Re: [PHP] Dinamic generate PDF : which way ? (classes, docbook)
Hello Robert, I would suggest that if your data is such that it can use DocBook, definitely go the DocBook route. You can also use Apache's Cocoon publish your DocBook content to PDF/HTML/RTF/SVG/TXT etc. Here are some samples that use Apache Cocoon to perform dynamic conversion to PDF/HTML: http://www.xml-dev.com/blog/#88 Here are some other utilities to convert to PDF: http://www.xml-dev.com/blog/#101 This one is pretty good: http://html2pdf.seven49.net/seven49.aspx?

Sometimes they only differ by the name of the company so my first attempt would be to generate templates in word and ask/replace for the values needed. I am evaluating the http://www.ros.co.nz/pdf/, www.fpdf.org and php classes that generate pdf and as another option use docbook to convert. I am not sure which way is better. From my point of view: a) Both classes seem to be fine but in order to generate (static) tables and other elements I will need a lot of programming calls/variables. So I'd have a manual and perhaps tedious/error procedure to convert the document into the programable-version of it. b) I do not have experience with DocBook (even tough I can code html and latex) but I could use an editor to generate the document with the tables, place images etc. Identify the template variables and call docbook to generate the pdf. I'd still have to manually convert the file but would not need a lot of calls to generate a table or even use a php programmer. I am assuming the the tags needed are more easly understanded than $pdf-addCell($data,width..)

Re: [PHP] OpenLDAP+MD5 Passowrds+PHP != Work?
I don't think this will work. Why do you need to MD5 the passwd if you
sending it over LDAPS:?? (LDAP over SSL)?
Thanks.

Hi, Attempting to connect to an OpenLDAP server to authenticate a
user, just want to see if the password the user passes is the stored
password if true. I can get the LDAP connection to connect to the
server, but unless I switch the LDAP server to use only clear I
continually get a 'Invalid Credentials' error (passwords dont match).
I am using LDAP MD5 to hash passwords on the server. If I take and
echo out the password the routine below is using and compare it to the
password on the server they match exactly?! Even if I include {MD5}
at the front it still always gives me Invalid Credentials.
Here is an example of the code I am using to check the password:
function CheckPassword($username,$password){
$dn = uid= . $username . ,ou=People,dc=domain,dc=net;
$pw = trim(base64_encode(pack(H*,md5($password;
$ldapconn = ldap_connect(ldaps://server_address/) or die(Could
not connect to LDAP server!);
if ($ldapconn) {
$ldapbind = ldap_bind($ldapconn,$dn,$pw);
if ($ldapbind) {
return true;
}
}
}
I am using OpenLDAP v2.1.30 and PHP 4.3.8, for what its worth I am
using Gentoo and my make flags include ldap.
Thanks for any pointers.
Regards,
Steven

[PHP] CSRF attack not possible in I.E. 6.01 SP1?
Hello All, I am working on securing an application that uses CDSSO (Cross Domain Single Sign On). I am trying to reproduce the CSRF (Cross Site Request Forgery) attack (using img/ TAG) in I.E. 6.01, but am unable to do so. However the attack works on Mozilla and other older browsers. My question: Is I.E. 6.01 SP1 doing something to foil the CSRF attack, i.e. only allow image extensions .gif .png .jpeg? Regards, Saqib Ali http://validate.sf.net DocBook XML - XHTML / PDF Convertor
RE: [PHP] CSRF attack not possible in I.E. 6.01 SP1?
Thanks Chris, Yup I think my posting is very on-topic. The application that I am working on is written in PHP. And I m sure all PHP developers check their applications for CSRF vulnerability, in various browsers (including I.E. ). As a PHP/Java developer, I would be interested to know what I.E. is doing in their browsers to prevent CSRF attacks. I m not trying to start a browser war here.

Re: [PHP] CSRF attack not possible in I.E. 6.01 SP1?
Hello, I m not saying the I.E. completely fixed the CSRF attacks, by only allowing .jpg .gif .png files. But it might be one possible way to minimize CSRF attack, just like using POST vs GET can help minimize the chances of that attack. BTW, using POST instead of GET does NOT guarantee that an CSRF attack will not work, either. Thanks.

Why is so important if Internet Explorer allows URLS of images where the file name is only .jpg, .png, or .gif? A url can be something like: http://www.site.com/script.php/image.jpg?logout=true Internet Explorer might think that the file is a .jpg and that script.php is a directory but only the target web server knows which is the program. Or a PHP code might be contained in a image.jpg file.

Re: [PHP] CSRF attack not possible in I.E. 6.01 SP1?
Hello Chris, Upon your suggestion, I used a sniffer to sniff traffic for the web app that I am working on. To my surprise, the data captured during the sniff for both browsers was exactly the same. Which mean my theory of limiting the img/ TAG to .gif .jpeg .png is NOT true. So now I am completely clueless as to why this particular attacks works in Mozilla but not in IE. Any ideas? Thanks.

For example, using something like ethereal, capture the request and response for Mozilla, and then do the same for IE 6.01 SP1. Short of that, you could create a URL specifically made for testing this. You can create a PHP file called csrf.php and another called csrf.png. Make .png files be interepreted as PHP (just for the purposes of this test), and then you can log a lot of useful information in your test scripts. Hope that helps.

Re: [PHP] CSRF attack not possible in I.E. 6.01 SP1?
Hello Curt, Yes, the /. system depends on cookies to keep the user logged in. However a CSRF attack is NOT trying to access a third party cookie. The web browser make the same GET request whether it is using img/ TAG or the user clicking on a link. So in either case the cookies are in the context of the website to which the cookies belong. Maybe Chris can correct me, if I am wrong here. Thanks.

RE: [PHP] CSRF attack not possible in I.E. 6.01 SP1?
Hello Ed, To give some details: I am unable to re-produce a CSRF attack when the victim is using a I.E. 6.01 SP1 (all patches applied). However the attack works in Mozilla and other older browsers. I can't give you the exact code for attack (for security reasons), but it is similar to the following: If you insert the following HTML code in any web page residing at any domain, it will cause you to be logged out of /. if you previously logged in the /. system: img src=http://slashdot.org/my/logout; height=1 width=1 This type of attack makes use of CSRF. Try to insert the above HTML line a web page of your choice, and then load the web page. If you are using Mozilla, it will log you off from /. However in the latest build of I.E. it doesn't work, whereas it should work. Thanks.
