Summary
MB connect line: Sandbox escape in mbNET's LUA interpreter
Severity
High
Notes
Summary: An authenticated remote attacker can exploit an undocumented method to escape the LUA sandbox in mbNET devices, enabling the execution of arbitrary operating system commands and leading to full system compromise.
Impact: This vulnerability allows an authenticated remote attacker to fully compromise the system by executing arbitrary OS commands.
Remediation: Update mbNET/mbNET.rokey to at least version 7.3.0\ **Note**: mbNET HW1 is EOL and will not receive any further updates.
