CFImage Captcha error.

I am getting error when i am trying to display the captcha i
am getting the below error.
java.security.AccessControlException: access denied
(java.io.FilePermission
C:\Coldfusion8\tmpCache\CFFileServlet\_cf_captcha read)
In my local system its working fine. but after uploading the
file to the server, then i am getting that error. This be because
the CF server is trying to create a temp captacha file in the
folder which I dont have access to that shared folder.
But i could able to give the destination to the captcha. If i
am giving the destination, its not at all displaying anything.
how to overcome this issue?.

Fixed the problem! Turns out simple restarting of the cf
service resolved the issue.

CFImage Captcha

When using the CFIMAGE captcha function, I am getting a
broken image. The source code reads as this:
<img
src="/CFFileServlet/_cf_image/_cfimg892407289798721295.png">
Although I get no coldfusion errors and the page loads fine,
the image path is not found.
Why is this failing to load? Is it a mapping issue? And how
is this mapped?

Hi Oguz,
Here is the code:
<cfimage action="captcha" text='blah" overwrite="yes"
height='"75" width="300">
When the page renders this is the source
<img
src="/CFFileServlet/_cf_captcha/_captcha_img6225449526107627875.png"
alt="BS4H6D" height="75" width="300" />
If we try to use the destination attribute and map to our
images folder like this:
<cfimage action="captcha" text='blah" overwrite="yes"
destination="/images/picture.png" height='"75" width="300">
We get this when the page renders:
coldfusion.image.ImageWriter$ImageWritingException: An
exception occurred while trying to write the image.
However,
If we use this code:
<cfimage action="captcha" text='blah" overwrite="yes"
destination="picture.png" height='"75" width="300">
Then the image loads fine, but this is a waste since we have
no control over where to dump the photo. It creates the photo where
ever the cfimage fucntion is called and we are using a CFC to do
that so it will not be adequate.
Any ideas?

Cfimage captcha not showing locally

I am on cf9 and vista business.
When i upload my code to my host i can see the cfimage captcha, when i try it locally i don't see anything.
When i check the image url i get: http://localhost/CFFileServlet/_cf_captcha/_captcha_img3011810602272985780.png
That url trying i get:
HTTP Error 404.0 - Not Found
Does anyone has any experience setting this up correctly?

I know that this is old, but I ran into a similar problem.
Turned out that there was a URL Rewrite rule in place for SEO that was supposed to set the URL to lower case characters. This broke "/CFFileServlet" the ColdFusion settings. Apparently it is case specific.
Some navigation systems also use !File or !Directory evaluations that will break cfimage. This page has info regarding that problem:
URL Rewriting And ColdFusion's WriteToBrowser Image Functionality (CFFileServlet)
Check your SEO URL Rewrites. It may be causing the problem.

CFIMAGE captcha issue - Cannot find /CFFileServlet, possibly because server and webroot are on different drives

CFIMAGE captcha was working on my DEV system, where the wwwroot is in the same folder as CFServer is installed.
It is NOT working when I move it to staging, which is identical to production - including the fact that CFServer is on D: drive, but wwwroot is on E: drive.
Is there a way to map a location for the CFFileServlet folder? I think this is the reason it isn't working in staging.
V/r,
^_^

May want to check your web server to be sure it's not Denying access to that folder based URL Request filtering. Part of the ColdFusion lockdown guide recommends to Deny access to this folder unless you use CFImage, CFChart, CFPresentation, or CFReport.

Error 'Timer already cancelled' when using CFIMAGE - captcha

I've implemented captcha image using cfimage. Works fine on
our development system however, I'm getting a
'java.lang.IllegalStateException: Timer already cancelled' in our
production environment.
The first time I requested the page containing the captcha
image it took forever to load but eventially did. Susequent
requests to this page now produces the above error. Production
enviroment is running Coldfusion 8.01 in multiserver configuration
with latest hotfix applied, IIS 6.

Fixed the problem! Turns out simple restarting of the cf
service resolved the issue.

I remember that I got this error some time ago. A CF restart
solved it.

Forms without a CAPTCHA error message.

Has anyone received the below error? I don't want to use a CAPTCHA and have disabled it in the admin settings. Anyone know if I can at least stylize the error?
Multiple requests per IP address are rate-limited for forms without a CAPTCHA. Please contact the site owner or try again later.

Nope and you wont see it that in the real world really. It is because your using the form multiple times in a short space of time from the same IP. That is a hard system message.

