| Título | Trendnet TEW-821DAP v1.12B01 CWE-319: Cleartext Transmission of Sensitive Information |
|---|
| Descrição | During the firmware update process, there is a firmware download vulnerability in program ssi(/www/cgi/ssi). In the firmware download, the device applies hard-coded firmware download url and use http protocol instead of https protocol. Therefore, the firmware download is vulnerable to the MITM attack. Once the hackers obtain the url, they could overwrite the url to perform firmware modification attack or redirect it to a malicious url to perform redirection attack. This issue in the firmware update process of Trendnet TEW-821DAP (firmware version:v1.12B01) allows attackers to execute arbitrary code or cause denial of service via overwriting or redirecting the firmware upload url. |
