What is CVE-2020-5807?

An unauthenticated remote attacker can exploit a vulnerability in FactoryTalk Diagnostics by sending specially crafted data to RsvcHost.exe, which is listening on TCP port 5241. This exploitation allows the attacker to manipulate entries in the FactoryTalk Diagnostics event log. When a local user accesses this log via the FactoryTalk Diagnostics Viewer (FTDiagViewer.exe), it can cause an unhandled exception due to excessively long fields in the log entry, potentially leading to unexpected behavior or crashes in the application.
