An elevation of privilege vulnerability exists when the .NET Framework common language runtime (CLR) allows file creation in arbitrary locations. An attacker who successfully exploited this vulnerability could write files to folders that require higher privileges than what the attacker already has. To exploit the vulnerability, an attacker would need to log into a system. The attacker could then specify the targeted folder and trigger an affected process to run. The update addresses the vulnerability correcting how the .NET Framework CLR process logs data.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
