Summary
Endress+Hauser: Multiple products are vulnerable to code injection
Notes
Summary: Echo Curve Viewer is an utility used for offline visualization of previously recorded envelope curve data. Envelope curve records are exported from other Endress+Hauser software products like FieldCare as .curves files. Echo Curve Viewer opens .curves files and displays their contents. The .curves files contain device- specific C# calculation scripts as .cs files, that are needed for the interpretation of certain curve record types. Echo Curve Viewer loads .curves files and executes the contained C# code.
Impact: .curves files are not authenticated and universally trusted by the Echo Curve Viewer. Therefore, the contained C# code is executed without further authentication or validation. Potential attack vector: manipulated .cs files with malicious C# code may be included in .curves file.
Remediation: - For standalone Echo Curve Viewer installations, download and install Echo Curve Viewer version >=6.00.00 from the Endress+Hauser Software Portal - For bundled installations with FieldCare SFE500, download and install FieldCare SFE500 Package version >= 1.40.1 from the Endress+Hauser Software Portal external link - For Field Xpert Devices, the required update is installed automatically during startup. This requires a working internet connection and (under certain circumstances) a valid maintenance period and/or a connection to the E+H Netilion Cloud. Please refer to the Field Xpert documentation for details regarding the update mechanism.
CVE-2024-6596

An unauthenticated remote attacker can run malicious c# code included in curve files and execute commands in the users context.

9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Vendor Fix - For standalone Echo Curve Viewer installations, download and install Echo Curve Viewer version >=6.00.00 from the Endress+Hauser Software Portal - For bundled installations with FieldCare SFE500, download and install FieldCare SFE500 Package version >= 1.40.1 from the Endress+Hauser Software Portal external link - For Field Xpert Devices, the required update is installed automatically during startup. This requires a working internet connection and (under certain circumstances) a valid maintenance period and/or a connection to the E+H Netilion Cloud. Please refer to the Field Xpert documentation for details regarding the update mechanism.
