CVE-2024-28252

Summary

CVE-2024-28252 is a vulnerability affecting CoreWCF, a .NET Core implementation of Windows Communication Foundation (WCF) services. This issue causes extra system resources to be consumed when connections are not properly closed or aborted. Two scenarios contribute to this behavior: when a client fails to initiate the NetFraming session handshake, and when a client doesn't send any requests within the ReceiveTimeout period. The bindings NetTcpBinding, NetNamedPipeBinding, and UnixDomainSocketBinding are susceptible, with NetTcpBinding being the only one capable of accepting non-local connections. Affected versions are v1.4.x and v1.5.x. The recommended solution is to upgrade to v1.4.2 or v1.5.2, as no workarounds are available.
