TRENDnet TEW-821DAP Firmware Update cameo_dev.sh platform_do_upgrade_cameo_dev data authenticity
Summary
A vulnerability was found in TRENDnet TEW-821DAP up to 1.12B01. This impacts the function platform_do_upgrade_cameo_dev of the file cameo_dev.sh of the component Firmware Update Handler. Performing a manipulation results in insufficient verification of data authenticity. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitability is said to be difficult. 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.

Title
TRENDnet TEW-821DAP Firmware Update new_gui_update_firmware data authenticity
Summary
A weakness has been identified in TRENDnet TEW-821DAP 1.12B01. This issue affects the function find_hwid/new_gui_update_firmware of the component Firmware Update Handler. Executing a manipulation of the argument dest can lead to insufficient verification of data authenticity. The attack can be launched remotely. Attacks of this nature are highly complex. The exploitability is assessed as difficult. 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.
