A critical remote code execution vulnerability exists in CSLA .NET framework versions 5.5.4 and below due to insecure deserialization when using WcfProxy with the obsolete NetDataContractSerializer. This vulnerability allows unauthenticated remote attackers to execute arbitrary code on affected systems without user interaction, potentially leading to complete system compromise. While no active exploitation has been reported in CISA KEV and no public POC is mentioned, the vulnerability's network-exposed nature and low attack complexity make it a high-priority security concern.
