CVE-2024-39294
Published: 14 January 2025
Description
A buffer overflow vulnerability exists in the adm.cgi set_wzdgw4G() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to stack-based buffer overflow. An attacker can make an authenticated HTTP request to trigger this vulnerability.
Security Summary
CVE-2024-39294 is a stack-based buffer overflow vulnerability in the set_wzdgw4G() functionality of adm.cgi within the Wavlink AC3000 router running firmware version M33A8.V5030.210505. The issue arises from a specially crafted HTTP request that overflows the buffer, as documented in the CVE description published on 2025-01-14. It is classified under CWE-120 and 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), indicating critical severity due to its potential for severe impacts.
An attacker requires high-level privileges (PR:H) to authenticate and send a malicious HTTP request over the network (AV:N) with low complexity (AC:L) and no user interaction (UI:N). Exploitation triggers the buffer overflow, enabling high confidentiality, integrity, and availability impacts (C:H/I:H/A:H) across a changed scope (S:C), potentially allowing arbitrary code execution or system compromise on the affected device.
