows an unauthorized attacker to elevate privileges over a network.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

CVE-2025-24070 enables remote exploitation of weak authentication in ASP.NET Core applications (public-facing web apps) to impersonate users and elevate privileges via RefreshSignInAsync, directly facilitating T1190 (Exploit Public-Facing Application) and T1068 (Exploitation for Privilege Escalation).
