Summary
Report One MyReport Updater through 2.1.1 exposes an unauthenticated gRPC service on TCP port 9095 that allows remote attackers to redirect the SYSTEM updater by invoking the UpdateConfigReferent method. Attackers can point the updater to a malicious reference server serving modified module archives with matching MD5 digests to write files and execute code as SYSTEM.
