Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the buffer overflow vulnerability by requiring timely remediation through firmware patching specific to CVE-2024-36272.
Prevents stack-based buffer overflow by validating and sanitizing specially crafted HTTP inputs to the usbip.cgi set_info() function.
Mitigates exploitation of the stack-based buffer overflow via memory protections like DEP and ASLR to block arbitrary code execution.
NVD Description
A buffer overflow vulnerability exists in the usbip.cgi set_info() 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.
Deeper analysisAI
CVE-2024-36272 is a stack-based buffer overflow vulnerability in the set_info() functionality of usbip.cgi within the Wavlink AC3000 router running firmware version M33A8.V5030.210505. The flaw is triggered by a specially crafted HTTP request, 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).
An attacker with high privileges (PR:H) can exploit this vulnerability remotely over the network (AV:N) with low complexity (AC:L) and no user interaction required (UI:N). Successful exploitation leads to high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), with a scope change (S:C) that could enable arbitrary code execution or full system compromise on the affected device.
