Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
AC-3 mandates enforcement of approved authorizations for access to system resources, directly countering authentication bypass in the web management portal.
IA-2 requires identification and authentication of organizational users before network access, preventing unauthorized administrative login via crafted HTTP requests.
AC-14 prohibits sensitive functions like administrative access without identification and authentication, mitigating bypass vulnerabilities in management interfaces.
NVD Description
Tenda W18E V16.01.0.8(1625) suffers from authentication bypass in the web management portal allowing an unauthorized remote attacker to gain administrative access by sending a specially crafted HTTP request.
Deeper analysisAI
CVE-2024-46434 is an authentication bypass vulnerability affecting the Tenda W18E router running firmware version V16.01.0.8(1625). The flaw resides in the web management portal, where an unauthorized remote attacker can bypass authentication controls by sending a specially crafted HTTP request, granting full administrative access to the device.
The vulnerability has a CVSS v3.1 base score of 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-287 (Improper Authentication). An attacker with adjacent network access (e.g., on the same local network segment) requires no privileges or user interaction to exploit it. Successful exploitation allows the attacker to achieve high-impact confidentiality, integrity, and availability compromises, such as modifying device configurations, extracting sensitive data, or disrupting network operations.
Details on the vulnerability, including exploitation techniques, are documented in the advisory published by Redda Solutions at https://reddassolutions.com/blog/tenda_w18e_security_research. No specific patches or vendor mitigations are detailed in available information.
