Warning: OpenX backdoor (is your adserver compromised?)

[Walter]

As I know that the OpenX advertising script is pretty popular amongst forum admins:

Juergen Schmidt from Heise.de has detected that OpenX 2.8.10 contains a backdoor (!). OpenX today has released a new version 2.8.11 that is fixed:

How to upgrade your installation:
http://www.openx.com/docs/upgrading-openx

How to secure your installation:
http://blog.openx.org/09/security-update-how-to-secure-your-openx-installation/
(but of course that doesn't help anything against a backdoor in the ZIPs you download from the original website sigh)

How to detect if your system contains the backdoor:
Use

find . -name \*.js -exec grep -l '<?php' {} \;

to look for a Javascript file. If the file contains something like

this.each(function(){l=flashembed(this,k,j)}<?php /*if(e)
{jQuery.tools=jQuery.tools||{version:
{}};jQuery.tools.version.flashembed='1.0.2';
*/$j='ex'./**/'plode'; /* if(this.className ...

you have found the backdoor.

But in any case, upgrade to 2.8.11!

Glad I read your earlier threads about OpenX and learned about Google DoubleClick so I don't have to worry about this **** anymore.

Same here. I read Walter posts years ago about openx exploits when i still using the system. I moved to dfp soon after that.
Surprised he still puts up with that software

Using Openx is suicide for your business. This is simply a non secure software.
