CVE-2026-41037: Qntmnet Qn-I-470 Firmware Security Vulnerability (CVSS 8.7)

This vulnerability exists in Quantum Networks router due to improper access control and insecure default configuration in the web-based management interface. An unauthenticated attacker could exploit this vulnerability by accessing exposed API endpoints on the targeted device. Successful exploitation of this vulnerability could allow the attacker to access sensitive information, including internal endpoints, scripts and directories on the targeted device.

This vulnerability exists in Quantum Networks router due to lack of enforcement of strong password policies in the web-based management interface. An attacker on the same network could exploit this vulnerability by performing password guessing or brute-force attacks against user accounts, leading to unauthorized access to the targeted device.

This vulnerability exists in Quantum Networks router due to inadequate sanitization of user-supplied input in the management CLI interface. An authenticated remote attacker could exploit this vulnerability by injecting arbitrary OS commands on the targeted device. Successful exploitation of this vulnerability could allow the attacker to perform remote code execution with root privileges on the targeted device.

Databasus 3.7.0 through 3.61.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to brute-force password reset codes via POST /api/v1/users/reset-password. Attackers can request a six-digit code for a known email, then guess it without rate limiting, lockout, or invalidation to take over accounts, including administrators.

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) do not enforce rate limiting or account lockout mechanisms on authentication endpoints. This allows attackers to perform unrestricted brute-force attempts against administrative credentials.

Netherman Portal del Hermano (portaldelhermano.es) before 2026-10-06 contains a broken authentication vulnerability in its password-recovery flow at the POST /password/create-access and POST /password/email endpoints, allowing unauthenticated attackers to take over any member account across all tenants by exploiting the lack of rate limiting and distinct error messages that act as oracles for each of the four identity-verification factors (DNI, date of birth, phone number, last four IBAN digits). Attackers can confirm the DNI via the oracle, brute-force the date of birth and IBAN digits, obtain the phone number through open-source intelligence, then submit an attacker-controlled email field so the password reset link is delivered to them, enabling full account takeover including profile data, full IBAN, and fiscal documents.
