ENDRESS+HAUSER: Ecograph T utilizing Webserver firmware version 1.x has improper privilege management

Published Nov 19, 2020 CVSS 3.1 · 9.1 Critical EPSS < 1% KEV · Not listed
Description
Endress+Hauser Ecograph T (Neutral/Private Label) (RSG35, ORSG35) with Firmware version prior to V2.0.0 is prone to improper privilege management. The affected device has a web-based user interface with a role-based access system. Users with different roles have different write and read privileges. The access system is based on dynamic "tokens". The vulnerability is that user sessions are not closed correctly and a user with fewer rights is assigned the higher rights when he logs on.

Remediation

Vendor Solution

Endress+Hauser will not change this behavior. Customers are recommended to take the measures for Temporary Fix / Mitigation as described above.


Vendor Workaround

Customers should configure a perimeter firewall to block traffic from untrusted networks and users to the device. These recommendations will be incorporated into the device documentation (operating instructions). Change default password for operator, service and admin account.
