CVE-2024-39770
Published: 14 January 2025
Description
Multiple buffer overflow vulnerabilities exist in the internet.cgi set_qos() 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 these vulnerabilities.This vulnerability exists in the `en_enable` POST parameter.
Security Summary
CVE-2024-39770 consists of multiple stack-based buffer overflow vulnerabilities (CWE-120) in the set_qos() functionality of the internet.cgi script on the Wavlink AC3000 router running firmware version M33A8.V5030.210505. These issues arise from improper handling of the `en_enable` POST parameter in specially crafted HTTP requests, potentially leading to buffer overflows.
An authenticated attacker with high privileges (PR:H) can exploit these vulnerabilities remotely over the network (AV:N) with low complexity (AC:L) and without user interaction (UI:N). By sending a malicious HTTP request, the attacker can trigger the stack-based buffer overflow, achieving high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) across the affected scope (S:C), as reflected in the CVSS v3.1 base score of 9.1.
