Dr.Web Firewall 12.5.2.4160 on Windows incorrectly restricts applications signed by Dr.Web. A DLL for a custom payload within a legitimate binary (e.g., frwl_svc.exe) bypasses firewall filters.
Dr.Web Security Space versions 11 and 12 allow elevation of privilege for local users without administrative privileges to NT AUTHORITY\SYSTEM due to insufficient control during autoupdate.
