Remote denial of service in ASP.NET Core enables unauthenticated network attackers to exhaust server resources and disrupt application availability. The CVSS 7.5 score reflects high availability impact with low attack complexity and no required privileges or user interaction, though no public exploit identified at time of analysis. Microsoft (secure@microsoft.com) is the reporting source via MSRC, indicating a vendor-coordinated disclosure.
Uncontrolled resource allocation in ASP.NET Core enables unauthenticated remote attackers to exhaust system resources and cause denial of service without requiring user interaction. The vulnerability affects .NET applications exposed to network access, allowing attackers to trigger unbounded resource consumption from any network location. A patch is available to address this issue.
Denial of service against HTTP/2 server implementations allows remote unauthenticated attackers to exhaust server resources by rapidly opening and immediately canceling (RST_STREAM) large numbers of streams over a single connection, a technique dubbed the 'Rapid Reset' attack. The flaw is confirmed actively exploited (CISA KEV) following large-scale weaponization observed August through October 2023, with publicly available exploit code and an EPSS score of 94.45% placing it in the 100th percentile for likelihood of exploitation. Virtually every major HTTP/2 stack - including nghttp2, Netty, Envoy, and Eclipse Jetty - is affected.
