Authenticated command injection via WPS PIN parameter
Published May 23, 2026 · Updated May 23, 2026
OS command injection in the webs component of Edimax EW-7438RPn 1.31 and earlier allows remote authenticated users to execute commands. The formWpsStart handler uses the attacker-controlled pinCode value in an OS command without neutralizing command syntax. Low-privileged network access to the management endpoint is required, and successful exploitation can alter appliance data or interrupt its service.
