In the boa server program\u0027s CGI handling function formWlEncrypt, there is a lack of length restriction on the wlan_ssid field. This oversight leads to potential buffer overflow under specific circumstances. For instance, by invoking the formWlanRedirect function with specific parameters to alter wlan_idx\u0027s value and subsequently invoking the formWlEncrypt function, an attacker can trigger buffer overflow, enabling arbitrary command execution or denial of service attacks."

En la funci\u00f3n de manejo de CGI formWlEncrypt del programa del servidor boa, no hay ninguna restricci\u00f3n de longitud en el campo wlan_ssid.

Por ejemplo, al invocar la funci\u00f3n formWlanRedirect con par\u00e1metros espec\u00edficos para alterar el valor de wlan_idx y, posteriormente, invocar la funci\u00f3n formWlEncrypt, un atacante puede provocar un desbordamiento de b\u00fafer, lo que permite la ejecuci\u00f3n arbitraria de comandos o ataques de denegaci\u00f3n de servicio."
