CVE-2025-9963
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 path traversal vulnerability in Novakon P series allows to expose the root file system "/" and modify all files with root permissions. This way the system can also be compromized.This issue affects P series: P – V2001.A.C518o2 until P-2.0.05 Build 2026.02.06 (commit d0f97fd9).
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 path traversal vulnerability in Novakon P series network devices allows attackers to use directory traversal sequences (e.g., ../) to escape the web root and access the entire root filesystem / with root privileges. This enables both unauthorized read access to sensitive system files and modification of any file on the device with highest permissions.

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 device modelLog into the device admin interface or check the device label/display for the exact model name (look for 'Novakon P series' or similar branding)Affected if The device is a Novakon P series device
-
Determine firmware versionNavigate to the device's system settings, about page, or check the firmware version via CLI command 'ver' or similar - compare against the fixed version P-2.0.05 Build 2026.02.06Affected if Firmware version is lower than P-2.0.05 Build 2026.02.06 or cannot be determined
-
Confirm web interface is accessibleAttempt to access the device's web management interface via HTTP/HTTPS on the device's IP address (typically ports 80 or 443)Affected if The web management interface is exposed and reachable on the network
-
Test for path traversal vulnerabilityIf you have authorized access, send a crafted HTTP request to the web interface using a path traversal pattern such as 'GET /../../../../etc/passwd' or similar endpoint - observe if the response returns file contents from outside the web rootAffected if The device returns file contents from the root filesystem ('/') when using '../' sequences in requests
You are affected if you have a Novakon P series device running firmware versions earlier than P-2.0.05 Build 2026.02.06 with an accessible web management interface.

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 the vendor firmware patch (P-2.0.05 Build 2026.02.06 or later). If unavailable, restrict network access to the device and monitor for anomalous HTTP requests containing path traversal patterns.
