Security Summary
CVE-2024-39769 consists of multiple stack-based buffer overflow vulnerabilities in the internet.cgi set_qos() functionality of the Wavlink AC3000 firmware version M33A8.V5030.210505. These issues, classified under CWE-120, are triggered by a specially crafted HTTP request targeting the `cli_mac` POST parameter. The vulnerability received a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H) upon publication on 2025-01-14.
An authenticated attacker with high privileges (PR:H) can exploit these vulnerabilities remotely over the network (AV:N) with low attack complexity and no user interaction. By sending a malicious HTTP POST request, the attacker triggers the buffer overflow, potentially achieving high impacts on confidentiality, integrity, and availability across the affected scope (S:C), such as arbitrary code execution or system crashes.
