CVE-2026-2417
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 Pharos Controls Mosaic Show Controller firmware version 2.15.3 could allow an unauthenticated attacker to bypass authentication and execute arbitrary commands with root privileges.
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 confidenceA critical authentication bypass vulnerability in Pharos Controls Mosaic Show Controller firmware 2.15.3 allows unauthenticated attackers to execute arbitrary commands with root privileges by directly accessing a critical function that lacks authentication checks.

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 the installed productLocate the Pharos Controls Mosaic Show Controller device or verify the product name in your asset inventory. Confirm the device model matches the Mosaic Show Controller product line.Affected if The device is not a Pharos Controls Mosaic Show Controller
-
Check the firmware versionAccess the device's web management interface or use the vendor's diagnostic tool to retrieve the current firmware version. Look for the version number displayed in the system info or about section.Affected if The installed firmware version is 2.15.3
-
Verify network exposure of management interfaceDetermine if the device's web-based management interface (typically ports 80/443 or vendor-specific ports) is accessible from untrusted networks. Use network scans or review firewall rules to identify exposed management endpoints.Affected if The management interface is exposed to untrusted networks or the internet without network segmentation
-
Test for unauthenticated access to critical functionsIf you have authorized access, attempt to reach the critical function endpoint referenced in the CVE (e.g., a command execution or administrative function) without providing credentials. Observe if the request succeeds without authentication redirects or failures.Affected if The critical function can be accessed without any authentication credentials and returns expected responses or executes commands
You are affected if you have a Pharos Controls Mosaic Show Controller running firmware version 2.15.3 with its management interface accessible to network segments where untrusted users could reach the vulnerable unauthenticated function.
Generated from the published advisory. Verify against your own configuration.
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 firmware patch if available; otherwise implement network segmentation to isolate the device and deploy compensating controls such as firewall rules restricting access to management interfaces.
