The DBPOWER U818A WIFI quadcopter drone provides FTP access over its own local access point, and allows full file permissions to the anonymous user. The DBPower U818A WIFI quadcopter drone runs an FTP server that by default allows anonymous access without a password, and provides full filesystem read/write permissions to the anonymous user. A remote user within range of the open access point on the drone may utilize the anonymous user of the FTP server to read arbitrary files, such as images and video recorded by the device, or to replace system files such as /etc/shadow to gain further access to the device. Furthermore, the DBPOWER U818A WIFI quadcopter drone uses BusyBox 1.20.2, which was released in 2012, and may be vulnerable to other known BusyBox vulnerabilities.

In the following Java example the method createBankAccount is used to create a BankAccount object for a bank management application.
}
return account;However, there is no authentication mechanism to ensure that the user creating this bank account object has the authority to create new bank accounts. Some authentication mechanisms should be used to verify that the user has the authority to create bank account objects.
The following Java code includes a boolean variable and method for authenticating a user. If the user has not been authenticated then the createBankAccount will not create the bank account object.
}// authenticate user,// if user is authenticated then set variable to true// otherwise set variable to false...
return account;account.setBalance(balance);ExploitPedia is constantly evolving. Sign up to receive a notification when we release additional functionality.
