CVE-2023-31170
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 · uneditedAn Inclusion of Functionality from Untrusted Control Sphere vulnerability in the Schweitzer Engineering Laboratories SEL-5030 acSELerator QuickSet Software could allow an attacker to embed instructions that could be executed by an authorized device operator. See Instruction Manual Appendix A and Appendix E dated 20230615 for more details. This issue affects SEL-5030 acSELerator QuickSet Software: through 7.1.3.0.
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 confidenceThe SEL-5030 acSELerator QuickSet Software contains a vulnerability where an attacker can embed malicious instructions within files or data that get processed when an authorized operator uses the software. This allows execution of attacker-controlled functionality through the trusted operator's session, likely via insecure deserialization, script injection, or unsafe file/include processing.

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.
-
Determine installed QuickSet versionOpen the QuickSet application and navigate to Help > About, or check Programs and Features in Windows Control Panel for the installed version of SEL-5030 acSELerator QuickSetAffected if The installed version is 7.1.3.0 or any earlier version (any version <= 7.1.3.0)
-
Identify project file sourcesReview recent QuickSet project files (.qsp, .sel, .xml or other project/config files) that have been opened. Check the default project directory and recent files list within the applicationAffected if Any project files from untrusted or unknown sources have been opened in the software
-
Inspect application data directoriesCheck user-accessible directories where QuickSet stores project files, configurations, and exports (typically under Documents or AppData folders) for unexpected or suspicious files with unusual extensionsAffected if Unexpected files with potentially malicious content are present in QuickSet data directories
-
Review deserialization and file processing behaviorMonitor or inspect the QuickSet application logs and any configurable settings related to file deserialization, script execution, or external file inclusion (check application preferences or configuration files if accessible)Affected if File deserialization, script execution, or external file inclusion features are enabled or used without verification
You are affected if the installed QuickSet version is 7.1.3.0 or earlier AND any untrusted or suspicious project files have been opened in the software.

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 dataApply vendor patches when available; avoid opening untrusted QuickSet project files, configurations, or attachments from unverified sources; implement network segmentation and least-privilege access for operators managing SEL devices.
