Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents OS command injection by enforcing input validation mechanisms at the nas.cgi remove_dir() HTTP request entry point.
Ensures timely identification, reporting, and correction of the specific command injection flaw in the Wavlink router firmware.
Limits the impact by enforcing least privilege, reducing the number of high-privilege authenticated users able to send the malicious HTTP request.
NVD Description
An os command injection vulnerability exists in the nas.cgi remove_dir() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary code execution. An attacker can make an authenticated HTTP request to trigger this vulnerability.
Deeper analysisAI
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).
