Authenticated command execution via unfiltered ping target
Published May 25, 2025 · Updated May 29, 2025
Command injection in Netcore NBR1005GPEV2, NBR200V2, and B6V2 20250508 allows remote authenticated users to execute commands. The tools_ping function inserts the unfiltered url value into a ping command string and passes that string to system(). A valid ubus session token is required; exploitation runs shell commands with the router service's privileges and can alter data or interrupt service.
