CVE-2024-45275Public exploitNetwork attack vector

Unauthenticated root command execution via hard-coded accounts

Published Oct 15, 2024 · Updated Oct 16, 2024

Hard-coded credentials in MB connect line mbNET.mini and Helmholz REX 100 firmware through 2.2.13 allow remote attackers to execute root commands. The HTTP server initialization script creates hidden MBCL and remote accounts, then grants them access to configuration CGI forms that execute commands, upload firmware, or change settings. No prior authentication or user interaction is required; network access to the device web service is enough for complete device compromise.
