CVE-2024-39794

Estado: ModificadaAlta (7.2)—

Multiple external config control vulnerabilities exist in the nas.cgi set_nas() proftpd functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to permission bypass. An attacker can make an authenticated HTTP request to trigger these vulnerabilities.A configuration injection vulnerability exists in the `ftp_port` POST parameter.
