ASP.NET Core Elevation of Privilege Vulnerability
An elevation of privilege vulnerability exists when a Kestrel web application fails to validate web requests.
An attacker who successfully exploited this vulnerability could perform HTML injection attacks.
To exploit the vulnerability, an attacker could send a specially crafted request, containing injected HTML, to the web application. The specially crafted request would initiate a "password reset" email to the target user. Depending on the target user email client, the injected HTML could trigger as soon as the target user opens the "password reset" e-mail.
The security update addresses the vulnerability by correcting how a Kestrel web application validates web requests.
