Arcserve published an advisory for a critical unauthenticated RCE in Arcserve UDP for Windows (public PoC published 27 June 2023). Arcserve recommends upgrading to UDP 9.1 or applying provided patches, blocking inbound UDP ports 8014/8015 where exposed, and resetting administrative credentials; Arctic Wolf noted no confirmed active exploitation but warned exploitation is likely given the public PoC.
