Summary

CVE-2024-39360 is a critical-severity Command Injection (CWE-77) 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 30.8% 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-2 (Flaw Remediation).

Deeper analysis

CVE-2024-39360 is an OS command injection vulnerability (CWE-77) in the nas.cgi remove_dir() functionality of the Wavlink AC3000 router running firmware version M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary code execution on the affected device.

An attacker with high privileges (PR:H) who has obtained valid authentication can exploit this vulnerability remotely over the network (AV:N) with low complexity (AC:L) and no user interaction required (UI:N). Successful exploitation grants arbitrary code execution, with 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), enabling high-impact confidentiality, integrity, and availability violations in a changed scope (S:C).

The Talos Intelligence advisory TALOS-2024-2054, available at https://talosintelligence.com/vulnerability_reports/TALOS-2024-2054, provides further details on this vulnerability.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly prevents OS command injection by enforcing input validation mechanisms at the nas.cgi remove_dir() HTTP request entry point.

SI-2 Flaw Remediation good match
prevent

Ensures timely identification, reporting, and correction of the specific command injection flaw in the Wavlink router firmware.

AC-6 Least Privilege partial match
prevent

Limits the impact by enforcing least privilege, reducing the number of high-privilege authenticated users able to send the malicious HTTP request.
