Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the CVE by requiring timely identification, reporting, and remediation of the static login vulnerability in the router firmware.
Monitors and controls communications at network boundaries to block unauthenticated crafted packets from reaching the vulnerable wctrls functionality.
Validates information inputs from network packets to prevent specially crafted data from exploiting the static login mechanism and granting root access.
NVD Description
A static login vulnerability exists in the wctrls functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted set of network packets can lead to root access. An attacker can send packets to trigger this vulnerability.
Deeper analysisAI
CVE-2024-39754 is a static login vulnerability in the wctrls functionality of the Wavlink AC3000 router running firmware version M33A8.V5030.210505. The issue allows a specially crafted set of network packets to lead to root access on the affected device. It is classified under CWE-912 and was published on 2025-01-14 with a CVSS v3.1 base score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), marking it as critical.
An unauthenticated attacker with network access can exploit this vulnerability by sending specially crafted packets to the device. Successful exploitation grants root-level privileges, enabling high-impact compromise of confidentiality, integrity, and availability without requiring privileges, user interaction, or high complexity.
