VAR-201112-0254
Vulnerability from variot - Updated: 2023-12-18 12:38The modbus_125_handler function in the Schneider Electric Quantum Ethernet Module on the NOE 771 device (aka the Quantum 140NOE771* module) allows remote attackers to install arbitrary firmware updates via a MODBUS 125 function code to TCP port 502. Modbus is a communication protocol that defines the message structure that the controller can recognize and use. ----------------------------------------------------------------------

DESCRIPTION: Ruben Santamarta has reported some security issues in multiple Schneider Electric modules, which can be exploited by malicious people to bypass certain security restrictions.
1) The Telnet service contains undocumented hardcoded credentials, which can be exploited to gain access to the service and e.g.
2) The Windriver Debug service contains undocumented hardcoded credentials, which can be exploited to gain access to the service and e.g.
3) The FTP service contains undocumented hardcoded credentials, which can be exploited to gain access to the service and e.g. modify HTTP passwords and upload malicious firmware.
Please see the ICS-CERT's advisory for a list of affected products and versions.
SOLUTION: Restrict access to trusted hosts only.
