ICS Advisories

Risk evaluation

The affected devices have security vulnerabilities that can be used to bypass authentication. Code can be executed on the devices through command injection and local file inclusion. Path traversal and modified schemata can be used to read sensitive information such as password hashes or private keys from the devices.

Mitigation summary

Install update 1.7.8.

Risk evaluation

Critical vulnerabilities have been discovered in the product due to outdated software components.The impact of the vulnerabilities on the affected device may result in Denial of service Bypassing of authentication Information disclosure

Mitigation summary

External protective measures are required: Disable the webserver after configuration, if possible, by following these steps: - Enable SSH via the web server. - Login to the SSH server. - Disable the webserver via SSH portal. - Reboot the device. or: - Use HTTPS rather than HTTP while using the webserver. - Minimize network exposure for affected products and ensure that they are not accessible via the Internet. - Isolate affected products from the corporate network. - If remote access is required, use secure methods such as virtual private networks(VPNs). Pepperl+Fuchs will provide an update to address some of these vulnerabilities in the future.

Risk evaluation

Risk evaluation

A stored cross-site scripting vulnerability has been discovered in the profinet gateway LB8122A.1.EL. An attacker can write an HTML tag with up to 32 characters in the message field of a HART transmitter. The HTML tag is interpreted as HTML when the HART information is displayed in a webbrowser. If the HTML tag contains a link to a manipulated page, a user can be tricked into accessing this page. Furthermore, an attacker can access information about running processes via the SNMP protocol. Sending such SNMP read commands can also trigger a reboot.

Mitigation summary

Please install the updated firmware V1.3.13.

Risk evaluation

Critical vulnerabilities have been discovered in the utilized Bluetooth component. For more information see: https://kb.cert.org/vuls/id/799380

The device will play a confirmation sound when a Bluetooth connection is successfully established and a status LED labeled BT indicates that a Bluetooth connection is active. This can be used to detect an unauthenticated connection.

Risk evaluation

PACTware passwords are stored in a recoverable format (CVE-2020-9403) PACTware passwords may be modified without knowing the current password (CVE-2020-9404)

Mitigation summary

Any further changes in 'user role'-administration will need a confirmation by using the current login password. This will be fixed in following versions (and higher): PACTware 5.0.5.31 PACTware 4.1 SP6 Overview about version history: https://pactware.com/de/service You can protect yourself against manipulation by restricting the access to the PC where PACTware is installed. In case of not known passwords it can be reset by reinstallation of PACTware (all PACTware versions).
