Key Vulnerability Information from Screenshot Vulnerability Title BeeTel 777VR1 Broadband Router Web Management Interface Uses Hardcoded Default Credentials and Allows Unlimited Brute-Force Authentication Attempts Affected Product Product: BeeTel 777VR1 Broadband Router Firmware Versions: V01.00.09 / V01.00.09_55 Component: Web Management Console Vulnerability Classification CWE-521 - Weak Password Requirements CWE-98 - Use of Hard-coded Credentials CWE-307 - Improper Restriction of Excessive Authentication Attempts OWASP A2 - Broken Authentication Vulnerability Description The router's web-based management console uses default credentials (admin / password) and does not enforce a mandatory password change upon first login. The interface does not implement rate limiting, account lockout, or attempt throttling, making it susceptible to brute-force and credential-stuffing attacks. Successful exploitation allows full admin control over the router, network configuration modifications, and the ability to use the router as a pivot point for further attacks. Impact Successful exploitation results in administrative control over the router, network configuration modifications, and vulnerability to further attacks. Severity Critical Attack Vector Network-based Network access to the web management interface required No specific privileges required No interaction with the user required Reproduction Steps Connect to the router's web management interface Enter default credentials during authentication Observe that authentication succeeds without requiring a password change Simulate brute-force attacks and lack of rate limiting Replication Process Screenshots Included Security Recommendations Remove static default credentials Enforce mandatory password change on first login Implement rate limiting, authentication delays, or account lockout mechanisms Restrict management interface exposure to trusted networks only Video Demonstration of Exploits Links provided for in-depth reproduction steps Additional Notes Reference for documentation on method used
