Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
A Violation of Secure Design Principles issue was discovered in Schneider Electric Modicon Modbus Protocol. The Modicon Modbus protocol has a session-related weakness making it susceptible to brute-force attacks.

Fix
- Mitigation from the vendor CISA ICSA-17-101-01 · 1 productSchneider Electric has reported that they have introduced compensating controls to limit the exploitability of the identified vulnerabilities in many of the PLCs in the Modicon family; however, Schneider Electric recommends that users apply security measures to improve resiliency.
- Mitigation from the vendor CISA ICSA-17-101-01 · 1 productSchneider Electric's Momentum M1E controllers (all versions of model 171CBU98090 and all versions of model 171CBU98091) do not have built-in compensating controls to limit the exploitability of the identified vulnerabilities
- Mitigation from the vendor CISA ICSA-17-101-01 · 1 productProtect access to M1E controllers by a firewall blocking all remote/external access to Port 502.
- Mitigation from the vendor CISA ICSA-17-101-01 · 1 productEnable protection based on an authentication to connect to PLC. This method relies on a feature named Application Password. Once enabled, password-based authentication is required whenever a user connects to change their application program
- Mitigation from the vendor CISA ICSA-17-101-01 · 1 productEnable protection relying on an input (M340, Premium, Quantum) or a key switch in the front panel (Quantum) to reject remote connection or run/stop commands
- Mitigation from the vendor CISA ICSA-17-101-01 · 1 productEnable the “Access Control List protection,” where users are able to configure the restricted IP addresses that are pre-authorized to control the PLC.
