CVE-2024-46434

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.
