Watch Out for Recent WordPress Gumblar PHP Exploit

May 12, 2009 · 120 comments

Kristi wrote a guest blog post at TechJaws about the attack last weekend on her well known Kikolani Blog by the PHP Script Injection Exploit in WordPress 2.7.1.  Kristi explains how she restored her blog and dealt with the issue. The UnMask Parasites blog provides additional details on what is known about this particular malware which has been dubbed the Gumblar .cn Exploit.

Gumblar exploit does NOT affect only WordPress. It can target any site using .php including Drupal, PhotoPost and even the Bangalore Telecom Web site.

The resources below will assist you in assessing your risk, increasing security for your WordPress blog and removing this exploit if you are already affected.

InStockPhones is referring to Google Page Rank. There are many explanations of what it is online including this one on What is Google PageRank.

There is much disinformation online about almost everything and especially about SEO so never believe everything you read.

I have noticed that in the recent google PR update, it does not update the PR for most blogs powered by WP and this could be the reason that why google did this.

Hello,

I don’t watch the PR updates very closely but I know that many blogs that are more tightly focused on SEO do. While I need to update it you may be able to find some of the best blogs that cover that subject on my personal GrowMap MyAlltop page.

I had no idea there were so many threats to blogs out there. As a newbie, I guess I have been pretty naive. Thanks for providing me with the tools to protect myself.

I am not sure if my previous comment got through. I was asking if there is any way to strengthen your security for the wordpress blogs.

I didn’t realise wordpress is so vulnerable. I now have some concerns over the wordpress blog that I am using now. Is there any other to make it more safe?

Good advice if it will be picked up quickly before more exploits.

Wordpress has to update for bugs and security flaws so often that it only pays to bother upgrading when its a very critical security flaw.

Thanks for the head’s up. Even though WP lets you upgrade wordpress right in the dash, it’s still something i’m worried ver because i tend to think it will break something..

There must be some helpful plug ins for WP to protect them with these PHP exploits and as well as the other stupid hacking techniques, i know there must be but needs an expert suggestion.

There’s a lot of talk about hacks to WP based sites. It’d be great if you can write a post about what to do after such a hack. A clear step-by-step guide or something would help.

Hello,

Security is a specialty that I usually leave to experts. Although I have a very technical background I rely on others to adminstrate technical aspects in my blogs. I did include a link to how to recover from this one and will gladly update this post with any other relevant links I find or that my readers can suggest.

One reason why everyone should regularly upgrade to the latest version of WP. Hope this exploit has been handled in 2.8.6!

All bloggers need to be aware that in order to restore any site there needs to be a backup (ideally a CURRENT backup). While most better hosting companies should do this for you it is unwise to rely on that. It is better to set up backups that are automatically emailed to you.

Thanks for the heads up about this matter. I just started using WP about 6 weeks ago and have noticed this kind of thing happens a lot…i guess thats the downside of using the platform…in any case, staying in tune will help us all remove these types of threats.

Hello Adam,

I don’t hear about these types of issues too often. Given the huge number of WordPress blogs we are fortunate there aren’t more of these problems.

I have seen the same thing with our website admin, someone told me a small script basically a SQL injection which can pass me easily through every admin of my website, i informed my IT manager to take care of this and after a few days, i went there again and put the same injection script but this time an awful message appeared which is basically for the person who is accessing that admin with SQL injection or you can say me for the time being but when i asked my manger that what is its remedy and tell me the way, he did not tell me anything but later on i got it from some forum where i got my manager’s username who is asking the same answer and i got a solution from there. Its basically hacking but a kinda cool hacking. :)
