CVE-2024-39785
Wavlink Wl-Wn533A8 Firmware m33a8.v5030.210505
Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:HSummary
CVE-2024-39785 is a critical-severity Injection (CWE-74) 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 7% 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 map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-39785 consists of multiple command execution vulnerabilities in the nas.cgi add_dir() functionality of the Wavlink AC3000 router running firmware version M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary command execution, with a specific command injection issue in the adddir_name POST parameter. These flaws fall under CWE-74 (Improper Neutralization of Special Elements used in an OS Command) and were published on 2025-01-14 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).
An attacker with high privileges can exploit these vulnerabilities by sending an authenticated HTTP request to the affected nas.cgi endpoint. Successful exploitation grants arbitrary command execution on the device, potentially allowing full compromise including data exfiltration, persistence, or further network pivoting given the high-impact CVSS metrics across confidentiality, integrity, and availability in a scoped attack.

Security testing in development catches injection vulnerabilities before release.
Logging supports detection of injection attempts but does not prevent the weakness.
Monitoring activities can identify active injection attacks after they occur.
Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.
Application security requirements explicitly call for controls against injection attacks in software design.
Secure architecture principles reduce injection surfaces but do not prescribe specific neutralization techniques.
