Edimax EW-7438RPn Mini OS Command Injection via mp.asp
An OS command injection vulnerability exists in the Edimax EW-7438RPn firmware version 1.13 and prior via the mp.asp form handler. The /goform/mp endpoint improperly handles user-supplied input to the command parameter. An authenticated attacker can inject shell commands using shell metacharacters to achieve arbitrary command execution as the root user. Exploitation evidence was observed by the Shadowserver Foundation on 2024-09-14 UTC.
