Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Enforces approved authorizations to block unauthorized HTTP POST requests to the setQuickCfgWifiAndLogin function that modify WiFi settings and admin credentials.
Remediates the specific access control flaw in Tenda W18E firmware V16.01.0.8(1625) through timely installation of vendor patches or updates.
Prohibits sensitive actions like WiFi reconfiguration and admin credential changes without identification and authentication, directly countering the permitted unauthorized access.
NVD Description
Tenda W18E V16.01.0.8(1625) is vulnerable to Incorrect Access Control. An attacker can send a specially crafted HTTP POST request to the setQuickCfgWifiAndLogin function, which allows unauthorized changes to WiFi configuration settings and administrative credentials.
Deeper analysisAI
CVE-2024-46432 is an Incorrect Access Control vulnerability (CWE-284) affecting the Tenda W18E router on firmware version V16.01.0.8(1625). The issue resides in the setQuickCfgWifiAndLogin function, where an attacker can send a specially crafted HTTP POST request to bypass authorization checks. This enables unauthorized modifications to WiFi configuration settings and administrative credentials without proper authentication.
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), indicating exploitation from an adjacent network with low complexity and no required privileges or user interaction. An attacker on the same local network segment, such as via WiFi or Ethernet proximity, can remotely alter critical device settings. This grants high-impact control over confidentiality, integrity, and availability, allowing the attacker to reconfigure WiFi SSIDs/passwords, reset admin accounts, and potentially lock out legitimate users or pivot to further network compromise.
