By adding files to an existing installation's directory, a local attacker could hijack accounts of other users running Erlang programs or possibly coerce a service running with "erlsrv.exe" to execute arbitrary code as Local System. This can occur only under specific conditions on Windows with unsafe filesystem permissions. ### POC #### Reference No PoCs from references. #### Github - https://github.com/go-bi/go-bi-soft
