URL Vulnerability Checker 06-23-2013, 11:04 PM #1
Hello HC!
I've made an URL Vulnerability Checker in VB.NET feel free to fix my mistakes Smile Click here to download.

Virustotal result.

Nice one dude.
I'm working on a sql vulnerability checker in python language.
I can get some ideas from your program. Thanks.

RE: URL Vulnerability Checker 06-24-2013, 08:15 AM #3
Why not replacing "it must have http:// in front of your URL" with your program replacing the URL variable with "http://" + the input URL variable?

Code:
Imports System.Net
Imports System.IO
Imports System.Text

End Module

Look at the above code. I'm not sure that it is the correct syntax for a negative IF statement, (all my edits are in Main()) but I think so, looking at the rest of the code (I'm not a VB.NET coder). Whatever, I just edited the ReadLine function so that the user's variable will begin with http:// if it is not added (the user should type "http://http://" to have it start with "http://" as long as I added it before the input line. This means the user will hardly add it, but I added a check that will add it itself if missing). I also tried to center some more the initial header.

Look at the above code. I'm not sure that it is the correct syntax for a negative IF statement, (all my edits are in Main()) but I think so, looking at the rest of the code (I'm not a VB.NET coder). Whatever, I just edited the ReadLine function so that the user's variable will begin with http:// if it is not added (the user should type "http://http://" to have it start with "http://" as long as I added it before the input line. This means the user will hardly add it, but I added a check that will add it itself if missing). I also tried to center some more the initial header.

Just change this line;
Code:
url = Console.ReadLine("http://")
like this;
Code:
url = Console.ReadLine()

Hm, you're saying that it won't work like that (with "http://", like I did in my edit)? If not, I'm not getting what you mean.

Pretty basic, you should try adding some actual testing into it. Such as if you were to try a basic SQLi attack to test if it redirects you.

I don't know if there is a usage like Console.Readline("http://") I use just the Console.Readline() then check the first 7 digits of input.

That's definitely fine if you leave Console.Readline() (I don't really think the way I put it would work) but I'm just to add a "http://" in case missing instead of asking the user to do it itself (have a look at my code).

RE: URL Vulnerability Checker 06-25-2013, 06:39 PM #10
1. If you turned on Option Strict, you would see a ton of errors and warnings with this code being too implicit.

2. You're using a Function where some methods should really be Subs, becuse they don't return a value at all. The Function, Greetings() for instance only outputs to the console. How is this a proper function that expects a return value?

3. This is VB.net not VB6: In Function URLDecode...
Code:
URLDecode = TempAns

You should use a Return here instead

4. You have mixed return values. In the IstekGonder Function for instance, You're returning both a string here and an Integer if an exception is caught.

5. You're not being explicit with your variables:
Code:
Dim webResponse = ""

Which leads to my next point...
6. You're not using the As clause in places where it should be used; After function declarations, in variable declarations, etc...

7. You're main "method" of (poor) exception handling is with a Try Catch block. And with that i'll adivse you to read this page: http://msdn.microsoft.com/en-us/library/ms229005.aspx

8. Why are you returning 1's and 0's in places where a Boolean would probably be better?

9. You're not disposing of the underlying streams in some objects, specifically your WebRequests in this case, which is bad practice. If the GC decides to do a clean sweep, that is a computationally expensive process.

10. In your Main() Sub, that last Console.ReadLine() is unreachable code because you're using a goto that always loops back to the label before reading that method. And this leads me to the last of the points that I'll make about this code...

11. You shouldn't be using a goto here...

There are others, but you're not going to understand them if you're making mistakes like this in your code, so I won't post them for now.

Other than that, my criticism here is not intended to be insulting, so take it as feedback and as advice. I wrote this post out while I was looking through your code, so it's a mention of just some of the things I've noticed. If I wrote a program like this, I would probably make it plugin based, because this is only a fraction of the amount of vulnerabilities that could be looked for... And there's no reason to hard code the checking functionality for each and every one of them, because newer exploits and vulnerability methods come out all the time.
