CWE-200Published: November 19, 2020· Updated: Jun 17, 2026

6.5

CVSS v3.1

Official Description

Endress+Hauser Ecograph T (Neutral/Private Label) (RSG35, ORSG35) and Memograph M (Neutral/Private Label) (RSG45, ORSG45) with Firmware version V2.0.0 and above is prone to exposure of sensitive information to an unauthorized actor. The firmware release has a dynamic token for each request submitted to the server, which makes repeating requests and analysis complex enough. Nevertheless, it's possible and during the analysis it was discovered that it also has an issue with the access-control matrix on the server-side. It was found that a user with low rights can get information from endpoints that should not be available to this user.

Technical Analysis

CVE-2020-12496 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 6.5.

From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