Captcha error message

We have a client who wants a newsletter submission form without a captcha field. We have tested the form, but recently, we are getting the following error message...
Multiple requests per IP address are rate-limited for forms without a CAPTCHA. Please contact the site owner or try again later.
My assumption is that it is a security measure to prevent spamming, etc...
Am I correct?
If not, does anyone have an idea of the reason that it is there and how do I correct it either way?

Thanks
Chuck

but it doesnt solve the issue. you untick those boxes and it still pops up.
anything that connects to the internet for multiple devices through a router has (for the purposes of this arguement) a single IP address.
think wifi hotspots, think libraries, think agencies.
one IP address - we have a problem. people and devices dont just fit into a single easy to contain pidgeon hole!
not everyone wants, agrees with or needs a captcha.
I try to remove it, but alas anyone else using the same IP address in the next ten minutes will be blocked out.
thats not forward thinking or being "preventative" you've basically put a blanket on all BC sites and told us, use captcha (or our attempt at trying to make it kinda appear to work for you without it, but ultimately in a real world solution it will fail). thanks a bunch BC. once again.
looks like I either sit with that horrible red message (put it in a lightbox or alert window or something. but to a blank page is just nasty - and who feels the brunt of it? me! (and any other developer using BC) or sit with a horrible looking captcha (which makes me shudder...) neither are preferred solutions....

Cfimage CAPTCHA Not Displaying

Hi All,
I am creating the captcha using cfimage. In my project we have three different environment dev, stage , production. However I am getting the the captcha image for production and dev but in stagging I am not getting the captcha image. When I am checking captcha in firebug I am getting the image "src" attribute as, "/CFFileServlet/_cf_captcha/_captcha_img2787831475697289656.png" for all three environments but the image not displaying only for stage.
Please help me.
Thanks

Captcha error + no captcha image

Captcha image is not shown in the form. Additionally, I get the following error. Error executing command. The system() function is disabled.
Is it related to shell function on hosting? I do not have shell access on hosting server. Any workarounds or help?

Hi Saini,
please ask your hosting provider if they
(what I´m assuming...) disabled "system" within the php.ini´s "disable_functions" directive -- and of course, if they´re willing to enable it for your account

Cfimage, captcha and partitions

Forgive me if I am overlooking something blindingly obvious,
but we are having a problem using the captcha attribute of cfimage
action. With our installation of CF8 running on a separate
partition from our web root, the folder where the image is created,
under tmpCache below the CF8 folder, is apparently unreachable by
the servlet (?). Has anyone run in to this? Is there a simple
mapping solution? Or an xml file containing a path to edit? Any
help or pointers would be greatly appreciated.
Thanks.

CFIMAGE not working with certain JPG

Hi all,
Got an emergency here, hope anyone can help.
I find that more and more people are encountering problems using CFIMAGE -- no error is thrown when reading/saving certain jpg images, but the result image is just blank and gray.
The code is just simple:
<CFSET IM=ImageRead("C:\DSCN1570.JPG")>
<cfset ImageResize(IM,300,200,"highPerformance")>
<cfset ImageWrite(IM,"C:\DSCN1570-2.JPG")>
or even just:
<CFSET IM=ImageRead("C:\DSCN1570.JPG")>
<cfset ImageWrite(IM,"C:\DSCN1570-2.JPG")>
This happens after applying the latest hotfix for 8.0.1 (Cumulative Hotfix 2 for CF 8.0.1). If this patch is not installed the processing works.
Attached is an offending file. The code works if i replace the file with another jpg.
Any help is much appreciated. I'm running CF 8,0,1,195765 devt edition on Windows XP and my java version is 1.6.0_04. My metadata-extractor is 2.3.1.
Thanks,
Andrew

Yeah, sorry: missed the bit - that BKBK pointed out - about you saying you did some testing. To be honest, I would never release code into production without load-testing it first. Especially something that's perhaps already red-flagged as being a risk. Of course there was no real reason for you to think that the previously fixed issue had been regressed. So not - perhaps - a red flag. maybe just an amber one.
I don't believe load testing is a "nice to have", it's essential. In the past I just slapped my code into production after a bit of a click round to make sure it all seemed to work. Then we released some code which worked fine whilst only one person was accessing it, but had some severe logic flaws in it which made it fail - in a data-destroying sort of way - which caused us an awful lot of issues with the client (which in turn got me shouted @ by the boss), not to mention wasted time fixing everything.
That lead me to investigate whether we could have found that sort of thing had we load-tested: yes. Easily. Lesson learned. It also turned up a few other things we didn't notice which were easy tweaks which improved the performance of the app, and made the client happy again.
But anyway, that's just something to think about for future reference, I guess. I fully understand what you mean about time constraints often preventing one from taking the perfect foolproof approach to things: we've all done that. Just sux you got caught out by it.
As for bringing it to Adobe's attention... go here: http://cfbugs.adobe.com/cfbugreport/flexbugui/cfbugtracker/main.html.
It'd help if you could contrive a stand-alone test rig that can be made to fail under load.

