DeepSurface Security Advisory: Local Privilege Escalation in Erlang on Windows (CVE-2021-29221)
Erlang is a popular general-purpose programming language and runtime environment, with support for concurrency commonly found on many distributed systems. When distributed on Windows machines, the Erlang emulator can also be run as a service with the erlsrv.exe command. This seems to be commonly used with popular software, such as CouchDB.
