Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 42.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SC-7 (Boundary Protection) and SI-10 (Information Input Validation).
Deeper analysis
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.
