Vulnerability from variot
Trendnet AC2600 TEW-827DRU version 2.08B01 contains an improper access control configuration that could allow for a malicious firmware update. It is possible to manually install firmware that may be malicious in nature as there does not appear to be any signature validation done to determine if it is from a known and trusted source. This includes firmware updates that are done via the automated "check for updates" in the admin interface. If an attacker is able to masquerade as the update server, the device will not verify that the firmware updates downloaded are legitimate. Trendnet AC2600 TEW-827DRU Exists in a digital signature verification vulnerability.Information may be tampered with. Trendnet AC2600 TEW-827DRU is a wireless router.
Trendnet AC2600 TEW-827DRU version 2.08B01 has a security vulnerability
