Description

A stack-based buffer overflow vulnerability exists in the wireless.cgi set_wifi_basic() 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 this vulnerability.

Security Summary

CVE-2024-36493 is a stack-based buffer overflow vulnerability (CWE-121) in the set_wifi_basic() functionality of the wireless.cgi component within Wavlink AC3000 firmware version M33A8.V5030.210505. The issue arises when processing a specially crafted HTTP request, which can overflow the stack buffer and enable arbitrary command execution.

An authenticated attacker with high privileges (PR:H) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction required (UI:N). Exploitation leads to high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) with a changed scope (S:C), as reflected in its CVSS v3.1 base score of 9.1. This allows the attacker to execute arbitrary commands on the affected device.
