CyberRota Analysis
AI-GeneratedCoreWCF versions prior to 1.8.1 and 1.9.1 on Windows are vulnerable due to inadequate validation of the ds:Reference DigestMethod in the WS-Security 1.0 receive pipeline, potentially allowing the use of insecure digest algorithms like SHA-1. This could lead to acceptance of tampered messages, undermining the integrity of communications. Organizations using affected versions should prioritize upgrading to the fixed versions to mitigate this low-severity risk.

Original NVD Description
CoreWCF is a port of the service side of Windows Communication Foundation (WCF) to .NET Core. Prior to 1.8.1 and 1.9.1, the CoreWCF WS-Security 1.0 receive pipeline validates ds:SignedInfo SignatureMethod against the configured SecurityAlgorithmSuite but does not validate each ds:Reference DigestMethod, allowing a sender to use a rejected digest algorithm such as SHA-1 while the message is still accepted. This issue is fixed in versions 1.8.1 and 1.9.1.
