A logistics company's vulnerability scan identifies the following vulnerabilities on Internet-facing devices in
the DMZ: SQL injection on an infrequently used web server that provides files to vendors SSL/TLS not used for a website that contains promotional information
The scan also shows the following vulnerabilities on internal resources: Microsoft Office Remote Code Execution on test server for a human resources system
TLS downgrade vulnerability on a server in a development network In order of risk, which of the following should be patched FIRST?
A. Microsoft Office Remote Code Execution
B. SQL injection
C. SSL/TLS not used
D. TLS downgrade

Answers

Answer:

A. Microsoft Office Remote Code Execution

Explanation:

From the given options, we have;

The web server having a SQL injection is infrequently use

The information on the website having SSL/TLS not used is promotional

The location of the server having  a TLS downgrade is on a development network

The location of the Microsoft Office Remote Code Execution is on a human resource system test server

Therefore, given that the test server, is the deployment source of the main server, and that with a Remote Code Execution, RCE,  cyber attack, the attacker is able to make commands work on other computers, the RCE attack on the test server is a potential access of an attack on the main servers, and should be patched first.

Answer:

B. Sniffer

Explanation:

The type of program that is being discussed is called a Sniffer. This can either be a software or hardware that allows the user to intercept data flowing from a computer to the internet in real-time before it reaches its destination. The program can be very vague and intercept all the data coming and going to the target computer or it can be very specific and intercept only the data in which it was programmed to target (sniff out). Cyber Criminals use these programs/devices to steal valuable information that they know a user is going to send sooner or later over the internet.

An attacker gained remote access to a user's computer by exploiting a vulnerability in a piece of software on the device. The attacker sent data that was able to manipulate the return address that is reserved to store expected data. Which vulnerability exploit resulted from the attacker's actions

Answers

"A Buffer overflow" vulnerability exploit resulted from the attacker's actions.

Whenever a software or an application writes too much data into a buffer, causing neighboring storage regions to have been corrupted as a consequence, this could be determined as Buffer overflow.

⇒ There are two kinds of Buffer overflow attacks such as:

Stack-based - It will become more popular to use such memory, as well as that's only available during implementation of any code.Heap-based - Those attacks seem to be more difficult to execute because they entail overflowing overall storage capacity allotted for a program further than the space needed for something like the program's present activities.

Thus we can say that the correct answer is a Buffer overflow.

While using a Web-based order form, an attacker enters an unusually large value in the Quantity field. The value she entered is so large that it exceeds the maximum value supported by the variable type used to store the quantity in the Web application. This causes the value of the quantity variable to wrap around to the minimum possible value, which is a negative number. As a result, the Web application processes the order as a return instead of a purchase, and the attacker's account is refunded a large sum of money. What type of attack has occurred in this scenario

Answers

Answer: integer overflow

Explanation:

The type of attack has occurred in this scenario is a integer overflow. An integer overflow occurs when there's an attempt by an arithmetic operation to create a numeric value which is outside the range which the given numbers are able to represent.

In this, the integer overflow occurs when the result of the integer operation cannot be able to fit in the allocated memory space which then brings about an unexpected result.
