Guys, what's the matter with your form on the download page? I've entered my true phone number in any combination I could think of, just to have the form return with "Please gimme a *valid* number". I'm surely not going to change my phone number for the sake of a piece of software. Well, I'm glad to tell you that 877-656-7058 was finally accepted. You should know the number - it's from the "contact HP" page!

Please explain to whoever made that form that not everybody on this planet has 10 digit phone numbers. Also, explaining clearly what your idea of a valid number looks like might be a sensible thing to do...

Tried many times to download the scrawls- failed because in order to download i got to key in my phone number.  Everty  time i key in my phone  number, it will return me invalid phone number.  Pls advise regarding this matter.

The download page for this product needs to validate the input correctly as you cannot enter valid data only rubblish!

(seems the wrong way round to me).  For non US people e.g. UK . phone numbers are not exactly 10 digits and postal codes are not exactly 5 digits.

Unable to download Scrawlr due form registration complains on phonenumber input. Even it is correct.

When I went to download scrawlr I found that the code checking the form fields for zip and phone number is broken for non US locations. It tries to enforce a US format ZIP code (our postcodes have 4 digits) and some sort of phone number that appears to choke on an international dialling prefix. This despite selecting "outside US" from the dropdown. Consequently I had to make up fields that would get past the checks which makes their entry pretty pointless for HP.

Oh dear. This "useful" tool is clearly going to be used by hackers (or worse - script kiddies) to determine which sites are vulnerable! I mean how perfect a tool can a hacker ask for - this thing even gives them the table names!

whats new in this tool ...lot of tool in market like this

if only we could download outside of us - keeps throwing back invalid zip/postal code on download page

"Will not test forms for SQL Injection (POST Parameters)"

I think that the tool is pretty useless without testing forms, don't you?

Interesting stuff.  Hey we're a hosting provider and are considering implementing a new security policy requiring that all customers hosting web applications on our servers modify their code to read from read-only datasources and write to write-only datasources.  SQL injections an admittedly still be executed on the write datasources, but we think it might at least slow hackers down and provide an additional layer of security.  Think it's worth the trouble?  Is this a common practice?  Thanks!

I will be getting back to the "Day in the Life of the DBA" series of posts, but I got this from the security

Doesnt' support POST forms or Javascript. In other words, this demo tool can't actually test anything that any web developer would have written since, oh, say 2001.

Epic fail.

In response to edddy:

update footable set last_name="Jones" where row_id="47";

Write-only users tend to be useless if you ever have to update rows based upon criteria. Assuming your users do more than keep a database of page hits, your solution has a serious problem.


Hi everyone, thanks for your feedback, a lot of people are pretty critical about our decision to not include testing of POST parameters. we thought about it, but the original scope of this tool was to find the same types SQL injection vulns that were recently responsible for the compromise of over 500,000 sites (some estimates suggest 2 million sites). I know, most people would think something like this wouldn't be so prevalent but it would seem that the majority of web sites are still developed without regard to security issues. It's out hope with this tool that we can build awareness of this issue and help folks out there justify the need to consider security issues when they are building and testing their applications. If folks have feature requests or other rants and raves, please feel free to let us know in our Scrawlr forum at


This is similar to many tools available in the hacker community.

Re modified code ? ahem....

itz totally useless ... in market already lot of tool like this.

itz not proper crawling thing !

It would be nice if the tool could use cookies from previous authentications or allow the tester to input their credentials prior to initiating the crawl.  Without one of these features, the tool can't crawl websites that require authentication so it's not very useful.  

Is this tool just a subset of HP/SPI Dynamics' SQL Injector tool?  If I already own that own, should I bother with this tool?

Reply to Richard Jackson:

SQL injection can be used to steal data on a read-only database (such as account numbers and addresses).  It can also be used to run code on the server if the DB engine hasn't been hardened.  Your suggested limitations do not add protection but will instead break some well designed sites.

We Mac users need to be able to check the vulnerabilities of our web sites too, but we can't use the MSI file. Are there any plans to create software that I can use on OSX?

thanks for the info

The comic is xkcd

The tool is useless, scrawl is entirely unable to detect even the simplest vulnerabilities, i went as far as pasting an example injection into the url bar and it okayed that!!! I also have an intentionally vulnerable site with local only access that we are using to configure our new IDS and it didn't find a thing... seriously, if you take anything away from this, let it be the comic.

HP make hacking tools? *** OFF, newb cakes

Erik, If's tough trying to "train" developers, seems they are all from the "show me" state. Raising awareness is nice, getting in the face of developers with their tablenames is much nicer, finding the offensive code to protect an infrastructure is best. You get us 5/8 of the way there.

Well the tool is pretty cool, but there is a glitch in one of the scripts that reads out the database. The tool performs a: select cast(db_name(dbid) as int)  from master..sysprocesses where spid=@@SPID

which when encrypted looks like:


The script should in fact read:


The cast has to be to nvarchar instead of int to be able to read out the database name. :-)

Roll on developers for version 2.0?

Poorly written web code is one of the most causes of sql injection!.

Interesting post.


I just tried to run this on my site.

It keeps saying scan did not complete (Scrawl limit reached).

This tool seriously needs a requirement that you place a certain file in the root of your website before it will scan.  This is what Google Apps does to make sure you own the domain (or at least have access to change the files in it).  Without this feature in place, this tool will do as much harm as it does good.

That said, this is an awesome tool.  I have been looking for something like this for months, and I have patched my site in a matter of minutes.

Pingback from  Scrawlr - check *your* website for SQL injections |

What sort of 'injection' can happen without a field to inject sql into?  And so, what sort of injection can happen witthout POST and form support?  

I'm afraid I don't see the use of this.

I ran scrawlr on my site as I had already been infected once

However the page htat was infected was not in the list of pages scanned

Has anyone any ideas what is the problem?

The author of this article may want to visibly acknowledge as the source of the comic strip to avoid being a ***.

my site got hit thought id use this but it doesnt help at all. nothing is vulnerable.

Just curious how it works & what it searches for. I tested it on a site with know vulnerabilities and it didn't find any...
