Vulnerability from csaf_lenzese - Published: 2022-07-11 10:00 - Updated: 2022-07-11 10:00

Summary

Lenze: Vulnerability in the OPC-UA authentification connection in the firmware

Notes

Summary: The machine controller of the cabinet series include an OPC-UA server which uses an user management to authenticate clients via anonymous or user/password authentication. If the user/password authentication is selected, password verification is skipped upon second login. As a result, cases occur in which users can establish communication without correct authentication. This vulnerability is not located in the OPC-UA protocol or server, but in the interface to the products firmware. This Security Advisory is only relevant for the following use cases: • the user management has been activated on the machine controller (is deactivated by default) • the OPC-UA Server is used • Data are transferred via a symbol configuration (is not available by default)

Impact: The exploitation of the missing critical step in authentication may result in unauthorized use of the OPC-UA interface.

Mitigation: As part of a security strategy, Lenze SE recommends the following general defense measures to reduce the risk of exploits: • Only use the products in a protected and controlled environment to minimize network impact and to ensure that they are inaccessible from outside. • Use external firewalls to protect the automation system network and to separate it from other networks. Remark: One Measure should be to block port 4840 via the external firewall and open this port for authenticated access only. • Use Virtual Private Networks (VPN) tunnels when remote access is required. • Use IDS (Intrusion Detection Systems) where possible to detect anomalies in the network. • Activate and use user administration and password functions. • Use encrypted communication links. • Restrict access to both the development tools and their projects and the products of the automation system by physical means, operating system functions, etc. • Protect the development tool by using the latest virus detection solutions. • Use of certificate-based communication via the message security modes Sign or Sign&Encrypt and trust of the corresponding client certificates on the machine controller by the OPC-UA server. This can reduce the risk of exploiting this vulnerability.

Remediation: Install version V01.08.01.3021, which solves the identified security vulnerability.

CVE-2022-2302

Multiple Lenze products of the cabinet series skip the password verification upon second login. After a user has been logged on to the device once, a remote attacker can get full access without knowledge of the password.

CWE-287 - Improper Authentication

Mitigation As part of a security strategy, Lenze SE recommends the following general defense measures to reduce the risk of exploits: • Only use the products in a protected and controlled environment to minimize network impact and to ensure that they are inaccessible from outside. • Use external firewalls to protect the automation system network and to separate it from other networks. Remark: One Measure should be to block port 4840 via the external firewall and open this port for authenticated access only. • Use Virtual Private Networks (VPN) tunnels when remote access is required. • Use IDS (Intrusion Detection Systems) where possible to detect anomalies in the network. • Activate and use user administration and password functions. • Use encrypted communication links. • Restrict access to both the development tools and their projects and the products of the automation system by physical means, operating system functions, etc. • Protect the development tool by using the latest virus detection solutions. • Use of certificate-based communication via the message security modes Sign or Sign&Encrypt and trust of the corresponding client certificates on the machine controller by the OPC-UA server. This can reduce the risk of exploiting this vulnerability.

Vendor Fix Install version V01.08.01.3021, which solves the identified security vulnerability.
