Authenticated command execution via stored NVRAM injection
Published Mar 31, 2025 · Updated Apr 2, 2025
Command injection in NETGEAR WNR854T firmware 1.5.2 allows remote authenticated users to execute commands through the web interface. The /bin/httpd email-alert flow inserts the email_address NVRAM value into a /bin/sendmail system command without sanitization. Authentication to post.cgi is required to store a backtick payload, and requesting /send_log.cgi executes it with the router service privileges.
