# IPsec VPN input validation flaw lets privileged remote attacker run root commands

Improper input validation in the IPsec VPN function can let a remote attacker with high privileges inject system commands. Those commands run with root privileges on the affected device.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

unknown: no vendor advisory found yet. Check your VPN router/gateway vendor's security advisories (CERT@VDE if an industrial device) for CVE-2026-105982, and whether IPsec VPN is enabled and the management interface reachable by privileged accounts.

## Timeline

- 2026-11-03T09:19:50+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-105982
- 2026-11-03T09:21:06+00:00 analyst — Searched NVD, CERT@VDE advisory list, general web: vendor/product not identifiable yet. CVSS was assigned by info@cert.vde.com (CERT@VDE CNA), so the vendor is likely an industrial/OT vendor with a VDE advisory, but no VDE advisory naming this CVE is indexed (list shows none). Do not guess the product; revisit once the CERT@VDE advisory appears. Similar InHand/Cudy/Teltonika IPsec CVEs found are different IDs, not this one.

## From the sources

Improper input validation in the IPsec VPN function may allow a remote attacker with high privileges to inject system commands and execute them with root privileges.
