Security Summary

CVE-2024-39762 involves 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, particularly targeting the `netmask` POST parameter, can lead to arbitrary command execution on the device.

These vulnerabilities can be exploited by an authenticated attacker with high privileges (PR:H) who sends a malicious HTTP request to the affected component. Successful exploitation grants arbitrary command execution, potentially compromising the router's confidentiality, integrity, and availability, as reflected in the CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).