Double trouble: email design and re Captcha

Hi,
I usually can do anything I need in Muse and now I hit a point where I don't know what to do. I got two problems and both are connected with Muse's email forms.
1) The design of the email I receive from my form.
I found the templates for the auto notification emails the form's sender receives after submitting the form and I was able to re-design the template. Now I want to re-design the email I receive from the form. Until now, I always get the Business Catalyst pre-styled email, two gray bars with the form's content in between. Since I am building the site for a customer and do not want to have them read the Business Catalyst "ads" in the mail, I would like to be able to re-design this email in the same style I did with the auto responder. Where can I do that?
2) Ever since I re-designed my auto-responder, re Captcha quit working. When I was using the form "as is" with Adobe's pre-formatted email templates, re Captcha worked fine. Now, with the changed auto responder template, I get the re Captcha error message every time I try to submit the form. I switched to BC Captcha and everything works fine, but I really want to use re Captcha.
Funny thing is: When submitting with re Captcha, the page itself disappears, I am redirected to my auto response email template where the re Captcha error message is displayed instead of the form's texts. I already trried reloading the re Captcha, the whole page, even quit and restarted my browser. As soon as I change the auto responder template, re Captcha does not work anymore.
Any help and ideas would be greatly appreciated!

Hi Aish,
since it is a client's website, I cannot link it publicly yet. But I can paste the template code I inserted:
<style type="text/css">
.mail {
    color: #0B3144;
    font-family: Constantia, "Lucida Bright", "DejaVu Serif", Georgia, serif;
.logo {
    vertical-align:top;
</style>
<table width="100%" border="0" cellspacing="3" cellpadding="3">
<tbody>
    <tr>
      <td align="left" class="mail"><p><strong>Customer's Name</strong><br>
          address
      <p> </p></td>
      <td align="right" class="logo"><img src="images/logo_email-01.png" width="250" height="75" alt=""/></td>
    </tr>
</tbody>
</table>
<table width="100%" border="0" cellspacing="3" cellpadding="3">
<tbody>
    <tr>
      <td class="mail">{tag_pagecontent}</td>
    </tr>
</tbody>
</table>
I can't see anything that should disturb re-Captcha. Do you?

Register page problem.

I am so confused, I want to add some anti-spam security to my upcoming register page but something is really wrong.
Note that my server is Coldfusion MX7 (i can not afford better) and because of that i can not use
cfimage(captcha).
This is what i have:
<cfset strLowerCaseAlpha = "abcdefghijklmnopqrstuvwxyz">
<cfset strUpperCaseAlpha = UCase( strLowerCaseAlpha )>
<cfset strNumbers = "0123456789">
<cfset strAllValidChars = (
    strLowerCaseAlpha &
    strUpperCaseAlpha &
    strNumbers
    )>
<cfset arrPassword = ArrayNew( 1 )>
<cfset arrPassword[ 1 ] = Mid(
    strNumbers,
    RandRange( 1, Len( strNumbers ) ),
    1
    )>
<cfset arrPassword[ 2 ] = Mid(
    strLowerCaseAlpha,
    RandRange( 1, Len( strLowerCaseAlpha ) ),
    1
    )>
<cfset arrPassword[ 3 ] = Mid(
    strUpperCaseAlpha,
    RandRange( 1, Len( strUpperCaseAlpha ) ),
    1
    )>
<cfloop
    index="intChar"
    from="#(ArrayLen( arrPassword ) + 1)#"
    to="8"
    step="1">
    <cfset arrPassword[ intChar ] = Mid(
        strAllValidChars,
        RandRange( 1, Len( strAllValidChars ) ),
        1
        )>
</cfloop>
<cfset strPassword = ArrayToList(
    arrPassword,
    )>
<cfif IsDefined("FORM.spamcode")>
    <cfif form.spamcode neq strPassword >
    not equal
    <cfelse>
   finally working
</cfif>
</cfif>
                 <cfif isdefined ("strPassword")>
                 <cfoutput>#strPassword#</cfoutput>
                 </cfif>
<form action="" method="post">
<label>
    <input type="text" name="spamcode" id="spamcode" />
</label>
</form>
this is just testing code but it is somehow messed up.
every time when i click on the submit button i get not equal!
I also need to add when i set up strPassword manualy instead of ArrayToList, for example
<cfset strPassword=test413> and then insert in form test413 and compare it everything is fine. You can copy/paste this code to test it. Any ideas please?

