Description

A vulnerability has been found in TRENDnet TEW-821DAP 1.12B01. This affects an unknown function of the file /www/cgi/ssi of the component Firmware Update. Such manipulation leads to cleartext transmission of sensitive information. The attack can be executed remotely. This attack is characterized by high complexity. The exploitability is reported as difficult. The exploit has been disclosed to the public and may be used. The vendor explains: "That firmware version will only work on our hardware version v1.xR. We have already EOL that product 8 years ago and are no longer selling". This vulnerability only affects products that are no longer supported by the maintainer.
