Am having a lot of problems with a wordpress installation. The version is 2.3 and the hosting guy said that my wordpress need to be updated because is suffering several spam attacks - people sending emails through the system. Looks like their using wordpress 2.3 to do it.
PROBLEM: this wordpress has to many modifications and it can't be updated that easy. I need a work-around.
Is there a world known vulnerability in wordpress 2.3 code that you could point at? I know there are plenty, but one that is enabling attackers to send emails from my server. Any?
Am a bit stuck, don't know were to start.
Thanks for reading,
