Mitigating Controls (NIST 800-53 r5)AI
Requires validation of HTTP request inputs to adm.cgi rep_as_bridge() to prevent stack-based buffer overflows from specially crafted requests.
Implements memory protection mechanisms such as stack canaries and non-executable stacks to mitigate exploitation of the stack-based buffer overflow vulnerability.
Mandates timely patching of the specific buffer overflow flaw in Wavlink AC3000 firmware version M33A8.V5030.210505 as documented in CVE-2024-37184.
NVD Description
A buffer overflow vulnerability exists in the adm.cgi rep_as_bridge() 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-2024-37184 is a stack-based buffer overflow vulnerability (CWE-120) in the adm.cgi rep_as_bridge() functionality of the Wavlink AC3000 router running firmware version M33A8.V5030.210505. The flaw arises from a specially crafted HTTP request that overflows the buffer, as documented in the CVE description published on 2025-01-14. It has 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 impact across confidentiality, integrity, and availability.
An authenticated 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). By sending a malicious HTTP request to the affected adm.cgi endpoint, the attacker triggers the buffer overflow, which changes scope (S:C) and enables high-impact consequences, including potential remote code execution, full system compromise, data exfiltration, or disruption of the device.
