Summary
CVE-2024-37184 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Wavlink Wl-Wn533A8 Firmware. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 21.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
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.
Mitigation details are available in the Talos Intelligence advisory at https://talosintelligence.com/vulnerability_reports/TALOS-2024-2025. Security practitioners should consult this reference for patching instructions or workarounds specific to the Wavlink AC3000 device.
