CVE-2022-36642
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 local file disclosure vulnerability in /appConfig/userDB.json of Telos Alliance Omnia MPX Node through 1.0.0-1.4.9 allows attackers to access users credentials which makes him able to gain initial access to the control panel with high privilege because the cleartext storage of sensitive information which can be unlatched by exploiting the LFD vulnerability.
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 analysisThe application checks who you are but not whether you're allowed to perform a given action, so any authenticated user can reach things meant for others. This is the classic “change the ID in the URL” bug. The fix is an authorization check on every request, evaluated against the acting user's permissions.

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 · scoped1.5.0
Omnia MPX Node Firmware version 1.5.0 or later
- Check the current firmware version on the Omnia MPX Node device via the admin interface or CLI
- Download the Omnia MPX Node firmware version 1.5.0 or later from the official Telos Alliance support website
- Back up the current device configuration before performing the firmware upgrade
- Upload the firmware file through the device's web-based admin panel or via TFTP/FTP depending on available options
- Wait for the firmware upload and installation to complete - do not power off the device during this process
- After reboot, verify the new firmware version is installed (1.5.0 or later)
- Verify the /appConfig/userDB.json endpoint no longer returns sensitive credentials without authentication
- Change all user passwords in the control panel since they may have been compromised
