Security Summary

CVE-2024-39763 consists of multiple OS command injection vulnerabilities (CWE-77) in the internet.cgi set_add_routing() functionality of the Wavlink AC3000 router running firmware version M33A8.V5030.210505. A specially crafted HTTP request targeting the `gateway` POST parameter can lead to arbitrary command execution on the device.

These vulnerabilities carry 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). An authenticated attacker with high privileges can exploit them remotely over the network with low complexity by sending a malicious HTTP request, resulting in full arbitrary OS command execution and high-impact compromise of confidentiality, integrity, and availability across an expanded scope.
