Affected devices do not check the TFTP blocksize correctly. This could allow an authenticated attacker to read from an uninitialized buffer that potentially contains previously allocated data.

Affected devices store the CLI user passwords encrypted in flash memory. Attackers with physical access to the device could retrieve the file and decrypt the CLI user passwords.

Affected devices use a weak encryption scheme to encrypt the debug zip file. This could allow an authenticated attacker to decrypt the contents of the file and retrieve debug information about the system.
