CVE-2023-34392
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 Missing Authentication for Critical Function vulnerability in the Schweitzer Engineering Laboratories SEL-5037 SEL Grid Configurator could allow an attacker to run arbitrary commands on managed devices by an authorized device operator. See Instruction Manual Appendix A and Appendix E dated 20230615 for more details. This issue affects SEL-5037 SEL Grid Configurator: before 4.5.0.20.
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 confidenceMissing authentication vulnerability in SEL-5037 SEL Grid Configurator allows an attacker to execute arbitrary commands on managed devices. The vulnerability affects the critical function of command execution without proper authentication checks, potentially allowing unauthorized command injection into grid/utility management devices.

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.
-
Identify installed version of SEL-5037 SEL Grid ConfiguratorLocate and retrieve the currently installed version of the SEL-5037 SEL Grid Configurator software on the systemAffected if version is less than 4.5.0.20
-
Compare version to affected rangeCompare your installed version against the affected version range of versions prior to 4.5.0.20Affected if installed version falls below 4.5.0.20
-
Confirm the command execution interface is presentVerify that the SEL Grid Configurator software with command execution capabilities is installed and operationalAffected if the software is installed and version is below 4.5.0.20
The environment is affected if SEL-5037 SEL Grid Configurator version is below 4.5.0.20, as this version range contains the missing authentication vulnerability for command execution.

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.
dbcve · scoped4.5.0.20
Upgrade SEL-5037 SEL Grid Configurator to version 4.5.0.20 or later to patch the missing authentication vulnerability.
SEL-5037 SEL Grid Configurator version 4.5.0.20
- Obtain SEL Grid Configurator version 4.5.0.20 or later from the official SEL download portal at selinc.com
- Ensure all managed devices are backed up and in a known good state before proceeding with the upgrade
- Stop any running instances of SEL Grid Configurator
- Install version 4.5.0.20 following the standard SEL software installation procedures
- After installation, verify the installed version matches 4.5.0.20 or later
- Test that the vulnerability is remediated by confirming authentication is now required for critical functions
