Published: 14 January 2025
Summary
CVE-2024-36272 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 25.0% 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-2024-36272 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.
