CVE-2026-30081 has been officially published by MITRE.
Vulnerability Overview
| Field | Value |
|---|---|
| CVE ID | CVE-2026-30081 |
| CWE | CWE-319: Cleartext Transmission of Sensitive Information |
| Device Model | QN-I-470 |
| Firmware | 6.1.1.B1 |
| Severity | HIGH |
| Vendor | Quantum Networks |
Vulnerability Description
The administrative web interface of the affected Quantum Networks router (QN-I-470, firmware 6.1.1.B1) transmits authentication credentials in cleartext over the network.
When an administrator authenticates to the web-based management interface over HTTP, the supplied username and password are sent without any transport-layer encryption. As a result, an adjacent network attacker with access to the same broadcast domain can passively intercept network traffic and recover valid administrative credentials.
Successful credential disclosure enables complete compromise of the affected device.
Impact
An attacker capable of intercepting network traffic on the same local network can:
- Obtain valid administrative credentials
- Gain full administrative control over the affected router
- Modify critical network configuration, including routing, DNS, and firewall settings
- Perform traffic interception, redirection, or manipulation
- Establish persistent or stealthy access to the network infrastructure
Given that the affected device functions as a network gateway, successful exploitation may enable network-wide attacks against connected systems, significantly increasing the overall impact.
