This HTTP API receives the credentials as base64 encoded in the Authorization HTTP header. However, a missing length check in the code allows an attacker to send a string of 1024 characters in the password field, and allows an attacker to exploit a memory corruption issue. This can allow an attacker to circumvent the account protection mechanism and brute force the credentials. If the firmware version Amcrest_IPC-AWXX_Eng_N_V2.420.AC00.17.R.20170322 is dissected using the binwalk tool, one obtains a _user-x.squashfs.img.extracted archive which contains the filesystem set up on the device that has many of the binaries in the /usr folder.

Amcrest cloud services does not perform a thorough verification when allowing the user to add a new camera to the user\u0027s account to ensure that the user actually owns the camera other than knowing the serial number of the camera. This can allow an attacker who knows the serial number to easily add another user\u0027s camera to an attacker\u0027s cloud account and control it completely. This is possible in case of any camera that is currently not a part of an Amcrest cloud account or has been removed from the user\u0027s cloud account. Also, another requirement for a successful attack is that the user should have rebooted the camera in the last two hours. However, both of these conditions are very likely for new cameras that are sold over the Internet at many ecommerce websites or vendors that sell the Amcrest products. The successful attack results in an attacker being able to completely control the camera which includes being able to view and listen on what the camera can see, being able to change the motion detection settings and also be able to turn the camera off without the user being aware of it. Note: The same attack can be executed using the Amcrest Cloud mobile application."

Esto puede permitir que un atacante que conoce el n\u00famero de serie agregue f\u00e1cilmente la c\u00e1mara de otro usuario a la cuenta de la nube de un atacante y la controle completamente. Esto es posible en el caso de que cualquier c\u00e1mara que actualmente no sea parte de una cuenta en la nube de Amcrest o haya sido eliminada de la cuenta en la nube del usuario. Adem\u00e1s, otro requisito para un ataque exitoso es que el usuario deber\u00eda haber reiniciado la c\u00e1mara en las \u00faltimas dos horas. Sin embargo, ambas condiciones son muy probables para las nuevas c\u00e1maras que se venden a trav\u00e9s de Internet en muchos sitios web de comercio electr\u00f3nico o proveedores que venden los productos Amcrest. El ataque con \u00e9xito hace que un atacante pueda controlar completamente la c\u00e1mara, lo que incluye poder ver y escuchar lo que la c\u00e1mara puede ver, poder cambiar la configuraci\u00f3n de detecci\u00f3n de movimiento y tambi\u00e9n poder apagar la c\u00e1mara sin que el usuario est\u00e9 consciente de ello.

If one TELNETs into the device and navigates to /mnt/mtd/Config folder, one can observe that it contains various files such as Account1, Account2, SHAACcount1, etc. This means that if one navigates to http://[IPofcamera]/current_config/Sha1Account1 then one should be able to view the content of the files. The security researchers assumed that this was only possible only after authentication to the device. However, when unauthenticated access tests were performed for the same URL as provided above, it was observed that the device file could be downloaded without any authentication."

If the firmware version V2.420.AC00.16.R 9/9/2016 is dissected using binwalk tool, one obtains a _user-x.squashfs.img.extracted archive which contains the filesystem set up on the device that many of the binaries in the /usr folder. The binary \"sonia\" is the one that has the vulnerable function that sets up the default credentials on the device. If one opens this binary in IDA-pro one will notice that this follows a ARM little endian format. The function sub_436D6 in IDA pro is identified to be setting up the configuration for the device. If one scrolls to the address 0x000437C2 then one can see that /current_config is being set as an ALIAS for /mnt/mtd/Config folder on the device. If one TELNETs into the device and navigates to /mnt/mtd/Config folder, one can observe that it contains various files such as Account1, Account2, SHAACcount1, etc. This means that if one navigates to http://[IPofcamera]/current_config/Sha1Account1 then one should be able to view the content of the files.
