Description

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

Security Summary

CVE-2024-39765 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 command injection vulnerability also exists in the custom_interface POST parameter. These issues allow a specially crafted HTTP request to trigger arbitrary command execution on the device. The vulnerability carries 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) and was published on 2025-01-14.

An authenticated attacker with high privileges (PR:H) can exploit these vulnerabilities over the network with low complexity and no user interaction required. By sending a malicious HTTP request to the affected endpoints, the attacker achieves arbitrary OS command execution, potentially compromising confidentiality, integrity, and availability across the device's scope with high impact.