I get the feeling you could create the password more efficiently. But that's another matter. Your code does work.
I would generate the captcha word in a function. Then it will be run only when necessary. Something like this:
<cffunction name="getPassword" returntype="string">
<cfset var strPassword = "">
<cfset var strLowerCaseAlpha = "abcdefghijklmnopqrstuvwxyz">
<cfset var strUpperCaseAlpha = UCase( strLowerCaseAlpha )>
<cfset var strNumbers = "0123456789">
<cfset var strAllValidChars = (
    strLowerCaseAlpha &
    strUpperCaseAlpha &
    strNumbers
    )>
<cfset var arrPassword = ArrayNew( 1 )>
<cfset arrPassword[ 1 ] = Mid(
    strNumbers,
    RandRange( 1, Len( strNumbers ) ),
    1
    )>
<cfset arrPassword[ 2 ] = Mid(
    strLowerCaseAlpha,
    RandRange( 1, Len( strLowerCaseAlpha ) ),
    1
    )>
<cfset arrPassword[ 3 ] = Mid(
    strUpperCaseAlpha,
    RandRange( 1, Len( strUpperCaseAlpha ) ),
    1
    )>
<cfloop index="intChar" from="#(ArrayLen( arrPassword ) + 1)#" to="8" step="1">
    <cfset arrPassword[ intChar ] = Mid(
        strAllValidChars,
        RandRange( 1, Len( strAllValidChars ) ),
        1
        )>
</cfloop>
<cfset strPassword = ArrayToList(arrPassword,"")>
<cfreturn strPassword>
</cffunction>

<cfparam name="session.current_captcha" default="#getPassword()#" type="string">
<cfif IsDefined("FORM.spamcode")>
    
    <cfif compare(form.spamcode, session.current_captcha) eq 0>
         proceed: user entered the correct code
    <cfelse>
           stop spam: user entered the wrong code
    </cfif>
    
    <cfset session.current_captcha = getPassword()>
</cfif>
<cfoutput>
<form action="#cgi.SCRIPT_NAME#" method="post">
    <input type="text" name="spamcode" id="spamcode"><span><em>enter this exact code:</em> <strong>#session.current_captcha#</strong></span>
    <br>
    <input type="submit" name="sbmt" id="sbmt" value="Test it!">

After upgrade to CF9, CFIMAGE "Unable to create temporary file" error

We recently upgraded from CF8 to CF9 Enterprise. I'm getting an "Unable to create temporary file" error on
my CFIMAGE resize calls. We use sandbox security. I assume I need to grant write access to whatever folder CF uses for temp files, but which folder is it? The same code (and sandbox settings) ran fine in CF8....
Note, if I attempt to add C:\JRun4\servers\cfusion\SERVER-INF\temp to the sandbox for this particular app, CF crashes on all requests across all apps on the server with a:
Security: The requested template has been denied access to C:\JRun4\servers\cfusion\cfusion-ear\cfusion-war\WEB-INF\cfclasses\cfapp2ecfc1510154633.c lass.
The following is the internal exception message: access denied (java.io.FilePermission C:\JRun4\servers\cfusion\cfusion-ear\cfusion-war\WEB-INF\cfclasses\cfapp2ecfc1510154633.c lass read)
ColdFusion cannot determine the line of the template that caused this error. This is often caused by an error in the exception handling subsystem.
I need to restart CF to get everything working again.

Another update. Had a problem with a sandboxed CF9 site doing a simple CFIMAGE READ to a memory variable. Got an "Unable to create temporary file" error.
Inserted the following code in the file upload page:
<cfscript>
writeoutput("Temp Dir : " & createobject("java","java.lang.System").getProperty("java.io.tmpdir") );
</cfscript>
... and it reveals the temp directory as C:\WINDOWS\TEMP. Added that to the sandbox, and the CFIMAGE READ is working properly now.
Note this seems inconsistent with CFIMAGE RESIZE behavior which appears to use the CF GetTempDirectory() value, which in my case is C:\JRun4\servers\cfusion\SERVER-INF\temp\cfusion-war-tmp\
For reference, see the section "Sandbox Considerations" at this link:
http://help.adobe.com/en_US/ColdFusion/9.0/Admin/WSc3ff6d0ea77859461172e0811cbf364104-7fc8 .html#WSc3ff6d0ea77859461172e0811cbf364104-7fcc
