Survey Finds Most WordPress Blogs Vulnerable

Posted by kdawson on Thu May 24, 2007 12:10 PM

Security The Internet
BlogSecurity writes "Security analyst David Kierznowski shocked bloggers yesterday with a survey showing that 49 out of the 50 WordPress blogs he checked seem to be running exploitable versions of the widely used software. He said, 'The main concern here is the lack of security awareness amongst bloggers with a non-technical background, and even those with a technical background.' Mr Kierznowski also uncovered recent vulnerabilities in WordPress plugins that ship by default with the software, adding: 'WordPress users developing plugins must be aware of the security functions that WordPress supports, and ensure that these functions are used in their code.'"

      at my previous job there had been a programmer who used the same password for *everything*, and I do mean everything... from the mysql logins (both "root" and regular webapp), web site logins, shell accounts and the ssh passwords needed to move data around!

      I discovered he had a blog site, and guess what, his standard password worked on that too, both to login as him and as admin. Whilst tempted, I neither added nor deleted anything on his site, but I *did* go occasionally go through his blog posts and correct his spelling and grammar! He must have noticed because after many months of occasionally tweaking his content, the login finally stopped working. Yes, I'm talking about you, "smurphy" :-)

    I think it's about time web applications like WordPress included an update service. Put update notifications into an Atom feed pointing to tarballs incorporating an update script, patches, etc, and label them as security/minor/major. Have the system periodically retrieve them, automatically apply the security updates, and prompt the admin next time he logs in to apply the others.

    The only difficulty is that the developers need to have proper release management. No more bundling security fixes into whatever the latest development version is. No more releasing updates that fiddle with styles at the same time as fixing serious bugs. I don't think that's feasible for many web applications, but it's certainly achievable for bigger projects like Wordpress.

    I can't think of any web application that does this already off the top of my head. Does anybody know of any projects doing this?

        Wordpress provides an easy-to-use interface to do this, but it doesn't help anything if you upgrade your system. Your look and customizations will go "poof!" the moment you untar that new version.

        Actually, this isn't true -- provided you use some common sense about how you customize your Wordpress blog. It doesn't make a lot of sense to go ahead and apply all your customizations to a theme called "default," for example (though I'm sure that lots of people do this). When you go and untar the new version,

          That's assuming, of course, that you can use the old template. The new versions might contain changes to the modified files that can't be simply copied over.

    • From a technical point of view, this isn't usually possible. On most servers, web applications don't have the permissions to update themselves - the PHP scripts are run via mod_php as the 'httpd' or 'apache' user, while the scripts themselves are owned by whatever Unix account was setup to own and manage the domain. Sure, some hosting services run PHP scripts as the Unix user who owns the domain, but they seem to be in the minority.

      • Most applications that do update checks I've used only do so from the administration interface. e107 and jforum both check for updates. (php and java apps) Its possible to do the checks. However, downloading updates means the webapp has to have space to download files automatically. From a security perspective, it seems stupid to add this feature unless the webapp already needs writable space. The update feature could introduce an additional attack vector.

I am not saying there aren't plenty of older/vulnerable versions out there, but I think you get the point. The second issue is that relying on your extraction of a version number does not mean it's actually vulnerable. Patches or other mitigations could be in place.
