CVE-2019-3980 has been observed exploited in the wild (reported by VulnCheck KEV). EIP tracks 4 public exploits from researchers including warferik, Barbarisch, CyberQuestor-infosec.

AI-analyzed exploit summary This PoC exploits CVE-2019-3980 in Dameware Remote Support to achieve remote code execution by uploading and executing a custom C# executable via a Python script that handles communication and command execution.

Description

The Solarwinds Dameware Mini Remote Client agent v12.1.0.89 supports smart card authentication which can allow a user to upload an executable to be executed on the DWRCS.exe host. An unauthenticated, remote attacker can request smart card login and upload and execute an arbitrary executable run under the Local System account.
