Consider a carelessly written web application for an online-shopping site, which stores the price of each item as a hidden form variable in the web page sent to the customer; when the customer submits the form, the information from the hidden form variable is used to compute the bill for the customer. What is the loophole in this scheme? (There was a real instance where the loophole was exploited by some customers of an online-shopping site before the problem was detected and fixed.)

Consider a poorly built web application for an online shopping site that saves the price of each item as a hidden form variable in the web page given to the consumer. What is the flaw in this plan? (In one case, clients of an online retailer took advantage of the flaw before it was rectified.)
The inventor of an online banking application could have included a hidden function that sends him an email with account information if a customer's balance rises beyond a certain threshold, say $10,000. Do you know what sort of assault it is, and what are the possible consequences?
In Java ,write a program that will act like an Bank Management app. In order to access the app, the customer must enter their user name and their passcode. After 3 incorrect attempts at entering the user name and password, the program will end. The list of legitimate users along with their user ID, passcode and account balance will be provided to you. There are only 5 functions that can be carried out by the app: 1 - Deposit (adding money to the account) 2 - Withdrawal (removing money from the account) 3 - Balance Inquiry (check current balance) 4 - Transfer Balance (transfer balance from one account to another) 5 - Log Out (exits/ends the program) Note: No need for GUI
Consider the possibility that the developer of a piece of online banking software included a secret function to the application that gives him access to the account details of any account with a balance of at least $10,000. What may happen if this is an assault, which is what it seems to be?
Write a program that asks a user to enter a first name, a last name, and a year, andconstruct an account ID in the format of:firstname.lastnameYYwhere the field “firstname” is user’s first name allowing no more than (first) five letters;the field “lastname” is user’s last name allowing no more than (first) six letters; and thefiled “YY” is the lower two digits of the year. For example:first name entered: Michaellast name entered: Richmondyear entered: 1985 the constructed account ID will be: Micha.Richmo85
Consider a piece of online banking software that includes a hidden function that allows the developer to see the account information for any account with a balance of at least $10,000. This scenario is conceivable. If this was an assault, who knows what the repercussions may be?
A web application for an online shopping website that was not created very well hides the price of each item as a hidden form variable on the web page that is shown to the customer. What exactly is wrong with this strategy? Some customers of an online shopping site took advantage of the loophole in the system before the problem was identified and fixed in one instance.
What exactly is Blazor, and how exactly does it function? How is Razor different from the programs that are available elsewhere? It has been said that Blazor is possible to construct user interface components not in JavaScript but rather in C# and.NET, as opposed to using JavaScript as the language of programming. As a consequence of this, what do you consider to be the positives and negatives of the current circumstance?
Write a Java program with two methods, main and exchange that asks to input two double variables, then prints them, and calls the exchange method to exchanges the values of these two variables. The exchange method receives two values for its parameters, prints them, then exchange values of parameters and prints their new values.
For this project, your task is to mark up a letter that needs to be hosted on a university intranet. The letter is a response from a research fellow to a prospective PhD student concerning their application to the university. Block/structural semantics Use appropriate document structure including doctype, and <html>, <head> and <body> elements. In general, the letter should be marked up as an organization of headings and paragraphs, with the following exception. There is one top level heading (the "Re:" line) and three second level headings. Use an appropriate list type to mark up the semester start dates, study subjects, and exotic dances. Put the two addresses inside <address> elements. Each line of the address should sit on a new line, but not be in a new paragraph. Inline semantics The names of the sender and receiver (and Tel and Email) should be marked up with strong importance. The four dates in the document should have appropriate elements containing…
