Authorization Bypass in TOTOLINK LR350 /formLoginAuth.htm

IdentifiersCVE-2024-10654CWE-287

CVE-2024-10654 is a critical authorization bypass vulnerability in TOTOLINK LR350 routers up to firmware version 9.3.5u.6369. The vulnerability exists in the /formLoginAuth.htm endpoint, where improper validation of the 'authCode' parameter allows remote attackers to bypass authentication by supplying a crafted value (e.g., '1'). This enables unauthorized access to protected resources or administrative functions on the device.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Remote attackers can bypass authentication controls, potentially gaining administrative access to the router. This could allow full compromise of the device, including configuration changes, network traffic interception, or further attacks on internal network resources.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, restrict remote access to the device's management interface using network-level controls (e.g., firewall rules, VPN). Disable WAN-side management and monitor for unauthorized access attempts until the device can be patched.

Remediation

Patch, then assume compromise.

Upgrade the TOTOLINK LR350 firmware to version 9.3.5u.6698_B20230810 or later, which addresses the improper authorization check in /formLoginAuth.htm.

IoT_vulnMaturityPoCVerified exploit

This repository documents proof-of-concept (PoC) exploits for authentication bypass vulnerabilities in TOTOLINK LR350 and T6 routers. The vulnerabilities (CVE-2024-10654 for LR350 and CVE-2025-6916 for T6) allow remote attackers to access the admin interface without a password by sending a crafted HTTP GET request to the /formLoginAuth.htm endpoint with specific parameters (authCode=1, goURL=home.html, userName=admin, action=login). The repository consists of three markdown files: a README summarizing the vulnerabilities and two detailed markdown files, each describing the vulnerability and PoC for a specific device. No executable code is present; the repository serves as documentation and PoC for manual exploitation. The attack vector is network-based, targeting the web management interface of the affected routers.
