CVE-2018-6000 Information

Description

An issue was discovered in AsusWRT before 3.0.0.4.384_10007. The do_vpnupload_post function in router/httpd/web.c in vpnupload.cgi provides functionality for setting NVRAM configuration values which allows attackers to set the admin password and launch an SSH daemon (or enable infosvr command mode) and consequently obtain remote administrative access via a crafted request. This is available to unauthenticated attackers in conjunction with CVE-2018-5999.
