View Replies View RelatedForm To Email SPAM Bot Protection
I've recently had my ASP site attacked by these stupid bots and have tried a captcha protection, but it doesn't help.
Here's the problem:
I have a form where people send an enquiry to a client from my database (over 5000). After hitting the submit button, an email is posted to the client, a copy is sent to us and the info is published to a database for record / stat keeping.
I have put the captcha protection in the form, but although the tests show that the captcha form works, the emails are still sent off, therefore allowing the bot attacks.
There must be a gap I can plug with the captcha before the email is posted off or info sent to the database.
I have a formchecker running which forces required fields, and that works fine. I'd like the captcha to work the same. Before the form goes to the confirmation page, it must validate the captcha.
What can I do?

Stop Spam In The Text Input Field
I have a website with a Guessbook section. Lately I noticed someone copy and pasted a long http address to promote viagra.. I believe he simply copy and paste the whole link into the text input field and submit several times. It created multiple entries in my guessbook.
How can I prevent this? I was thinking if it is possible for me to write some code to disable people using the control-p to paste text in my text input field.. Can I really do that? What other options do I have?

I'm using if for when the user deletes a record from the database. People using the website try and delete more than one record at a t time by placing commas between the IDnumber ie. 1,2,5,9 etc.
This creates an error. So instead of this error appearing, how can I get a small alert box telling hte user he/or she has entered the wrong data type?

Preventing Session Variables
In ASP classic pages,I want to know if it's possible to prevent
session variables from becoming zero length strings? I have tried
setting the Session.Timeout to a large value, but alwas, after 20
minutes, my session variable times out. I also tried setting the
session timeout in IIS manager to a high value, but this did no good
either.I just want to allow one particular session variable to last a long
time.
Preventing / Removing Duplicates
I have a permission tracking app that I am working on, and I have made the insert page for it. I am having issues on how to prevent duplicates from getting entered.
Currently the interface for the app has a mixture of select boxes, list boxes and checkboxes. The form submits the page to processAIMR.asp and then does the inserting. I am using a loop to insert a new record for each checkbox checked or listbox entry selected. Code:
Preventing Form Caching
Does anyone know how to prevent the browser from automatically adding the password to a form after a user name is entered? I need to be able to over ride the brower setting so turning off the option in IE is not really a solution.
View Replies View RelatedPreventing Refresh Page
I have a form that sends info to a preview page, then to a thank you page. The thank you page gets the data passed from the rpeview page and sends an email.
How can I prevent the user from refreshing the page, so it doesn't send the email again.
Preventing Concurrent Logins
I would like to prevent a user from logging in with their user/password combination on a different computer or even a different browser window, if they are already logged in. I have a login page, from which I use a DB check to verify user/password info. Also, I have a bit loggedIN field in the DB, which I use to see if they are currently logged in; if so, I prevent them from logging in a second time.
Unless they click the "Log Out" button, then the DB value does not get changed. Any suggestions as to how I can log them out, even if they simply close the browser window or jump to a different page?
Preventing Error In One's Application
For instance here's a simple select statement Code:
("SELECT a, b,c d, e, f FROM Table WHERE a = "&CInt(j)&" and c= 0")
j is a dimmed variable which is a and it's numeric. Is the above protected against any non numeric instances? Like j=2,345..i've tested this and it works i'm just trying to see if i've covered all my tracks.
Preventing A 2nd Form Submission
How do people go about preventing the user from submitting a form for a 2nd time? For example, the user submits a form, clicks on the back button, and the submits the form again. I have used various techniques in the past (depending on circumstances) but I'd be interested in the techniques you guys currently use.
View Replies View RelatedPreventing Multiple Includes
Is there a way in ASP to prevent including the same file more than once?
Example:
dbutil.asp needs constants.asp, so I include constants.asp inside dbutil.asp.
transact.asp also needs constants.asp, so I include constants.asp inside transact.asp.
transact.asp doesn't need stuff in dbutil.asp, and dbutil.asp doesn't need stuff in transact.asp.
Then later I might have a main.asp that needs both dbutil.asp and transact.asp. So I include them both. However, the constants.asp will be found to be included twice!
What can I do to creatively prevent multiple inclusion of the same file in ASP? I know how to do it in C and C++, but I can't apply that to ASP, it seems.
Preventing Double Bookings
I have created an Intranet in my office using ASP (of course). Within it is a booking system, allowing booking of conference rooms, digital camera and other equipment. It works perfectly...almost, as there is no way to prevent double bookings.
I really don't know where to begin with this one. All bookings go to an Access DB, into a single table. The bookings have a start time and an end time (24hr).
I would like it so that when the user submits the form, if there is a clash in times instead of saying, thanks for your booking, to redirect them back to the booking page saying there is already a booking for this time and that I am very sorry!
I guess I have to check some value in access and return the info back to the webpage before it chooses where to redirect the user.
Preventing Session ID Replay Attack
I am developing a Simple ASP Website with a login page. I want to
know how can I change Session ID after login and also Close the current
Session after User closes the Window or gets logged out of the Website. So
that every time user logs in into the website, Session ID will be unique.
SQL Injection And Preventing Querystring Abuse
My client received an email from a user who mentioned that by accident they had been typing (over the querystring I guess), and the url had become:
default.asp?pageid='asd
They then received a SQL Server error message.
My client contacted their webhost, who came back to them promptly and talked of 'SQL Injection', they said that we would need to secure the code as well as the permissions on the database(which I believe they have done)..
This is something I had over looked, and started to write a fix for a couple of nights ago...but I dont think its 100%....
Basically I now do this at the top of my default.asp page ...
Preventing Form Injection On Classic ASP Pages
I've seen plenty of articles and utilities for preventing form injections for ASP.NET, but not too much for classic ASP. Are there any good input validation scripts that you use to avoid form injection attacks? I'm looking for good routines I can reuse on all of my form processing pages.
View Replies View RelatedPreventing Multiple Login Prompts When Using 2 Different Domains
We have 2 domains for internal purposes: one for users (have to login
and domain has SSL) and another for sponsors (have to login and domain
does NOT have SSL).
Now when a user logs in and there are pages that have info from the
sponsors domain, users are asked to login again with a warning message
saying if they want to see secure and nonsecure information. How can
I bypass the second login? Is there something I can do in active
directory, IIS, or ASP to not have the second login appear?

ASP Code - Anti Spam Verification Code
I'm looking for sample code that will require a use to enter a code from a scued image format.
I'm sure you've seen them before where the image is barely readable by a human and the user has to enter the code correctly to submit the form.
I'm looking for ASP code and NOT ASP.NET code as I am supporting a legacy site.
Preventing Cert Warnings - Redirect From Mydomain.com To Www.mydomain.com, How?
SSL cert on our site is for www.mydomain.com.
When you enter our site with just mydomain.com (without the www) and then proceed to a section of the site that is https, the user receives a cert warning since mydomain.com doesn't match up with www.mydomain.com.
What is the easiest way to globally and seamlessly redirect users from mydomain.com to www.mydomain.com to prevent this? The site has about 3000 pages so changing every page with request_querystring isn't really an option.
It would be great if it would work off of child pages too, i.e., mydomain.com/somepage.asp would also redirect to www.mydomain.com/somepage.asp.
