regardin XSS

« on: August 09, 2007, 11:53:17 PM »

What i do need to know is that how encoding specification in html coding helps preventing these attacks.Means i have been reading articles on the same and they say that specifying the character encoding helps prevent XSS since it helps in determining special characters.Now i am n;t getting this.Plz explain how does that happen and how charset encoding specification helps prevent XSS.

If you properly filter/sanitize your input and any gateways/variables, disallow code, etc. you will prevent XSS. Simple as that.

This page is being used as an example of XSS vulnerabilities over from sla.ckers.org.

http://www.ethicalhacker.net/component/option,com_smf/Itemid,54'%22%3E%3Cscript%08%3Ealert(%22xss%22)%3C/script%08%3E/script%3E,666/topic,1584.0/

This URL also discloses an SQL injection vulnerability on this very site.

Aha. "mos_menu"... Mambo/Jooma in use == vulnerable. Sad to see, really.

Thank you for pointing this out. I'm sure Don will be looking into the fix for this ASAP.

You're all welcome.

As a Linux System Admin for a managed hosting company, I see many of these vulnerabilities nightly (I'm a late-night shift worker). Sadly, many of these vulnerabilities exist with Mambo/Joomla sites. I usually recommend against using those packages, myself.

i'm sleepy so its probably there, but i dont see the page were it talks about how and why drupal is so inherently better than the other CMS's out there. or its just because it doesnt use all the mos_whatever modules?

Chris,

You asked what I recommend, not what is "recommended". There isn't a page that I based that info off of -- it's from personal experience. I have yet to see a major drupal installation that has been routinely hacked, cracked and used to host child porn, IRC (eggbot anyone?), phishing scams, etc., or provide a way to test privilege escalation attacks after gaining shell access as the Apache system account user. As for Mambo/Joomla, I see these literally every night I am at work. Many times it is the same sites again and again.

A number of sysadmins I know from work or from other associations use Drupal. That's how I learned of it, myself.

Perhaps I should put up a page. But then it would be drowned out by pages with expertise like "Why chmod 777 is NOT a security risk". Ya know?

yup i am following on that.

do you think its because there arent as many people running drupal as opposed to joomla that is resulting in what you are seeing? or something else?

if something is secure only because people arent targeting it (yet) that seems like you may be in either the 1) just wait the hacks will come category or 2) the user and development population is low and dont expect patches or new updates.

oh and since we are talking about CMSs, do any of them have a update management system that would tell you that moduleX or ModuleY are outdated and should be upgraded?

Yeah, I don't buy the Microsoft-ish argument about "popularity==vulnerability". Anyway, Drupal may or may not be popular. Don't know.

mos_* refer to major [platform-]components of Mambo/Joomla, I believe, and not [add-on] components. The best resource for finding the security vulnerabilities seems to be SecurityFocus and Milw0rm, and not those two packages. They seem more focused on promotion than information (last I looked).

For fun and profit:

XSS and SQL Injection exploit still not patched

« Reply #11 on: January 04, 2008, 08:59:49 AM »

The XSS and SQL injection exploit revealed in this thread for this forum is still not patched or mitigated. If I can be of assistance, let me know (privately).
