I guess that there are a lot of busy sysadmins around at the moment. My web logs are full of crud like:
and much lengthier entries trying to exploit the log4j vulnerability.
In my case (and for this instance) I’m not that bothered because, luckily, I don’t run Apache, or any of its frameworks or the log4j2 java logging library. But the scale of the problem must be huge if the ‘bots are probing non-apache servers. You’d think they would at least check the server software before continuing the attack.
