Summary

CVE-2024-34544 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 20.5% 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-2024-34544 is a command injection vulnerability in the wireless.cgi AddMac() functionality of the Wavlink AC3000 router running firmware version M33A8.V5030.210505. The flaw allows a specially crafted HTTP request to trigger arbitrary command execution on the device.

An authenticated remote attacker with high privileges can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation grants high-impact confidentiality, integrity, and availability effects across the system's scope, as reflected in its CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H). This enables full arbitrary command execution on the targeted router.

Details on mitigation, including any patches or workarounds, are available in the Cisco Talos Intelligence advisory at https://talosintelligence.com/vulnerability_reports/TALOS-2024-2044.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
Why these techniques?

Command injection in public-facing web CGI directly enables remote exploitation of the application (T1190) and arbitrary Unix shell command execution (T1059.004).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly prevents command injection by requiring validation and sanitization of HTTP request inputs to the vulnerable wireless.cgi AddMac() function.

prevent

Addresses the root cause by requiring timely remediation of the known command injection flaw through patches or workarounds as detailed in the advisory.

prevent

Limits the impact of arbitrary command execution by enforcing least privilege on the processes handling authenticated HTTP requests to the web interface.
