A weakness has been identified in UTT 进取 512W 1.7.7-171114. Affected is the function strcpy of the file /goform/formRemoteControl. [CVSS 8.8 HIGH]
A vulnerability has been found in UTT 进取 512W up to 1.7.7-171114. Affected by this issue is the function strcpy of the file /goform/formP2PLimitConfig. Such manipulation of the argument except leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A flaw has been found in UTT 进取 520W 1.7.7-180627. The impacted element is the function strcpy of the file /goform/formArpBindConfig. Executing manipulation of the argument pools can lead to buffer overflow. The attack may be performed from remote. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Buffer overflow in UTT 520W firmware version 1.7.7-180627 allows remote authenticated attackers to cause a denial of service via crafted input to the addHostFilter parameter in the websHostFilter endpoint. Exploit code is publicly available, but no active exploitation in the wild has been confirmed.
Buffer overflow in the DNS filter configuration interface of UTT 520W firmware 1.7.7-180627 allows adjacent network attackers with low privileges to cause denial of service by submitting an overly long timeRangeName parameter. Public proof-of-concept code is available, but exploitation requires authenticated access from the local network. The vendor did not respond to disclosure and no patch is available.
