Description

Multiple OS command injection vulnerabilities exist in the login.cgi set_sys_init() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary code execution. An attacker can make an unauthenticated HTTP request to trigger these vulnerabilities.A command injection vulnerability exists within the `restart_min_value` POST parameter.

Security Summary

Multiple OS command injection vulnerabilities, classified under CWE-77, affect the login.cgi set_sys_init() functionality in the Wavlink AC3000 router running firmware version M33A8.V5030.210505. These flaws, tracked as CVE-2024-39760 and published on 2025-01-14, allow a specially crafted HTTP request to trigger arbitrary code execution. One specific instance involves the `restart_min_value` POST parameter, enabling attackers to inject malicious operating system commands.

The vulnerabilities carry 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), indicating critical severity with network accessibility, low complexity, no privileges or user interaction required, and scope change leading to high impacts on confidentiality, integrity, and availability. Unauthenticated remote attackers can exploit them by sending a malicious HTTP request to the affected endpoint, achieving arbitrary code execution on the device.
