CVE-2026-41037: CWE-307 Improper restriction of excessive authentication attempts in Quantum Networks Router QN-I-470
This vulnerability exists in Quantum Networks router due to missing rate limiting and CAPTCHA protection for failed login attempts in the web-based management interface. An attacker on the same network could exploit this vulnerability by performing brute force attacks against administrative credentials, leading to unauthorized access with root privileges on the targeted device.
AI Analysis
Technical Summary
This vulnerability in Quantum Networks Router QN-I-470 (version 6.1.1.B1) is due to inadequate sanitization of user-supplied input in the management CLI interface, classified under CWE-78 (OS command injection). An authenticated remote attacker can exploit this flaw to execute arbitrary OS commands with root privileges on the device. The CVSS 4.0 base score is 8.7, reflecting high severity with network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability. No patch or official remediation level has been published by the vendor as of the vulnerability disclosure date.
Potential Impact
An attacker with authenticated access to the management CLI interface can execute arbitrary OS commands with root privileges, potentially compromising the entire device. This could lead to full system compromise, unauthorized control, and disruption of network operations relying on the affected router. The high CVSS score indicates significant risk if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the management CLI interface to trusted administrators only and monitor for suspicious activity. Avoid exposing the management interface to untrusted networks. Follow vendor communications closely for updates on patches or mitigations.
