CVE-2019-6834
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA CWE-502: Deserialization of Untrusted Data vulnerability exists which could allow an attacker to execute arbitrary code on the targeted system with SYSTEM privileges when placing a malicious user to be authenticated for this vulnerability to be successfully exploited. Affected Product: Schneider Electric Software Update (SESU) SUT Service component (V2.1.1 to V2.3.0)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceDeserialization vulnerability (CWE-502) in Schneider Electric Software Update (SESU) SUT Service component versions 2.1.1 through 2.3.0 allows authenticated attackers to execute arbitrary code with SYSTEM privileges. The attacker must first have valid user authentication to exploit this flaw.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm SESU installationCheck for Schneider Electric Software Update installation on the system using system information tools (such as Programs and Features on Windows, or package management tools on Linux)Affected if SESU is installed and the version is between 2.1.1 and 2.3.0 inclusive
-
Identify SESU versionLocate the installed version of Schneider Electric Software Update, typically found in the application properties, registry, or by querying the installed software metadataAffected if The installed version matches 2.1.1, 2.2.x, or 2.3.0
-
Verify SUT Service statusCheck whether the SUT Service component is installed and running as a service on the systemAffected if The SUT Service is present and running, enabling the vulnerable deserialization endpoint
-
Assess authentication exposureReview access controls and authentication mechanisms for the SESU service to determine if unauthorized users could obtain valid credentialsAffected if The service is accessible to users who could obtain or use valid authentication credentials
A system is affected if Schneider Electric Software Update version 2.1.1 through 2.3.0 is installed with the SUT Service component running and accessible to authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate SESU SUT Service to a patched version beyond V2.3.0 and review authentication mechanisms to ensure only authorized users can access the vulnerable service component.
