D-Link DIR-1950 up to v1.11B03 does not validate SSL certificates when requesting the latest firmware version and downloading URL. This can allow attackers to downgrade the firmware version or change the downloading URL via a man-in-the-middle attack.
The product uses OpenSSL and trusts or uses a certificate without using the SSL_get_verify_result() function to ensure that the certificate satisfies all necessary security requirements.
