Unauthenticated remote code execution via default passwords
Published Jul 24, 2024 · Updated Oct 21, 2025
Use of default passwords in affected Acronis Cyber Infrastructure builds allows remote attackers to execute commands over the network. Acronis has not identified the account, service, or command-execution path that accepts the unchanged credentials. No prior authentication or user action is required; successful access grants command execution on the infrastructure platform.
