Discuss EC-Council 312-50 Exam Topic 9 Question 91

A company's Web development team has become aware of a certain type of security vulnerability in their Web software. To mitigate the possibility of this vulnerability being exploited, the team wants to modify the software requirements to disallow users from entering HTML as input into their Web application.

What kind of Web application vulnerability likely exists in their software?

ACross-site scripting vulnerability

BSQL injection vulnerability

CWeb site defacement vulnerability

DGross-site Request Forgery vulnerability

Suggested Answer: B

WEP encryption is an outdated and insecure method of protecting wireless networks from unauthorized access and eavesdropping.WEP uses a static key that can be easily cracked by various tools and techniques, such as capturing the initialization vectors, brute-forcing the key, or exploiting the weak key scheduling algorithm1. Therefore, you should recommend a more secure encryption method to enhance the security of the company's wireless network.

One of the most suitable replacements for WEP encryption is WPA2-PSK with AES encryption. WPA2 stands for Wi-Fi Protected Access 2, which is a security standard that improves upon the previous WPA standard. WPA2 uses a robust encryption algorithm called AES, which stands for Advanced Encryption Standard.AES is a block cipher that uses a 128-bit key and is considered to be very secure and resistant to attacks2.

WPA2-PSK stands for WPA2 Pre-Shared Key, which is a mode of WPA2 that uses a passphrase or a password to generate the encryption key. The passphrase or password must be entered by the users who want to connect to the wireless network. The key is then derived from the passphrase or password using a function called PBKDF2, which stands for Password-Based Key Derivation Function 2.PBKDF2 adds a salt and a number of iterations to the passphrase or password to make it harder to crack3.

WPA2-PSK with AES encryption offers several advantages over WEP encryption, such as:

It uses a dynamic key that changes with each session, instead of a static key that remains the same.

It uses a stronger encryption algorithm that is more difficult to break, instead of a weaker encryption algorithm that is more vulnerable to attacks.

It uses a longer key that provides more security, instead of a shorter key that provides less security.

It uses a more secure key derivation function that adds complexity and randomness, instead of a simple key generation function that is predictable and flawed.

Therefore, you should recommend WPA2-PSK with AES encryption as a suitable replacement to enhance the security of the company's wireless network.

I’m surprised they didn’t catch this earlier!

Cruz 11 months ago

Definitely XSS, but why not just sanitize inputs instead?

Truman 11 months ago

Wait, could it also be SQL injection? Just a thought.

Dana 12 months ago

Totally agree, HTML input can lead to XSS attacks.

Amber 12 months ago

Sounds like a classic case of Cross-site scripting vulnerability.

Lisbeth 1 year ago

I’m a bit confused about the options. I thought gross-site request forgery was a thing, but it doesn’t seem to fit this scenario.

Yoko 1 year ago

This question feels familiar; I think we practiced something similar in class. Disallowing HTML input definitely points towards XSS vulnerabilities.

Silvana 1 year ago

I’m not entirely sure, but I think SQL injection is more about database manipulation rather than HTML input. I might be overthinking it.

Johnson 1 year ago

I remember studying about Cross-site scripting, or XSS, and how it allows attackers to inject malicious scripts. This seems like it could be related.

Bettina 1 year ago

Interesting question. I'm going to have to think about this one a bit more. The wording is a little tricky, but I'm leaning towards the cross-site scripting vulnerability.

Lina 1 year ago

Okay, let me think this through. If they're worried about users entering HTML, that points to a cross-site scripting issue. I'll go with option A.

Anisha 1 year ago

I think the cross-site scripting vulnerability is the most likely answer here. Disallowing HTML input is a common mitigation strategy for that type of security flaw.

Gwenn 1 year ago

This one seems pretty straightforward. The key is that they're trying to prevent users from entering HTML, which suggests a cross-site scripting vulnerability.

Deandrea 1 year ago

Hmm, I'm a little unsure on this one. Could it also be a SQL injection vulnerability if they're trying to prevent users from entering certain types of input?

Nickolas 1 year ago

Okay, I've got this. The question is asking for a tool to validate performance and failure counts in near real-time, so that rules out Snapshot Debugger and Profiler since they're more for debugging and profiling. Smart Detection is for automated anomaly detection, not real-time monitoring. That leaves Live Metrics Stream and Application Map - and since the question specifically mentions validating performance and failures, I think Live Metrics Stream is the way to go.

XSS for sure. Gotta love those pesky hackers trying to inject scripts into your web pages. Glad the team is on top of it!

A) Cross-site scripting vulnerability

Craig 2 years ago

I'm going with option A. SQL injection would be my second guess, but the question is specifically about HTML input, so XSS is the way to go.
